 This is a toy system for playing around with autonomous drone/quadcopter simulations, using Elixir.  Right now it is not intended to be used for real drones or to do anything fancy, but maybe someday that will change. It is mostly just a proof-of-concept for building robotics systems using Elixir and the Erlang VM.
 
+# Usage
+
+Easiest to just use [`asdf`](https://github.com/asdf-vm/asdf), for better or for worse.
+
+```
+source ~/.asdf/asdf.whatever
+asdf plugin add erlang
+asdf plugin add elixir
+asdf plugin add elixir-ls
+mix deps.get
+iex -S mix
+```
+
 # Tools
 
  * Build system: mix (required for Nerves, which is worth it)
