+Added an option to scan GitHub for repositories using a new location type `github-discovery`.
+Example:
+
+```yaml
+type: 'github-discovery',
+target:
+   'https://github.com/backstage/techdocs-*/blob/master/catalog.yaml'
+```
+
+You can use wildcards (`*`) as well. This will add `location` entities for each matching repository.
+Currently though, you must specify the exact path of the `catalog.yaml` file in the repository.
