+## Publishing package
+
+### Beta versions
+
+Each commit to `dev` branch will result in publishing a new version of library
+tagged `beta`. Versions names are based on commit SHA, e.g. 
+`foris@0.1.0-d9073aa4.0`.
+
+### Preparing a release
+
+1. Crete a merge request to `dev` branch with version bumped
+2. When merging add `[skip ci]` to commit message to prevent publishing
+unnecessary version
+3. Create a merge request from `dev` to `master` branch
+4. New version should be published automatically
