 1. Build and test locally.
 
 2. Bump version in `build.sbt`, run `sbt package`. We also want a release on github and the course home page aligned with the release on Sonatype Central. Therefore You should also:
+  - Don't forget to uppdate the `rootdoc.txt` file with current version information and package contents etc.: https://github.com/lunduniversity/introprog-scalalib/blob/master/src/rootdoc.txt
   - commit all changes and push and *then* create a github release with the packaged jar uploaded to https://github.com/lunduniversity/introprog-scalalib/releases
   - Publish the jar to the course home page at http://cs.lth.se/lib using  `sh publish-jar.sh`
   - Publish updated docs to the course home page at http://cs.lth.se/api using script `sh publish-doc.sh`
   - Copy the introprog-scalalib/src the workspace subdir at https://github.com/lunduniversity/introprog to enable eclipse project generation with internal dependency of projects using `publish-workspace.sh`. Then run `sbt eclipse` in that repo and the `package.sh` script to create `workspace.zip` etc. TODO: For the future it would be nice to have another repo introprog-workspace and factor out code to that repo and solve the problem of dependency between latex code and the workspace.
 
 3. In `sbt` run `publishedSigned`

+7. Download the staged jar by clicking on it and selecting the *Artifact* tab to the right and click the Repository Path to download. Save it e.g. in `tmp`.
 
 8. Verify that the staged jar downloaded from sonatype works by running `scala -cp introprog-xxx.jar` and in REPL e.g. `val w = new introprog.PixelWindow`. The reason for this step is that there has been incidents where the uploading has failed and the jar was empty. A published jar can not be retracted even if corrupted according to Sonatype policies.
