+### prune
+
+Remove installed plugins that are no longer referenced in your `quartz.config.yaml`. This is useful for cleaning up after removing plugin entries from your configuration.

+```shell
+npx quartz plugin prune

+Use `--dry-run` to preview which plugins would be removed without making changes:

+npx quartz plugin prune --dry-run

+### resolve
+
+Install plugins that are listed in your `quartz.config.yaml` but missing from the lockfile. This is the inverse of `prune` — it ensures your installed plugins match your configuration.

+### Cleaning Up Unused Plugins

+If you've removed plugins from your config and want to clean up leftover files:
+
+```shell
+npx quartz plugin prune --dry-run  # preview first
+npx quartz plugin prune            # remove orphaned plugins
+```
+
+### Setting Up from Config
+
+When setting up on a new machine or in CI, resolve any plugins referenced in your config that aren't yet installed:
+
+```shell
+npx quartz plugin resolve
+```
+
+Both `prune` and `resolve` will fall back to `quartz.config.default.yaml` if no `quartz.config.yaml` is present.

 ## Interactive Mode
 
 Running the plugin command without any subcommand will launch the [[cli/tui|TUI]], which provides a visual interface for all these operations.
