 ## Progress
 
-Our first milestone is 2020/09/20, when the first ACL contest is planned.
-We aim to implement the same toolset as original ACL(C++) on the day.
+We are trying to keep up with the original ACL, to make APIs user-friendly, to fix known bugs, and so on.
 
-We are trying to implement with the same files by referring to the original ACL's hpp.
-After that we try to improve our development flow, tests, or utilities.
