 SKCraft Launcher
 ================
 
+This launcher features a powerful package deployment system for 
+Minecraft. We use it to provide updates for our server, and you may 
+find it useful too.
+
+Unlike the previous iteration of the launcher,
+due to time constraints, we have gone back to making launchers suited for
+one server (or one provider), meaning that you will have to modify the
+launcher as necessary and distribute your own .exe, .jar, .app files
+to fit your requirements. However, this is fairly easy to do because
+nearly every string has been translated, and all the important
+properties reside in one single file. See [the 
+relevant page](http://confluence.skcraft.com/display/LAUN/Launcher+Customization) 
+for more information. You are invited to fork this repository on
+GitHub and make the necessary changes.
+
+For the time being, the launcher is no longer a general purpose
+Minecraft launcher.

+
+Architectural Changes from 3.x
+------------------------------
+
+This launcher has gone through two major updates since the days
+of Minecraft Alpha, but the update system (and its features) has been carried
+over between launcher versions. The biggest change from 
+[version 3.x](https://github.com/sk89q/skmclauncher) is perhaps the changeover
+to JSON from XML due to the new requirement that a JSON parsing
+library must be bundled with the launcher (we use Jackson JSON). Prior
+versions of the launcher utilized the JAXB implementation bundled with
+the Java runtime.
+
+Also note that we've decided to bundle additional libraries (notably
+Guava), which brings the file size of the launcher up by a few
+megabytes, which is fairly negligible.
+
+Compiling
+---------
+
+The launcher can be compiled using [Maven](http://maven.apache.org/).
+
+    mvn clean package
+
+If you wish to import the project into an IDE, you must add support for
+Project Lombok.
