+Since 1.2.0 ASL requires a [supportInfo](https://community.bistudio.com/wiki/supportInfo) file, which must be generated, named "types" and placed right next to the binary. The content looks like:
+
+```
+...
+t:DIARY_RECORD

+b:OBJECT,GROUP enableattack BOOL

+#ASL Tools
+A visual tool set to ease the work of asl developers.
+Maintained by yours truly: [654wak654](https://github.com/654wak654/)
+
+**Notepad++ Syntax Higligthing**: https://github.com/DeKugelschieber/asl/blob/master/tools/asl.xml
+
+Feel free to contribute with another text editor's syntax higligthing plugin.
+
+##ASL GUI <img src="https://img.shields.io/badge/version-1.1.0.0-orange.svg" alt="version">
+An optional Java interface to make the compile procces of ASL faster and more user-friendly. It's released under the MIT licence just like the core project. It also helps with error reporting of asl.
+
+**Version 1.1.0.0**
+- New Arma 3-themed look, and error reporting straight from asl.
+- Program now depends on asl.exe, they need to be in the same directory.
+
+**Version 1.0.0.0**
+- More style changes and bug fixes, marked ready for release.
+
+**Version 0.3.0.0:**
+- Fixed some possible bugs, did some style fixes and other code adjustments. It's now is readable without getting cataracts. Mostly anyway...
