 ## Build and run tests locally
 
 The software is written in [Scala](https://scala-lang.org/) and is built with [SBT](http://www.scala-sbt.org/).
 
-The project is built and released for Scala versions 2.12 and 2.13.
-To compile and test both versions run `sbt +test`.

 ## Performing a release (for project maintainers)
 
-1. Follow the [sbt-bintray publishing guidelines](https://github.com/sbt/sbt-bintray#publishing) to ensure you are
-   authenticated with Bintray.  Note that you need to be a member of the `sky-uk` Bintray organization. 
-2. Run `sbt release` to perform the release of the binaries to Bintray.
-3. Check you are happy with the draft publication of the new version [here](https://bintray.com/sky-uk/oss-maven/kafka-topic-loader)
-   and, if so, run `sbt bintrayRelease` to make the new version publicly accessible.
+Merging a PR to master will create a snapshot release in the [Sonatype snapshot repository](https://s01.oss.sonatype.org/content/repositories/snapshots/uk/sky/).
+
+To create a new stable release, you must tag the head of master and push it to Github.
+
+```bash
+git checkout master
+git pull origin master
+git tag -a v$VERSION -m "v$VERSION"
+git push origin v$VERSION
+```
+
+> 💡 The tag **must** start with a `v` followed by the version, e.g. `v1.0.0`
+
+This will trigger the `release` stage of the [travis workflow](./.travis.yml), and push the image to the [Sonatype release repository](https://s01.oss.sonatype.org/content/repositories/releases/uk/sky/).
