+# Managing plugins via the command line
+
+Aside from tmux key bindings, TPM provides shell interface for managing plugins
+via scripts located in [bin/](../bin/) directory.
+
+Tmux does not need to be started in order to run scripts (but it's okay if it
+is). If you [changed tpm install dir](../docs/changing_plugins_install_dir.md)
+in `.tmux.conf` that should work fine too.
+
+Prerequisites:
+
+- tmux installed on the system (doh)
+- `.tmux.conf` set up for TPM
+
+### Installing plugins
+
+As usual, plugins need to be specified in `.tmux.conf`. Run the following
+command to install plugins:
+
+    ~/.tmux/plugins/tpm/bin/install_plugins
+
+### Updating plugins
+
+To update all installed plugins:
+
+    ~/.tmux/plugins/tpm/bin/install_plugins all
+
+or update a single plugin:
+
+    ~/.tmux/plugins/tpm/bin/install_plugins tmux-sensible
