+### Using TPM plugins
+
+This configuration now comes with built-in [TPM] support:
+- use the `set -g @plugin ...` syntax to enable a plugin
+- whenever a plugin introduces a variable to be used in `status-left` or
+  `status-right`, you can use it in `tmux_conf_theme_status_left` and
+  `tmux_conf_theme_status_right` variables, see instructions above 👆
+- ⚠️ do not add `set -g @plugin 'tmux-plugins/tpm'`
+- ⚠️ do not add `run '~/.tmux/plugins/tpm/tpm'` to `~/.tmux.conf` or your
+- `~/.tmux.conf.local` copy ← people who are used to alter
+  `.tmux.conf` to add TPM support will have to adapt their configuration
+
+⚠️ The TPM bindings differ slightly from upstream:
+  - installing plugins: `<prefix> + I`
+  - uninstalling plugins: `<prefix> + Alt + u`
+  - updating plugins: `<prefix> + u`
