 # Mario Kart 64
 
-This repo contains a work-in-progress decompilation of Mario Kart 64 (U).

 ## Progress
 
-The Mario Kart 64 code-base contains thirty-six C files, around twenty-eight files remain for decompilation. This does not account for other kinds of files such as data. The source is in an experimental 'shiftable' state that may allow modding but glitches and crashes are prevalent and the code-base will alter significantly overtime. As such, feedback that raises awareness of new issues are welcome. Please review issue #1 prior to issue submission to avoid duplicates.
+The Mario Kart 64 code-base contains thirty-five C files, around twenty-seven files remain for decompilation. This does not account for other kinds of files such as data. The source is in a 'shiftable' state that may allow modding but glitches may exist. Keep in-mind the code-base will alter significantly overtime.
