+## Continuous integration
+
+### Build, test and deploy
+Swagger Codegen uses Github actions to run jobs/checks building, testing and deploying snapshots on push and PR events.
+
+These github actions are configured in `.github/workflows`:
+
+* maven-master.yml : Build Test Deploy master
+* maven-master-pulls.yml Build Test PR
+
+
+These actions use available actions in combination with short bash scripts.
+
+### Release
+
+Releases are semi-automated and consist in 2 actions using available public actions in combination with bash and python scripts.
+**TODO**: Python code is used for historical reasons to execute GitHub APIs calls, in general a more consistent environment would
+be more maintainable e.g. implementing a custom JavaScript or Docker Container GitHub Action and/or a bash only script(s).
+
+#### Workflow summary
+
+1. execute `prepare-release-master.yml` / `Prepare Release Master` for `master` branch
+1. check and merge the Prepare Release PR pushed by previous step. Delete the branch
+1. execute `release-master.yml` / `Release Master` for `master` branch
+1. check and merge the next snaphot PR pushed by previous step. Delete the branch
+
+#### Prepare Release
+
+The first action to execute is `prepare-release-master.yml` / `Prepare Release Master` for master branch.
+
+This is triggered by manually executing the action, selecting `Actions` in project GitHub UI, then `Prepare Release Master` workflow
+and clicking `Run Workflow` 
+
+`Prepare Release Master` takes care of:
+
+* create release notes out of merged PRs
+* Draft a release with related tag
+* bump versions to release, and update all affected files
+* build and test maven
+* push a Pull Request with the changes for human check.
+
+After the PR checks complete, the PR can me merged, and the second phase `Release Master` started.
+
+#### Release
+
+Once prepare release PR has been merged, the second phase is provided by `release-master.yml` / `Release Master` actions for master branch.
+
+This is triggered by manually executing the action, selecting `Actions` in project GitHub UI, then `Release Master` workflow
+and clicking `Run Workflow`
+
+`Release Master` takes care of:
+
+* build and test maven
+* deploy/publish to maven central
+* publish the previously prepared GitHub release / tag
+* build and push docker image
+* deploy/publish docker image to docker hub
+* push PR for next snapshot
+
+
+
+### Secrets
+
+GitHub Actions make use of `Secrets` which can be configured either with Repo or Organization scope; the needed secrets are the following:
+
+* `APP_ID` and APP_PRIVATE_KEY`: these are the values provided by an account configured GitHub App, allowing to obtain a GitHub token
+different from the default used in GitHub Actions (which does not allow to "chain" actions).Actions
+
+The GitHub App must be configured as detailed in [this doc](https://github.com/peter-evans/create-pull-request/blob/master/docs/concepts-guidelines.md#authenticating-with-github-app-generated-tokens).
+
+See also [here](https://github.com/peter-evans/create-pull-request/blob/master/docs/concepts-guidelines.md#triggering-further-workflow-runs)
+
+* `OSSRH_GPG_PRIVATE_KEY` and `OSSRH_GPG_PRIVATE_PASSPHRASE` : gpg key and passphrase to be used for sonatype releases
+GPG private key and passphrase defined to be used for sonatype deployments, as detailed in
+https://central.sonatype.org/pages/working-with-pgp-signatures.html (I'd say with email matching the one  of the sonatype account of point 1
+
+* `MAVEN_CENTRAL_USERNAME` and `MAVEN_CENTRAL_PASSWORD`: sonatype user/token
+
+* `GRADLE_PUBLISH_KEY` and `GRADLE_PUBLISH_SECRET`: credentials for https://plugins.gradle.org/
