+This is a build of the experimental version of my emu in steamclient mode with an included loader. See both the regular and experimental readmes for how to configure it.
+Note that all emu config files should be put beside the steamclient dll. You do not need to put a steam_interfaces.txt file for the steamclient version of the emu.
+
+To use the loader, put both steamclient dlls and the loader in a folder and edit the config file. Make sure you put the right appid in the ini file.

 Offline mode:
 Some games that connect to online servers might only work if the steam emu behaves like steam is in offline mode. If you need this create a offline.txt file in the steam_settings folder.
 
+Disable networking:
+If for some reason you want to disable all the networking functionality of the emu you can create a disable_networking.txt file in the steam_settings folder. This will of course break all the
+networking functionality so games that use networking related functionality like lobbies or those that launch a server in the background will not work.
+
 Custom Broadcast ips:
 If you want to set custom ips (or domains) which the emulator will send broadcast packets to, make a list of them, one on each line in: Goldberg SteamEmu Saves\settings\custom_broadcasts.txt
 If the custom ips/domains are specific for one game only you can put the custom_broadcasts.txt in the steam_settings\ folder.
 An example is provided in steam_settings.EXAMPLE\custom_broadcasts.EXAMPLE.txt
 
-Items or Inventory:
-Create a folder named steam_settings right beside steam_api.dll if there isn't one already. In that folder, create a file named items.json which will contain every item you want to have in your game.
+Achievements, Items or Inventory:
+Create a folder named steam_settings right beside steam_api.dll if there isn't one already. In that folder, create a file named items.json and/or achievements.json which will contain every item/achievement you want to have in your game.
 An example can be found in steam_settings.EXAMPLE that works with Killing Floor 2.
 The items.json syntax is simple, you SHOULD validate your .json file before trying to run your game or you won't have any item in your inventory. Just look for "online json validator" on your web brower to valide your file.
 You can use https://steamdb.info/ to list items and attributes they have and put them into your .json.
