+    <para>
+      In this document and related Nix expressions we use the term
+      <emphasis>Beam</emphasis> to describe the environment. Beam is
+      the name of the Erlang Virtial Machine and, as far as we know,
+      from a packaging perspective all languages that run on Beam are
+      interchangable. The things that do change, like the build
+      system, are transperant to the users of the package. So we make
+      no distinction.

+    <title>Rebar3</title>
+    <para>
+      By default Rebar3 wants to manage it's own dependencies. In the
+      normal non-Nix, this is perfectly acceptable. In the Nix world it
+      is not. To support this we have created two versions of rebar3,
+      <literal>rebar3</literal> and <literal>rebar3-open</literal>. The
+      <literal>rebar3</literal> version has been patched to remove the
+      ability to download anything from it. If you are not running it a
+      nix-shell or a nix-build then its probably not going to work for
+      you. <literal>rebar3-open</literal> is the normal, un-modified
+      rebar3. It should work exactly as would any other version of
+      rebar3. Any Erlang package should rely on
+      <literal>rebar3</literal> and thats really what you should be
+      using too.

+      them. However, that is supported by the
+      <literal>buildMix</literal> and <literal>buildErlangMk</literal> derivations.

-    <para>
-      To make life easier for our users, it makes good sense to go
-      ahead and attempt to build all those packages and remove the
-      ones that don't build. To do that, simply run the command (in
-      the root of your <literal>nixpkgs</literal> repository). that follows.
-    </para>
-    <programlisting>
-$ nix-build -A erlangPackages
-    </programlisting>
-    <para>
-      That will build every package in
