 This Xcode project can be used to build [minetest-c55](https://github.com/celeron55/minetest).
 
-Use the branch `delta` if you want to build [minetest-delta](https://github.com/erlehmann/minetest-delta). But that branch is pretty old.
+Fore more information have a look the [official homepage](http://c55.me/minetest/).

+Somebody also reported that he was able to build it with Xcode 3.2.5 under 10.6 using

 ### Commandline
 
-* Run `xcodebuild` in the minetest-mac folder
+### Build for debugging
+
+You probably don't care about correctly set version information and stuff while coding.
+So just run `xcodebuild -target "App Bundle"` in the minetest-mac folder.
+
+### Building for release
+
+`xcodebuild -target "Release Bundle"`
+
+The release version is not very different to the above 'App Bundle'. The important
+difference is, that it contains the proper version strings everywhere. It's set up
+to work on my machine so you may have to modify some build settings in Xcode:
+
+It uses `git describe --tags` to get the version. So the minetest code should reside in
+a git repository. If your `git` doesn't live in `/usr/local/bin/` you have to modify the
+'Version from git' target in the build settings.
