+1. [Medley Interlisp for the Newcomer](https://primer.interlisp.org) (also known as the new Medley Primer). An introductory guide to the basics of Interlisp and the Medley environment that doesn't assume prior knowledge of Lisp. Read it in full. Written in 2025, the guide is designed to ease modern users into the system and replace the [old primer](/documentation/Medley-Primer.pdf) published in 1992, now obsolete.
+1. [Medley Basics for Common Lisp users](cl-using). 
 If you are familiar with Common Lisp, this guide points out some differences.
-3. [Using Medley Online](online-using) -- additional introduction primarily for online users
-1. [Medley for the Novice](/documentation/Medley-Primer.pdf) (also known as Medley Primer).  An introductory guide to the basics of Medley such as executing commands, using menus and files, manipulating windows, editing and saving Lisp code, using the development tools, and more. Read it in full. The code in chapter 20 "Free Menus" doesn't work and some illustrations are missing.
 1. [SEdit — The Lisp Editor](https://drive.google.com/file/d/12LW5zCZauJvC63NRMJhjNv5qJkuuCflb/view?usp=sharing). The manual of SEdit, the default Lisp code editor.

 1. [LispCourse notes](https://interlisp.org/documentation/lispcourse.pdf). The notes of a beginner course on the Interlisp environment that goes from the basics of interacting with the system to programming in Lisp. Highly recommended. Skip the sections on printing and the network as modern Medley doesn't fully implement the described functionality. The formatting of the text is partially broken and some sections are missing.
