+### Ignore files
+You can ignore files from submission to OpenAI by creating a `.opencommitignore` file. For example:
+
+```ignorelang
+path/to/large-asset.zip
+**/*.jpg
+```
+
+This is useful for preventing opencommit from uploading artifacts and large files.
+
+By default, opencommit ignores files matching: `*-lock.*` and `*.lock`
+
 ## Git hook
 
 You can set OpenCommit as Git [`prepare-commit-msg`](https://git-scm.com/docs/githooks#_prepare_commit_msg) hook. Hook integrates with you IDE Source Control and allows you edit the message before commit.
