    - You can setup a "purge" hook to let you invalidate cache when the microblog was updated
- - Deployable with Docker
+ - Deployable with Docker (Docker compose for everything: dev, test and deployment)
+ - Focus on testing
+   - Tested against the [official ActivityPub test suite](https://test.activitypub.rocks/) ([ ] TODO submit the report)
+   - CI runs some local "federation" tests
+   - Manually tested against [Mastodon](https://github.com/tootsuite/mastodon)
