 mkxp primarily targets technically versed users that are comfortable with Ruby / RGSS, and ideally know how to compile the project themselves. The reason for this is that for most games, due to Win32-API usage, mkxp is simply not a plug-and-play solution, but a building block with which a fully cross-platform version can be created in time.
 
 ## Bindings
-Bindings provide the glue code for an interpreted language environment to run game scripts in. Although mkxp-z still contains all pre-existing bindings at the moment, mkxp-z focuses on Ruby 1.8 and as such it isn't unlikely that the other bindings may even be removed completely. Please see the original README for more details.
