+
+## Test and Create Release Archives
+
+### GitHub Actions Automation
+
+The github workflow:
+
+    .github/workflows/dist.yaml
+
+will do this automatically for you.
+
+#### .github/workflows/dist.yaml
+
+This workflow will create release archives (`tar.gz` and `zip`).
+
+### Manually
+
+Make sure you have a clean git repository (no changed files).
+The following process will clone your current git directory.
+
+This will need the docker image `yamlio/libyaml-dev`.
+You can either pull it, or create it yourself:
+
+    make docker-build
+
+### Create dist archives
+
+Run:
+
+    make docker-dist
+
+It will run `make dist` in the container to create a tarball written to
+`pkg/docker/output`.
+It will also create a zipfile.
+
+## Update master
+
+    git merge release/0.x.y
+    git tag -a 0.x.y
+    # <Editor opens>
+    # Paste the corresponding entry from the Changes file
+    # Look at an earlier release for how it should look like:
+    #   git show 0.2.3
+    git push origin master 0.x.y
+
+## Create a GitHub release
+
+Go to "Releases" and click on "Draft a new release".
+
+Fill in the tag you just created in the previous step.
+
+Fill in the release title: v0.x.y
+
+Paste the changelog into the description field.
+
+Upload the tar.gz and .zip file.
+
+You can "Save draft" and publish later, or directly click on "Publish release".
+
+## Update pyyaml.org
+
+See <https://github.com/yaml/pyyaml.org/blob/master/ReadMe.md>.
