 We're a Rails app, and we use [Webpacker][webpacker] to manage some of our
 JavaScript.

+# Starting the application (advanced)
+
+To have additional control in your local environment, you might prefer using an
+advanced setup to start the application by using [Overmind][overmind].
+
+The prerequisite is to install [Overmind][overmind], a process manager which
+takes advantage of [tmux][tmux].
+
+This will allow you to launch all your app's processes in the same terminal, navigate the logs
+of each service separately, restart each service separately and have a better
+debugging experience.
+
+After installing [Overmind][overmind], launch the application:
+
+```shell
+overmind s -f Procfile.dev
+```
+
+## Debugging the Rails application
+
+[Overmind][overmind] lets you easily step through the Rails application in a
+debugging session.
+
+Using the `pry` gem, you can add a `binding.pry` to set a breakpoint in the method you're trying to
+debug; the application will halt its execution there. You can then connect
+to the web server by opening a separate terminal window and typing:
+
+```shell
+overmind c web
+```
+
+This will open up a [tmux][tmux] window pane at the debugging statement
+position, which will look something like this:
+
+```ruby
+pry(#<Admin::AdminPortalsController>)> whereami
+
+From: /forem/app/controllers/admin/admin_portals_controller.rb:8 Admin::AdminPortalsController#index:
+
+    5: def index
+    6:   a = "Hello debugger"
+    7:   binding.pry
+ => 8: end
+```
+
+## Inspecting the logs of each service
+
+Overmind launches the various services required for our local setup: `web` (the
+Rails web server), `webpacker` (the server managing JavaScript) and `sidekiq`
+(the server managing the asynchronous queue).
+
+If, for example, you want to inspect just the Sidekiq logs, you can open a
+separate terminal window to look at those logs specifically:
+
+```shell
+overmind c sidekiq
+```
+
+This will open a `tmux` console, which will allow you to browse _only_ the Sidekiq logs.
+
+There are also some handy `tmux` shortcuts that you may find useful.
+
+* The shortcut `C-b [` (_Control-b-open square bracket_) activates "scroll
+mode", which allows you to use the arrows up and down and inspect the logs.
+* The shortcut `q` deactivates "scroll mode".
+
+Please refer to [tmux][tmux] documentation for more information around `tmux` configuration and for additional
+shortcuts.
