+## Configuration (Optional)
+
+* Create `SteamAPICheckBypass.ini` and write file names you want to replace. Example:
+
+```text
+[Replace]
+OriginalFileFile=ReplaceFileName
+steam_api64.dll=steam_api64.dll.bak
+steam_api.dll=steam_api.dll.bak
+
+[AfterFirstTime]
+OriginalFileFile=0
+steam_api.dll=0
+```
+
+* `Replace`: The file name to replace.
+* `AfterFirstTime`: Start to replace after the first read of the file.
+
+## Internal Process
+
+1. The Crack will check `useinternallist` in the source code, if it's true, it will use `internalreplaceList`.
+
+2. The Crack will try to parse the ini file and add them into the replace list.
+
+3. If ini file not exist, try find `steam_api(64).dll.bak`, `steam_api(64).org`,`steam_api(64)_o.dll` and add the existed file into replace list.
