+## Advanced Configuration
+### Managing shell plugins in your own dotfiles
+
+By default, `op plugin init` writes its configuration to `~/.config/op/plugins.sh`
+and manages that file for you. If you'd rather keep your plugin configuration in
+your own dotfiles (for example, tracked in version control), you can define the
+shell functions yourself and source them in your shell's configuration file. 
+
+### Step 1: Define the plugin functions
+Shell functions for each shell should follow this pattern. In this case, 
+
+### bash / zsh
+
+```bash
+gh() {
+  op plugin run -- gh "$@"
+}
+```
+
+### fish
+
+```fish
+function gh --wraps gh --description "1Password shell plugin for GitHub CLI"
+  op plugin run -- gh $argv
+end
+```
+
+### Step 2: Tell `op` your plugins are already configured
+
+Set `OP_PLUGIN_ALIASES_SOURCED=1` so 1Password CLI knows the shell plugins have
+already been set up:
+
+### bash / zsh
+
+```bash
+export OP_PLUGIN_ALIASES_SOURCED="1"
+```
+
+### fish
+```fish
+set -x OP_PLUGIN_ALIASES_SOURCED 1
+```
+
+> **Note:** `op plugin init <plugin>` edits `~/.config/op/plugins.sh` directly and won't update your own dotfiles, so configure plugins manually as shown above.
