-   The Nix expressions for Elm reside in
-   <filename>pkgs/development/compilers/elm</filename>. They are generated
-   automatically by <command>update-elm.rb</command> script. One should specify
-   versions of Elm packages inside the script, clear the
-   <filename>packages</filename> directory and run the script from inside it.
-   <literal>elm-reactor</literal> is special because it also has Elm package
-   dependencies. The process is not automated very much for now -- you should
-   get the <literal>elm-reactor</literal> source tree (e.g. with
-   <command>nix-shell</command>) and run <command>elm2nix.rb</command> inside
-   it. Place the resulting <filename>package.nix</filename> file into
-   <filename>packages/elm-reactor-elm.nix</filename>.
