 # Important:
 
 Code _is_ considered stable and it shouldn't have any major issues. However, MunkiAdmin is not feature-complete so be prepared to see bugs. If you decide to run this on a production repo, make sure your backups are current or you have some other methods for going back in time. I'm using git version control on my munki repositories so I'll always know what was changed.

+# Donations
+
+There's no need to donate, the app is free to use and I'm just happy it's useful to other admins. If you absolutely want to support the development of these tools, you should first go and see a Disney movie of your choice (because Munki is an open source project from [Walt Disney Animation Studios](https://www.disneyanimation.com/open-source/) and MunkiAdmin simply wouldn't exist without it). After that, if you're still up for it, you can [buy me a coffee](https://www.buymeacoffee.com/hjuutilainen).
