+# Admin Features
+
+This page covers features intended for server administrators. These features are primarily available to players with OP permissions.
+
+## Plugin Status (`/lc status`)
+
+View an overview of the plugin's operational status.
+
+```
+/lc status
+```
+
+Displayed information:
+
+- Plugin version (with Git commit hash)
+- Health status (OK / Degraded)
+- Enabled/disabled state of each feature
+- Configuration values (debug mode, update checking, language)
+- Links to GitHub, Modrinth, and documentation
+
+## Spy Mode
+
+Players with the `lunaticchat.spy` permission (default: op) can view all direct messages sent and received on the server.
+
+- Spy players see the original message before romaji conversion
+- Hover text indicates the message is a spy message
+- Spy players themselves are not included in the normal sender/recipient list
+
+## Channel Bypass
+
+Players with the `lunaticchat.channelbypass` permission (default: op) can bypass the following channel restrictions.
+
+- Cannot be kicked or banned
+- Can delete channels even without being the owner
+
+## Update Notifications
+
+When `checkForUpdates` is `true` (default), the plugin checks for new versions at startup. Players with the `lunaticchat.noticeupdate` permission (default: op) receive an update notification when they join the server.
+
+```yaml
+# config.yml
+checkForUpdates: true
+```
+
+## Debug Mode
+
+Setting `debug` to `true` enables verbose plugin logging. This is useful for troubleshooting issues or submitting bug reports.
+
+```yaml
+# config.yml
+debug: true
+```
+
+## Language Setting
+
+You can change the language of messages displayed to players. Plugin logs and console output are not affected and remain in English only.
+
+```yaml
+# config.yml
+language: "ja"   # "en" or "ja"
+```
+
