+This is an example of updating the installer from 22.02 to 23.09.beta.01:
 1. Make sure install4j is not opened
-2. Download the OpenRocket-22.02.beta.05-macOS.dmg file 
-3. Make a read/write .dmg file using the terminal command `hdiutil convert OpenRocket-22.02.beta.05-macOS.dmg -format UDRW -o 22.02.beta.05_rw.dmg`
-4. Enlarge the writable DMG, by first checking the current size: `hdiutil resize 22.02.beta.05_rw.dmg`, e.g. you get 430000 in the 'cur' column, then just resize it to e.g. 500000: `hdiutil resize -sectors 500000 22.02.beta.05_rw.dmg`
-5. Mount the DMG: `hdiutil attach 22.02.beta.05_rw.dmg`
-6. Open the OpenRocket-disk from your desktop and change the app name from 22.02.beta.05 to 22.02 
-7. Copy the .DS_Store to `openrocket/install4j/22.02/macOS_resources` by running the command `cp /Volumes/OpenRocket/.DS_Store openrocket/install4j/22.02/macOS_resources/DS_Store`
+2. Download the OpenRocket-22.02-macOS.dmg file 
+3. Make a read/write .dmg file using the terminal command `hdiutil convert OpenRocket-22.02-macOS.dmg -format UDRW -o 22.02.beta.05_rw.dmg` OR use the `template_dmg_rw.dmg`.
+4. Enlarge the writable DMG, by first checking the current size: `hdiutil resize template_dmg_rw.dmg`, e.g. you get 430000 in the 'cur' column, then just resize it to e.g. 500000: `hdiutil resize -sectors 500000 template_dmg_rw.dmg`

 8. Eject the OpenRocket DMG disk from your desktop (important step)
-9. Delete `22.02.beta.05_rw.dmg`
