 This directory hosts its implementation. It reads into `bsconfig.json`, uses some BS/OCaml/Reason-specific logic, and generates a [ninja](https://ninja-build.org) build file then calls `ninja` on it. So much of the incremental build and perf work is delegated to Ninja.
 
-There's a `templates/` subdirectory. It's the thing shown when you do `bsb -themes`. To generate a template for the user, it basically picks the chosen template from `templates/` and copy pastes it into the destined user directory while substituting some strings in those templates, like `${bsb:proj-version}` in the `package.json`s. The copy-pasting of folders isn't actually done naively through a call to unix `cp`. It's cleverly achieved through something called ocamlres. Please see more descriptions in `pack-templates.sh`.

-When adding/editing a template the script needs to be rerun to update the relevant parts in `bsb_templates.ml`. The script uses [`ocamlres`](https://github.com/OCamlPro/ocp-ocamlres), a tool for embedding files inside ocaml executables. You will need to install it with [`opam`](https://opam.ocaml.org/doc/Install.html), ocaml package manager. Follow the [instructions](https://opam.ocaml.org/doc/Install.html) to install `opam`, if you haven't installed it yet. To install `ocp-ocamlres` run:
-
-```sh
-opam install ocp-ocamlres
-```
