 ## External dependencies
 
+### `packbeam`
+
+AtomVM depends on `packbeam`. It is used to pack beams as well as assets into AtomVM pack format, `.avm`. `packbeam` source code is downloaded automatically by `rebar3` from `hex` mirrors, and it is then escriptized.
+
+It is possible to use a local copy of `packbeam` source code by setting `PACKBEAM_PATH` variable to a path to a source checkout of [`atomvm_packbeam`](https://github.com/atomvm/atomvm_packbeam) when invoking CMake.
+
 ### `uf2tool`
 
-AtomVM depends on `uf2tool`. It is used to pack both native and Erlang/Elixir/Gleam code for RP2. uf2tool is downloaded automatically by `rebar3` from `hex` mirrors.
