 # mirror
 
-Docker images mirroring project.
+Docker images mirroring project.
+
+This thing appears after constant inability of Gitlab developers to mitigate
+Docker Hub ratelimiting shit.
+
+Feel free to use and re-use these images and this mirrorer.
+
+If it helps you much - please, [donate](https://paypal.me/pztrn)
+
+## How to use
+
+This script assumes that you are already logged in into Gitlab Registry.
+
+### In CI
+
+Ensure to add global `before_script`:
+
+```
+before_script:
+  - docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
+```
+
+## Adding new image
+
+If you decided to use my mirrors and want to mirror some image - please make an
+MR with image name be exactly same as in other files in `images` directory.
