Gitea `1.11.0` and above includes template repositories, and one feature implemented with them is auto-expansion of specific variables within your template files.
To tell Gitea which files to expand, you must include a `template` file inside the `.gitea` directory of the template repository.
Gitea uses [gobwas/glob](https://github.com/gobwas/glob) for its glob syntax. It closely resembles a traditional `.gitignore`, however there may be slight differences.
