+# Steps to create the release:
+
+1. Manually build and test the new additions
+2. Create a new tag based on:  
+    $ tag=v0.2.1  
+    $ git tag -s "${tag}" -m "${tag}"  
+    $ git push origin "${tag}"  
+
+3. Create the binaries with build cross, they are in dist/
+4. Create the GitHub release, copy the release notes from the previous ones, and adjust as necessary. Upload the binaries created and click publish on the release.
+5. The last step is creating and uploading the docker images. Use make image to create them and then tag them. Keep in mind that there is only 1 image for cortextool in Dockerhub at the moment.
