+### Flags
+
+There are multiple optional flags that can be used with the `oco` command:
+
+#### Use Full GitMoji Specification
+
+Link to the GitMoji specification: https://gitmoji.dev/
+
+This flag can only be used if the `OCO_EMOJI` configuration item is set to `true`. This flag allows users to use all emojis in the GitMoji specification, By default, the GitMoji full specification is set to `false`, which only includes 10 emojis (🐛✨📝🚀✅♻️⬆️🔧🌐💡).
+This is due to limit the number of tokens sent in each request. However, if you would like to use the full GitMoji specification, you can use the `--fgm` flag.
+
+```
+oco --fgm
+```
+
+#### Skip Commit Confirmation
+
+This flag allows users to automatically commit the changes without having to manually confirm the commit message. This is useful for users who want to streamline the commit process and avoid additional steps. To use this flag, you can run the following command:
+
+```
+oco --yes
 ```
