+### Using AI-assisted code generators
+
+PRs that include AI-generated content, may that be in code, in the PR
+description or in documentation need to
+
+1. clearly mark the AI-generated sections as such, for example, by
+   mentioning all use of AI in the PR description, and
+2. include proof that you have run the generated code on an actual
+   installation of Nominatim. Adding and excuting tests will not be
+   sufficient. You need to show that the code actually solves the problem
+   the PR claims to solve.

 ## Coding style
 
 Nominatim historically hasn't followed a particular coding style but we
 are in process of consolidating the style. The following rules apply:
 
  * Python code uses the official Python style

+## Releases
+
+Nominatim follows semantic versioning. Major releases are done for large changes
+that require (or at least strongly recommend) a reimport of the databases.
+Minor releases can usually be applied to existing databases. Patch releases
+contain bug fixes only and are released from a separate branch where the
+relevant changes are cherry-picked from the master branch.
+
+Checklist for releases:
+
+* [ ] increase versions in
+  * `src/nominatim_api/version.py`
+  * `src/nominatim_db/version.py`
+  * CMakeLists.txt
+* [ ] update `ChangeLog` (copy information from patch releases from release branch)
+* [ ] complete `docs/admin/Migration.md`
+* [ ] update EOL dates in `SECURITY.md`
+* [ ] commit and make sure CI tests pass
+* [ ] test migration
+  * download, build and import previous version
+  * migrate using master version
+  * run updates using master version
+* [ ] prepare tarball:
+  * `git clone --recursive https://github.com/osm-search/Nominatim` (switch to right branch!)
+  * `rm -r .git* osm2pgsql/.git*`
+  * copy country data into `data/`
+  * add version to base directory and package
+* [ ] upload tarball to https://nominatim.org
+* [ ] prepare documentation
+  * check out new docs branch
+  * change git checkout instructions to tarball download instructions or adapt version on existing ones
+  * build documentation and copy to https://github.com/osm-search/nominatim-org-site
+  * add new version to history
+* [ ] check release tarball
+  * download tarball as per new documentation instructions
