+## Making a release
+
+Make sure you have permission to publish, by running
+
+    npm access ls-collaborators
+
+While on the `master` branch, switch to a new branch, possibly called `release`:
+
+    git switch --create release
+    npm run make-release-commit
+
+Create a new pull request from this branch. The name of the pull request possibly identical to the commit message.
+
+"Rebase and merge" the pull request.
+
+    git switch master
+    git pull
+
+Where `$VERSION` is the new version, run
+
+    git tag v$VERSION
+
+For example:
+
+    git tag v5.2.4
+
+And then
+
+    git push --tags
+    npm publish
