+            **Stable release - ${{ steps.version.outputs.version }}**
+            This is a fork of the [Havoc](https://github.com/furrtek/portapack-havoc/) firmware, which itself was a fork of the [PortaPack](https://github.com/sharebrained/portapack-hackrf) firmware, an add-on for the [HackRF](http://greatscottgadgets.com/hackrf/). Please check the [readme](https://github.com/eried/portapack-mayhem/blob/master/README.md) for details.
+            ## Release notes
+            ###  Revision (${{ steps.version.outputs.version }}):
+            ${{ steps.changelog.outputs.content }}
+            
+            **Full Changelog**: https://github.com/eried/portapack-mayhem/compare/${{ steps.past_version.outputs.past_version }}...${{ steps.version.outputs.version }}
+
+            ## Installation
+            Check the [wiki](https://github.com/eried/portapack-havoc/wiki/Update-firmware) for details how to upgrade. 
+
+            ### MicroSD card files
+
+            For certain functionality, like the world map, GPS simulator, and others you need to uncompress (using [7-zip](https://www.7-zip.org/download.html)) the files from `mayhem_vX.Y.Z_COPY_TO_SDCARD.zip` to a FAT32 formatted MicroSD card.
