 Add a steam_settings\build_id.txt with the build id if the game doesn't show the correct build id and you want the emu to give it the correct one.
 An example can be found in steam_settings.EXAMPLE
 
+SteamHTTP:
+Add a steam_settings\http folder. The folder should contain the domain name and path to the files that will be returned by steamHTTP like so:
+For example this url: https://en.wikipedia.org/wiki/Main_Page
+Would be: steam_settings\http\en.wikipedia.org\wiki\Main_Page
+The Main_Page file would contain the data returned by the steamHTTP api when it tries to access: https://en.wikipedia.org/wiki/Main_Page
+An example that was made for payday 2 can be found in steam_settings.EXAMPLE

 Support for CPY steam_api(64).dll cracks: See the build in the experimental folder.
