+# Automatic tpm installation
+
+One of the first things we do on a new machine is cloning our dotfiles. Not everything comes with them though, so for example `tpm` most likely won't be installed.
+
+If you want to install `tpm` and plugins automatically when tmux is started, put the following snippet in `.tmux.conf` before the final `run '~/.tmux/plugins/tpm/tpm'`:
+
+```
+if "test ! -d ~/.tmux/plugins/tpm" \
+   "run 'git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm && ~/.tmux/plugins/tpm/bin/install_plugins'"
+```
