 ## Usage
 
-Choose the Module, Function, and Arity of the function you want to profile, click "Flame On", and then trigger the function (e.g. make a web request in a new tab). Note that for Elixir modules, you will need to prefix them with `Elixir`, e.g. `Elixir.Phoenix.Controller`, while Erlang modules take simply the erlang module name, e.g. `cowboy_handler`. The default values of `cowboy_handler`/`execute`/`2` are the best way to capture a standard Phoenix Controller DeadView request or the DeadView request that kicks off a LiveView request.
