+%What if there was a way to avoid having to install a broad range of scientific software from scratch on every HPC
+%cluster or cloud instance you use or maintain, without compromising on performance?
+
+Installing scientific software for supercomputers is known to be a tedious and time-consuming task.
+The application software stack continues to deepen, especially as the HPC user community becomes more diverse,
+computational science expands rapidly, and the diversity of system architectures increases.
+Simultaneously, we see a surge in interest in cloud computing for scientific computing. Delivering optimised
+software installations and providing access to these installations in a reliable, user-friendly, and reproducible
+way is an increasingly highly non-trivial task that affects software developers, HPC user support teams,
+and researchers running scientific workloads on HPC systems.
+
+This tutorial aims to address these challenges by introducing the European Environment for Scientific Software Installations
+(EESSI, pronounced as \emph{``easy"}), a collaboration between various European HPC sites \& industry partners. The goal of EESSI is to provide
+a shared repository of scientific software installations that can be used on a variety of systems, regardless
+of which flavor/version of Linux distribution or processor architecture is used, or whether it is a full size HPC
+cluster, a virtual machine in the cloud, or a personal workstation.
+
+We cover the basics of EESSI, different use cases for EESSI, how to add software to EESSI, and highlight some more 
+advanced features. We will also show how to engage with the community and contribute to the project.

+We anticipate this EESSI tutorial at ISC to be well attended with 20-50 attendees. This estimate is based on attendance at previous EESSI and EasyBuild events, including:
+\begin{itemize}
+\item A recent webinar series related to EESSI in May-June 2025 with over 150 registrations;
+\item The yearly EasyBuild User Meetings, with over 50 in-person attendees in 2025, alongside over 70 online registrations;
+\item An online EESSI tutorial in Dec'23 with over 130 registrations;
+\item The in-person (half-day) ISC'22 EasyBuild tutorial with about 20 attendees.
+\end{itemize}
+
+%HV: Do we have the attendance of the workshop series we did? 
+
+%KH I would've gone with 50/25/25, but this works too (maybe better even)
+% MG: This was just a blind guess ;)
+%KH seems about right I think, we want to keep it beginner-oriented, 25% advanced may be too much... maybe 50/30/20 is less awkward?
+% I love how 'awkward' is such an awkward word to type... :D (no, haven't had beer yet)
+
+% KH: Markus, I'm signing off for tonight... I'll be around tomorrow, definitely in the morning (have a student intern to keep busy in the afternoon, but I'll be around on Slack)
+%MG: Yea, I will also stop working soon
+
+% KH: do we need anything from Maxime? It's probably good to tell him that now, since he'll only be around after 1-2pm tomorrow.
+%MG: For the submission, we'll need a short bio (some text) For Alan and the two of us, I will copy from last year unless I receive an update.
+% KH I already asked him for a bio. And a picture. I'll mail that too. => DONE

+\subsection*{EESSI: the European Environment for Scientific Software Installations}
+
+EESSI\footnote{\href{https://eessi.io}{https://eessi.io}} is a collaborative project
+between different partners in the HPC community, supported by the MultiXscale EuroHPC Centre of Excellence.
+It provides a common stack of optimised scientific software installations for everything from laptops to HPC systems and cloud
+infrastructures. The project combines existing well-established projects like
+%EasyBuild\footnote{\href{https://easybuild.io}{https://easybuild.io}} to install software on top of a compatibility layer,
+%Lmod\footnote{\href{https://lmod.readthedocs.io}{https://lmod.readthedocs.io}} to provide a user-friendly user interface to those installations,
+%CernVM-FS\footnote{\href{https://cernvm.cern.ch/fs}{https://cernvm.cern.ch/fs}} to distribute the software installations to client systems,
+%and ReFrame\footnote{\href{https://reframe-hpc.readthedocs.io}{https://reframe-hpc.readthedocs.io}} to test this shared software stack.

+\emph{CernVM-FS} to distribute the software installations to client systems,
+and \emph{ReFrame} to test this shared software stack.
+
+%EasyBuild is used by well over 100 HPC sites worldwide (incl. JSC, CSCS, the Digital Research Alliance of Canada, LUMI,
+%\ldots),
+%has over 125 unique contributors on a yearly basis,
+%and an active Slack channel with over 830 members.

+
+%It has reached critical mass, a point where a large user base means more features and software being added regularly, with an accelerated adoption rate, and a welcoming and engaging community.
+%Attendance at the yearly EasyBuild User Meetings has been growing steadily, with close to 100 attendees at the 7th (virtual) edition in Jan'22.
+%As such, we strongly believe that EasyBuild, and the community behind it, will have a positive impact on the attendees' work.
+% The tutorial content is designed to help with getting started quickly and benefit from EasyBuild right after the conference.
+%The tutorial content will be designed to help the attendees getting started with the tool, so they can immediately benefit from it after the conference.
+
+It is an initiative built on the foundations of the EasyBuild community, which consists of hundreds of HPC sites and
+has attracted contributors from all around the world. EESSI takes things a step further, beyond a tool to install scientific software (like
+EasyBuild or Spack), by providing a ready-to-use uniform software stack that can be employed anywhere.
+
+\subsection*{Motivation \& goal}
+
+The motivation for EESSI is the observation that the landscape of computational science is changing in various ways.
+Additional families of general-purpose microprocessors including Arm 64-bit (aarch64) and RISC-V on top of
+well-established Intel and AMD processors (both x86\_64), and different types of GPUS (NVIDIA, AMD, Intel) are
+increasing the diversity in system architectures. The rapid expansion of computational science beyond traditional
+domains like physics and computational chemistry, including bioinformatics, Machine Learning~(ML), and Artificial
+Intelligence~(AI) leads to a significant growth of the software stack that is used for running scientific
+workloads. The emergence of commercial cloud infrastructure (Amazon EC2, Microsoft Azure, \ldots) and private cloud
+infrastructure (OpenStack, \ldots) has competitive advantages over on-premise infrastructure for computational workloads, such
+as near-instant availability, increased flexibility, a broader variety of hardware platforms, and faster access to new
+generations of microprocessors. In contrast, the human resources that are available in HPC user support teams
+to help scientists with getting the software they require installed (among many other things) remains limited.
+These reasons indicate that there is a strong need for more collaboration on
+building and installing scientific software to avoid duplicate work across researchers, software developers,
+and HPC user support teams.
+
+%It goes one step further by providing a truly uniform software stack.
+%It already has a wide spectrum of collaborators despite being a relatively young project.

+    \label{fig:eessi-high-level-overview}
+\end{figure}
+
+The main goal of EESSI is to provide a collection of scientific software installations that work across a wide range of
+different platforms, including HPC clusters, cloud infrastructure, and personal workstations and laptops, without making
+compromises on the performance of that software.
+%
+Software installations included in EESSI are optimized for specific generations of microprocessors by targeting a
+variety of instruction set architectures (ISAs), like for example \texttt{x86\_64} processors supporting the
+AVX-512 instruction set, and Arm processors that support SVE instructions.
+
+%To provide optimized installations of scientific software stacks for a diverse set of system architectures, the EESSI
+%project consists of 3 layers, which are constructed by leveraging various established open source software projects,
+%see Figure~\ref{fig:eessi-high-level-overview}.
+To provide optimized installations of scientific software stacks for a diverse set of system architectures
+The high-level design of EESSI consists of 3 layers, which are constructed by leveraging various established open source software projects,
+see Figure~\ref{fig:eessi-high-level-overview}. At the time of writing, EESSI includes over 600 unique software projects
+and supports 14 different CPU microarchitectures and 3 generations of NVIDIA GPUs, which totals to over 16,000 software installations.
+% the filesystem layer to distribute the software stack; the compatibility layer to level the ground across different client operating systems; the software layer to run optimized applications and provided their dependencies.
+%\begin{itemize}
+%\item The filesystem layer uses CernVM-FS to distribute the EESSI software stack to client systems
+%\item The compatibility layer levels the ground across different (versions of) the Linux operating system (OS)
+%      of client systems that use the software installations provided by EESSI. It consists of a limited set of libraries
+%      and tools that are installed in a non-standard filesystem location (a "prefix"), which were built from source for
+%      the supported CPU families using Gentoo Prefix.
+%\item The top layer of EESSI is called the software layer, which contains the actual scientific software applications
+%      and their dependencies. Building, managing, and optimising the software installations included in the software
+%      layer is done using EasyBuild, a well-established software build and installation framework for managing
+%      (scientific) software stacks on High-Performance Computing (HPC) systems. Next to installing the software itself,
+%      EasyBuild also automatically generates environment module files. These files, which are essentially small Lua
+%      scripts, are consumed via Lmod, a modern implementation of the concept of environment modules which provides a
+%      user-friendly interface to end users of EESSI. The initialisation script that is included in EESSI
+%      automatically detects the CPU family and microarchitecture of a client system by leveraging either
+%      \texttt{archspec}, a small Python library, or \texttt{archdetect}, a minimal pure bash implementation of the same
+%      concept.
+%\end{itemize}
+
+%By also covering some of the more advanced features (such as packaging builds, rpath-ing, user-space installations to complement/extend system installations) we want to convince more people to not only start using these tools, but also to actively join their (largely overlapping) respective communities, and maybe even to contribute back themselves in one way or another. We want to explicitly highlight the community-oriented aspects of both tools:
+
+%\paragraph{Target audience}
+%This tutorial is intended for HPC and domain support teams, application developers, and end-users of HPC systems. EasyBuild can help relieve attendees from the time-consuming and tedious tasks involved with installing scientific software stacks, by automating software installations and module file generation, and by serving as an excellent platform for collaboration with other HPC sites and support teams. It can also be utilized by end users and developers to manage a (partial) software stack themselves in an efficient way. Lmod provides end users with a powerful yet flexible way of managing their working environment through various advanced features that are missing in the well-established Tcl-based environment modules tool, while providing a responsive user interface by supporting an easily-maintained module files cache.
+
+%\paragraph{Content Level}
+%50\% introductory, 30\% intermediate, 20\% advanced
+
+%\paragraph{Prerequisites}
+%Basic knowledge of using a Unix-style command line interface is desirable. Some familiarity with the issues that arise when compiling/installing scientific software and using environment modules is helpful, though not strictly necessary. A virtual machine image or access to a prepared environment on AWS (Amazon Web Services) will be provided for the hands-on, but no prior knowledge is required to use it.
+
+%\paragraph{Tutorial content}
+%We will start of by sketching the traditional way in which HPC support teams deal with installing software, and outline the problems with it. Based on these observations, we will motivate the need for tools that support automation and offer a simple yet powerful user interface to efficiently tackle these problems, and explain how EasyBuild and Lmod fulfill these requirements.
+
+% The tutorial covers installing and configuring EasyBuild, and basic usage through hands-on demos and guided examples. It showcases the main features and capabilities, and also briefly describes an alternative hierarchical environment modules organisation supported by EasyBuild and its benefits and implications.
+% %The installation and configuration of EasyBuild will be covered, and basic usage will be presented through demos and guided examples. The main features and capabilities will be outlined and explained, and we will briefly describe an alternative approach to organising environment module files in a hierarchical layout, present the benefits and implications of this approach, and show how EasyBuild supports this.
+% Next we cover how to add support for new software (versions) to EasyBuild, how EasyBuild can be customized to adhere to site policies, and how software installations can be performed in distributed manner.
+% We also compare EasyBuild with similar projects to help attendees decide which is the best approach for them.
+% %The second part of the tutorial will cover some advanced topics including adding support to EasyBuild for building and \emph{TODO MISSING PART}
+% %In this part we also compare with some competing projects  so attendees can decide whether EasyBuild is the best choice for their use case.
+% Extensive guided examples help consolidate the theory in real knowledge.
+% %Special emphasis will be put on the guided examples, where the lessons can be consolidated in real knowledge.
+% Finally, three EasyBuild case studies are presented.
+
+% The tutorial covers motivation, goals and the high-level design of EESSI, as well as the usage through hands-on demos and guided examples. It showcases the main features and capabilities, and also describes the various ways to access EESSI: native, as a production setup in HPC as well as without administrator rights. Next we cover how to different use cases of EESSI, such as portable worksflows, within a CI as well as adding software to EESSI. Troubleshooting access, Testing of the software and Performance evaluation of EESSI will also be covered. Extensive guided examples help consolidate the theory in real knowledge.
+
+\subsection*{EESSI Community + Recognition and Adoption}
+
+The EESSI community has been growing quickly in the last couple of years; the EESSI Slack currently has over 500
+members.
+At Supercomputing 2024, EESSI received the \textbf{HPCWire Readers' Choice Award}
+in the ``Best HPC Programming Tool or Technology"
+category.\footnote{\href{https://www.eessi.io/docs/blog/2024/09/20/hpcwire-readers-choice-awards-2024/}{https://www.eessi.io/docs/blog/2024/09/20/hpcwire-readers-choice-awards-2024/}}
+
+EESSI has been broadly embraced in the European HPC ecosystem, and is already available on dozens of HPC
+sites, including several of the EuroHPC JU
+supercomputers.\footnote{\href{https://www.eessi.io/docs/systems/}{https://eessi.io/docs/systems}}
+
+In addition, it is currently being integrated in the upcoming \textbf{EuroHPC Federation Platform
+(EFP)}\footnote{\href{https://my-eurohpc.eu}{https://my-eurohpc.eu}},
+as the Federated Software Catalogue that will provide a uniform software stack.
+
+\subsection*{Tutorial scope and organisation}
+
+This tutorial is an introduction to EESSI, covering its motivation, goals, high-level design, and the use cases it
+enables (like portable workflows, usage a CI environment, building software on top of it, etc.).
+Through guided hands-on exercises attendees will get a thorough understanding of the basics,
+and be incentived and empowered to learn more and use it in their own daily workflow.
+
+%The main features and functionalities of EESSI are highlighted, as well as the different ways to access the software stack, such as native installation, use in an HPC
+%production setup, or without administrator privileges.
+%The tutorial also covers various use cases for EESSI, including
+%portable workflows, integration into a CI environment, adding software to the EESSI, and also configuring GPU support.
+%Troubleshooting access, testing the software, evaluating the performance of EESSI and configuring GPU support are also covered.
+%Extensive instructor-led examples are used to put the theoretical knowledge into practice.
+
+% At the \textbf{J\"ulich Supercomputing Centre}, EasyBuild is used on multiple supercomputers and prototypes, including JUWELS and JURECA. We cover the highly customized setup used at JSC, the concept of \emph{build stages} used to structure the module
+% system, and tools like EasyBuild hooks, a developer module and user installations, which facilitate collaboration on the software stack by over 30 experts.
+
+% \textbf{LUMI}, a EuroHPC JU pre-exascale system, is an HPE Cray EX system with AMD Instinct GPUs.
+% We will outline why EasyBuild was selected for LUMI, and explain how
+% the setup is focused on empowering users to create their own project software environment on top of the main stack,
+% with the help of a distributed support team. In addition, we will show how EasyBuild
+% integrates with the HPE Cray Programming Environment, and cover why and how the LUMI project maintains
+% its own versions of toolchains and develops many LUMI-specific EasyBuild build recipes.
+
+%We will conclude by showing how EasyBuild is used in large production setups, and provide pointers on how to get in touch with its (growing) community for getting help or to contribute back. Additionally, competing projects will be briefly introduced and compared to EasyBuild, so the attendees can decide whether EasyBuild is the best choice for their use case.
+% KH: OK, fixed \comment{MG: ``with the respective communities'' $\rightarrow$ ``with its (growing) user community''?}
+
+%\paragraph{Expected attendance}
+%Previous events related to the tutorial topic we (co-)organized were well attended. The \emph{``Getting Scientific Software Installed"} Birds-of-a-Feather sessions at SC'13, ISC'14 and SC'14 were well attended, with 74, 40, and over 100~attendees, respectively. The 1st HPC User Support Tools (half-day) workshop we co-organized at SC'14, where a paper on EasyBuild and Lmod entitled \emph{``Modern Scientific Software Management Using EasyBuild and Lmod"} was presented, was attended by about 60 people. The recent 2nd EasyBuild User Meeting had 35 attendees as well as remote participants in the US, Canada, Europe and Australia {\bf not verified!}.
+
+%Based on this, the relevance of the topic to SC'17 attendees (see above), and the feedback we get from the EasyBuild/Lmod communities and other interested parties, we expect this tutorial to be well attended too. We strongly believe an attendance of 40-50 people is likely.
+
+%\paragraph{Ensuring cohesion}
+%We will provide a single cohesive set of slides that covers the entire tutorial. This will be backed up by extensive documentation on the EasyBuild and Lmod documentation pages (\url{http://easybuild.readthedocs.io}, \url{http://lmod.readthedocs.io}). Additionally, a prepared virtual machine image---or access to an AWS instance---will be made available, which will be used during the tutorial for the hands-on sessions.
+
+
+%\paragraph{Previous talks and tutorials, and update for SC'17}
+% EasyBuild has been presented at SC and ISC BoFs (\emph{Getting Scientific Software Installed} in SC'13, SC'14, ISC'14,
+% SC'15, SC'18, and SC'19) and Workshops (PyHPC'12, HUST'14, and HUST'16). This tutorial was also presented
+% (fully online, half-day) at ISC'21 which was well attended with over 25 participants and in-person (half-day) at ISC'22 with about 20 participants.
+% The feedback and attendance has always been positive, which is the primary motivation for this tutorial proposal. The organisers have been actively training user support staff and administrators on EasyBuild in various events in the US and Europe since 2011.
+
+The tutorial organisers have successfully and extensively worked together on several presentations,
+events, and hands-on tutorials and workshops on the topic under consideration several times in recent years.
+A common template
+%will be created to guarantee
+will guarantee
+a coherent visual appearance, and using our previous experience, we will provide high-quality content and materials.
+Moreover, the presenters have experience in organising tutorials in the context of SC and ISC, which helps to understand
+%what is expected
+expectations
+and how to structure the material
+to help ISC attendees to get the most out of it.

+%\comment{KH: Based on attendance at user meetings (and Spack tutorials), I think an estimated attendance of 50-100 people at ISC'19 is reasonable.

+%\comment{MG: 50-100 is a lot for ISC, I would say. The overall number of tutorial attendees is much lower than at SC, and the audience is also a bit different. I would probably say 20-50 -- and if the room in the end is overfull...}

+%KH: So you would go with 20-50? Is that ambitious enough?
+%MG: I think so. Attendance is lower than at SC. And more business people...
+%KH: I'm OK with 20-50, so let's go with that...
+%MG: With my initial comment, I wanted to point out that these sections (target audience, percentage, etc.) are expected as part of the tutorial proposal...  So where should we put it?
+%KH: the form ask you to pick 20-50 or 50-80, I don't think it needs to go in the PDF (but we can add it there, sure). After the "Travel support" section?
+%MG: Well, at some places it suggests to copy from the proposal ;)
+%KH: Let's add a small "Expected attendance" section, mentioning 20-50 + motivation for that number (based on attendance at user meetings (50+), PRACE tutorial ~30 I think in 2017), etc.)

+A significant portion of the tutorial time is used for guided examples and hands-on,
+as they are fundamental to exposing the benefits of EESSI.
+This highlights the practical nature of the tutorial.
+Before each example session the theoretical concepts are explained through a consistent set of presentation materials.
+The guided examples will be carried out in a pre-configured environment on virtual machines in the Cloud that can be
+accessed by the
+attendees from their laptops using SSH or a standard internet browser.
+%The examples cover accessing EESSI in different ways such as native, in a production HPC setup as well as inside
+%containers, the use cases of EESSI, adding support for new software to EESSI, troubleshooting, GPU support, selected
+%advanced features, and how to contribute to EESSI.
+% Each example builds on the previous one and hence also showcases a typical workflow.
+%The guided examples will happen mostly in the proximity of a coffee break allowing the attendees to continue
+%a bit during the coffee break should they want to and ensuring the maximum benefit from the tutorial.
+
+The presentation material for this tutorial is based on previous tutorials, for example the EESSI webinar series
+from May-June~2025 (slides + recordings available at
+\url{https://eessi.io/docs/training-events/2025/webinar-series-2025Q2}).
+
+It should be noted that even though this tutorial has never been presented at ISC, all the authors have extensive
+experience in other tutorials and workshops, both inside and outside the ISC and SC conference series, and both
+in-person and through online webinars.
+Additionally, they engaged in other collaborative efforts within the EESSI and EasyBuild community, like hackathons.
+Providing coherent and streamlined tutorial is well within the organisers' experience.
+
+% This tutorial was presented in the half-day format at ISC'22
+% see \url{https://easybuilders.github.io/easybuild-tutorial/2022-isc22}.
+% The authors have extensive experience in other tutorials and workshops,
+% and are involved in other collaborative efforts within the EasyBuild community.
+% Providing a coherent and streamlined tutorial is well within the authors' experience.
+
+
+%The guided examples sessions provided in this tutorial are fundamental to exposing the benefits of EasyBuild. The attendees will be incrementally walked through an example which they can choose to repeat it for themselves in a prepared environment (supported by the tutorial team). The set of examples are structured sequentially, building on top of each other to follow the typical workflow for a user. Detail will be gradually incremented, with each example exposing deeper capabilities, ensuring that all the attendees learn the concepts in an organised and clear way.
+
+%The examples will be carried out in pre-configured environments available online and accessed using the attendees laptops via SSH. They will cover installation and configuration of EasyBuild, basic EasyBuild usage, adding support for new software to EasyBuild, and how to contribute to the project. The guided examples will happen mostly in the proximity of the coffee break, allowing scope for attendees to use that time should they want to, ensuring the maximum benefit for the tutorial.
+
+%Half of the tutorial time will be focused on the guided examples, highlighting the practical nature of the tutorial.
+%Before each guided example session the theoretical concepts will be explained using a consistent set of slides. The
+%tutorial contents will be (loosely) based on the tutorial that was given at the PRACE VI-SEEM 2017 Spring School (see
+%\url{http://users.ugent.be/~kehoste/EasyBuild_20170425_PRACE_Spring_School.pdf}, relevant subset uploaded to the
+%Linklings submission system), where the presentation material will be updated to focus on EasyBuild, reflect recent
+%changes in EasyBuild, include guided examples, and integrate with the EasyBuild documentation hosted at
+%\url{https://docs.easybuild.io}.

+%
+%\subsection*{Scope}
+%
+%Building (scientific) software from source code is preferred in an HPC setting
+%where performance is critical. Due to increasing diversity of HPC users, the adoption of community codes and the expansion of the typical application software stack (e.g., libraries for MPI, linear algebra functions, solvers, I/O libraries, hardware abstraction layers, accelerator frameworks,\ldots) delivering a reliable, optimised build becomes increasingly complex. Further complicating matters is that application users often require reproducibility of this same software stack between architectures since they may be using a number of different HPC sites at once.
+%
+%Ensuring an optimally performing build of an application across architectures places an enormous burden firstly on the development team of the application itself and then on HPC user support teams to reproduce this build in their own unique environments. Application users and developers also frequently have customisations of applications for their own use case, requiring them to also shoulder this burden across multiple sites.
+%
+%In addition, an HPC workflow or set of HPC tools can easily rely on conflicting versions or configurations of the same libraries. An adequate solution for this (in common use in HPC environments) is the concept of module files. However, most tools available for consuming these module files and setting up the user environment based on them have their shortcomings and problems, and are frequently no longer actively maintained or developed for increasingly complex hardware environments.
+%
+%This tutorial covers two open-source tools that aim to tackle these issues: \textbf{EasyBuild}, a software build and installation framework that can address the needs of the developer, the user and the user support teams; and \textbf{Lmod}, a modern and
+%feature-rich modules tool.
+%
+%\subsection*{EasyBuild (\url{http://hpcugent.github.io/easybuild})}
+%
+%\textit{EasyBuild} eases the often difficult task of building and installing (scientific)
+%software, by providing a framework with which this task can be automated with a limited
+%amount of work. It also serves as a platform for collaboration, enabling a community
+%that works together by sharing implementations of build-and-install procedures and
+%specifications. It can be used to install multiple versions of applications and
+%libraries side-by-side, by installing them to a dedicated installation prefix and generating
+%corresponding module files. EasyBuild features a plug-in architecture w.r.t.\
+%support for software packages, compilers, and libraries (MPI, BLAS, LAPACK, etc).
+%
+%The EasyBuild framework is written in Python, and provides functionality commonly
+%required when building and installing software. Generic or application-specific
+%build-and-install procedures can be implemented in a concise way, and can be easily shared with
+%others. As such, it is a very powerful and valuable tool for both user support teams
+%and end users of HPC infrastructure, to efficiently deal with the often error-prone
+%and time-consuming task of getting scientific software installed (correctly).
+%
+%\subsection*{Lmod (\url{https://www.tacc.utexas.edu/research-development/tacc-projects/lmod})}
+%
+%\textit{Lmod} is a modern replacement for the well-established (Tcl-based) Environment
+%Modules system.  Its main goal is to provide users easy access
+%to their (scientific) software stack, without hindering experts.  Lmod
+%implements the system admins (or in our case the EasyBuild) point of view about how the software
+%stack and its components relate to each other.  It is the handshake
+%between the software stack installers and end users, and delivers to the users
+%the ability to configure and manage their working software stack
+%while benefiting from the hard work and disciplined building of the
+%system.  Lmod is feature-rich, well supported, continuously enhanced,
+%mostly compatible with the traditional Tcl-based environment modules tool, and is backed
+%by a vibrant community.
+%
+%Lmod like other user environment management systems allows users to
+%``load'' modules of their choosing to access compilers, MPI stacks,
+%applications and libraries and also unload/reload as necessary to
+%meet their software needs, next to other more advanced features that make
+%it a powerful and flexible alternative to other established module tools.

+\subsection*{Outline}
+
+We believe that a half-day format would be most appropriate for this tutorial, as it would allow ample time for guided
+examples and hands-on practice, in addition to providing a comprehensive overview of EESSI. The tutorial outline for the half-day format is included below.
+
+% We prefer a full-day format for this tutorial, since this allows for spending sufficient time
+% on guided examples and hands-on, as well as an in-depth look in EESSI. If necessary we can also
+% present a condensed version in a half-day format.
+% 
+% The tutorial outline for both the full-day and half-day formats is included below.
