+### Flags
+There are multiple optional flags that can be used with the `oco` command:
+
+#### Use Full GitMoji Specification
+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.
