+# Connect To Individual Overmind Processes Via tmux
+
+A common `Procfile.dev` in a Rails project might look something like this.
+
+```
+web: bin/rails server -p $PORT
+vite: bin/vite dev
+worker: bundle exec good_job start
+```
+
+Instead of starting up each process that needs to be running for development to
+work, I can instead run a tool that reads the procfile and sets it all up for me
+-- like `overmind`.
+
+```bash
+❯ overmind start -f Procfile.dev
+```
+
+What's cool about `overmind` is that it starts its own `tmux` session and then
+runs each of these processes in its own window.
+
+I can connect to any one of them by name with `overmind connect <name>`. Or I
+can connect to the session defaulting to the first window with just `overmind
+connect`.
+
+If I need to see what is going on with my background jobs, I'll run:
+
+```bash
+❯ overmind connect worker
+```
+
+This behaves like any other tmux session, so I can use my prefix key (`ctrl-z`
+in my case) to access tmux-specific keybindings. Most notably, once I'm done
+looking, I'll want to hit `ctrl-z d` to detach from the session.
+
+I'm already using tmux as my daily driver which means its easy for me to end up
+in a nested tmux session if I connect while already in my development session.
+To help with that, I set up [a forwarding
+prefix](set-up-forwarding-prefix-for-nested-session.md).
