+# 2004Scape Client
+
+Status: **Completely renamed!** There's no obfuscation or unnamed classes/methods/fields/variables left.
+
+The TeaVM webclient is in the `webclient` branch until it can be made compatible with this new branch: see https://github.com/2004scape/Client/tree/webclient
+
+## Project Structure
+
+`client` - Decompiled client source code. Some class names are original.
+
+`deob-annotations` - OpenRS2 dedobfuscator annotations library. Useful for making the namings of everything reusable if starting again from scratch or comparing to the original bytecode.
+
+`loader` - Decompiled loader source code. Class names are all original.
+
+`tools` - Tooling specific to the client or loader.
+
+## Sources
+
+Thanks to these individuals' projects for shedding light on some things - this would've taken a lot longer to complete without their efforts.
