+# Multi-file running changelog
+
+To avoid merge conflicts in the CHANGELOG.md file we accepted the multi-file running changelog strategy.
+
+*This strategy works for the libnavui-androidauto project too. It works in the `libnavui-androidauto/changelog` directory*
+
+To follow this strategy you should create a `.md` file for every PR. Choose a directory:
+
+- `changelog/unreleased/features` for **Features** changes
+- `changelog/unreleased/bugfixes` for **Bug fixes and improvements** changes
+- `changelog/unreleased/issues` for **Known issues :warning:** changes
+- `changelog/unreleased/other` for other changes
+
+Or you can use the helper script to do it. Just call `python3 scripts/changelog/add_changelog.py -f "I have added something special"` to create a changelog file.
+Call `python3 scripts/changelog/add_changelog.py -h` to get more info.
+
+You can use anything that allow .md format in changelog files.
+
+If you have implemented several features or bugfixes you should describe all of them:
+
+```
+- Description of changes in md format
+- Description of changes in md format also
+```
+
+You can choose any name for your changelog files because the GitHub action will rename files in
+`changelog/unreleased/features` and `changelog/unreleased/bugfixes` directories to `${PR_NUMBER}.md` when you open a PR.
+
+Every push to the main or release branch Assemble changelog GitHub action will be executed:
+
+* collect all files from `changelog/unreleased`
+* assemble the changelog like:
+
+```
+#### Features
+- Feature 1 [#1234](https://github.com/mapbox/mapbox-navigation-android/pull/1234)
+- Feature 2 [#2345](https://github.com/mapbox/mapbox-navigation-android/pull/2345)
+
+#### Bug fixes and improvements
+- Bugfix 3 [#3456](https://github.com/mapbox/mapbox-navigation-android/pull/3456)
+- Bugfix 4 [#4567](https://github.com/mapbox/mapbox-navigation-android/pull/4567)
+
+#### Known issues :warning:
+- Issue 1
+- Issue 2
+
+Some other changes
+```
+
+* write the changelog to the `changelog/unreleased/CHANGELOG.md` file
+
+Every release the release train app will:
+
+* get changelog from `changelog/unreleased/CHANGELOG.md` file
+* add information about dependencies and compile changelog like:
+```
