+To be able to install the plugin, just hit <kbd>prefix</kbd> + <kbd>I</kbd>. A fancy installation
+process will appear. Follow the described steps, and you should now be able to use the plugin!

+Note: If you always choose the same method during the installation process (Ex. Because you use this
+plugin in an immutable environment), you can pass the `TMUX_THUMBS_INSTALLATION` environment variable
+to choose your desired approach. Valid values for this environment variable are `compile` or `download`.
