+## How to use
+
+The offical image (AMD64 only) is [here](https://hub.docker.com/r/gitlab/gitlab-ce/).
+
+The following is an example of how to use this image.
+
+```bash
+docker run \
+  --detach \
+  --restart unless-stopped \
+  --name gitlab-ce \
+  --privileged \
+  --memory 8G \
+  --publish 22:22 \
+  --publish 80:80 \
+  --publish 443:443 \
+  --publish 127.0.0.1:8181:8181 \
+  --hostname gitlab.example.com \
+  --env GITLAB_ROOT_PASSWORD="YourPasswordHere" \
+  --env GITLAB_OMNIBUS_CONFIG=" \
+    registry['enable'] = false; \
+    GITLAB_OMNIBUS[your_other_configs] = here; "\
+  --volume /srv/gitlab-ce/conf:/etc/gitlab:z \
+  --volume /srv/gitlab-ce/logs:/var/log/gitlab:z \
+  --volume /srv/gitlab-ce/data:/var/opt/gitlab:z \
+  yrzr/gitlab-ce-arm64v8:latest
+```
+
+## Redis problem
+
+Redis cannot start with its default config on ARM64, which stops gitlab-ce from starting. You have to change the setting manually on a fresh install or an upgrade and then restart gitlab-ce.
+
+```bash
+# change the path to your redis.conf
+echo "ignore-warnings ARM64-COW-BUG" >> /srv/gitlab-ce/data/redis/redis.conf
+# restart docker container
+docker restart gitlab-ce
+```
