 # JBWAPI
+
 Pure Java [bwapi](https://github.com/bwapi/bwapi) 4.4.0 client implementation backed by [N00byEdge](https://github.com/N00byEdge)'s [JavaBWAPIBackend](https://github.com/N00byEdge/JavaBWAPIBackend) idea and automated by [Bytekeeper](https://github.com/Bytekeeper).
 
 Also contains a modified version of the pure Java BWEM implementation from [BWAPI4J](https://github.com/OpenBW/BWAPI4J).
 
-## goals
+## Goals
+
  - Have a similar (Java) interface to BWMirror to make porting BWMirror bots easy without all the DLL and JNI hassle and overhead.
- - Stay as updated as possible with the BWAPI releases
+ - Stay as updated as possible with the BWAPI releases.

+## Advantages
 
-## advantages
- - no dependency on external DLL's
- - at least [5x](https://github.com/JavaBWAPI/JBWAPI/issues/17) faster compared to bwmirror for primitives as it directly reads the memory mapped client file. Even faster for bwapi objects as it also avoids type marshalling
- - supports both 32 and 64 bit Java (e.g. [deeplearning4j](https://deeplearning4j.org/) requires 64 bit Java which bwmirror doesn't support)
- - BWEM instead of BWTA as map analyser

-## warnings
- - JBWAPI by default has Lateny Compensation disabled (and at the moment has no LatCom at all).
- - A fake BWTA is provided for easier porting, but it translates BWTA calls to their respective BWEM calls, so specific Regions/Chokepoints etc. may differ.
