+# Docker - GitBucket
+A simple docker-compose file that can be used to create a *GitBucket* container on SBCs.
+
+## Requirements
+__CPU Architecture:__ ARM64 (Use the official image for AMD64)<br>
+__RAM:__ At least 256 MiB
+
+## Remarks
+This container is not intended to be used with an external database and forces *GitBucket* to use a local DB.<br>
+However, it should be relatively easy to use an external one if you change the `DATABASE_URL` environment variable.
+
+## Building
+In order to build this container, all you have to do is to clone this repository and run `docker-compose up`.
+
+## Configuration
+TODO.
+
+## License
+[License](LICENSE)
+
+This license does not apply to *GitBucket*, *Java* and any of the other applications used by this container.
