that contain the included files. Users must also have the [permission](../user/permissions.md#job-permissions)
to run CI/CD jobs in the same projects.
### "The parsed YAML is too big" message
This message displays when the YAML configuration is too large or nested too deeply.
YAML files with a large number of includes, and thousands of lines overall, are
more likely to hit this memory limit. For example, a YAML file that is 200kb is
likely to hit the default memory limit.
To reduce the configuration size, you can:
- Check the length of the expanded CI/CD configuration in the pipeline editor's
[merged YAML](pipeline_editor/index.md#view-expanded-configuration) tab. Look for
duplicated configuration that can be removed or simplified.
- Move long or repeated `script` sections into standalone scripts in the project.
- Use [parent and child pipelines](pipelines/parent_child_pipelines.md) to move some
work to jobs in an independent child pipeline.
On a self-managed instance, you can [increase the size limits](../administration/instance_limits.md#maximum-size-and-depth-of-cicd-configuration-yaml-files).
