+# Changelog for MishkaInstaller 0.1.0
+
+> Kindly ensure that the MishkaInstaller Library is updated as quickly as feasible. This version includes rewriting whole project. It should be noted we do not support previous versions.
+
+You will see that this version of the project has undergone a total overhaul, and the strategy that was taken to it has been radically altered.
+
+Because of this, it is not possible to write down the details, and each area has its own document that you are able to study thoroughly.
