+### `hooks`
+
+> Introduced in GitLab 15.6 [with a flag](../../administration/feature_flags.md) named `ci_hooks_pre_get_sources_script`. Disabled by default.
+
+FLAG:
+On self-managed GitLab, by default this feature is not available. To make it available,
+ask an administrator to [enable the feature flag](../../administration/feature_flags.md) named `ci_hooks_pre_get_sources_script`.
+The feature is not ready for production use.
+
+Use `hooks` to specify lists of commands to execute on the runner
+at certain stages of job execution, like before retrieving the Git repository.
+
+**Keyword type**: Job keyword. You can use it only as part of a job or in the
+[`default` section](#default).
+
+**Possible inputs**:
+
+- A hash of hooks and their commands. Available hooks: `pre_get_sources_script`.
+
+#### `hooks:pre_get_sources_script`
+
+> Introduced in GitLab 15.6 [with a flag](../../administration/feature_flags.md) named `ci_hooks_pre_get_sources_script`. Disabled by default.
+
+Use `hooks:pre_get_sources_script` to specify a list of commands to execute on the runner
+before retrieving the Git repository and any submodules. You can use it
+to adjust the Git client configuration first, for example.
+
+**Related topics**:
+
+- [GitLab Runner configuration](https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runners-section)
+
+**Example of `hooks:pre_get_sources_script`**:
+
+```yaml
+job1:
+  hooks:
+    pre_get_sources_script:
+      - echo 'hello job1 pre_get_sources_script'
+  script: echo 'hello job1 script'
+```
+
 ### `image`
 
 Use `image` to specify a Docker image that the job runs in.
