+ArchiSteamFarm
+===================
 
-Big work-in-progress
+Big work-in-progress. This bot allows you to farm steam cards using multiple accounts simultaneously. Each account is defined by it's own XML config in `config` directory and you don´t need any steam-client running in the background.
 
-Allows you to farm steam cards using multiple accounts simultaneously.
+**Current functions:**
 
-Each account is defined by it's own XML config in "config" directory.
+ - Automatically farm steam cards using any number of active accounts
+ - Automatically accept friend requests sent from master
+ - Automatically accept all trades coming from master
+ - Automatically accept all steam cd-keys sent via chat from master
+ - SteamGuard / 2-factor-authentication support
+ - Full Mono support, tested on Debian "9.0" Stretch (testing)
 
-Current functions:
-- Does not need Steam client running, or even a GUI. Fully based on SteamKit2 and reverse-engineered Steam protocol.
-- Automatically farm steam cards using any number of active accounts
-- Automatically accept friend requests sent from master
-- Automatically accept all trades coming from master
-- Automatically accept all steam cd-keys sent via chat from master
-- SteamGuard / 2-factor-authentication support
-- Full Mono support, tested on Debian "9.0" Stretch (testing)
+**Current Commands:**
 
-TODO:
-- Smart multi-games farming till every game reaches 2 hours, then one-by-one (similar to Idle Master) - Backend code is already here, just missing the logic and tests.
-- Possible integration with SteamTradeMatcher, bot can detect dupes and trade them automatically. Again, backend code is already here, just missing actual implementation.
-- Automatic sending of steam trades to master, after game is fully farmed.
+ - `!farm` Restarts the bot and starts card-farming (again)
+ - `!exit` Stops the bot
+
+> You can use chat-commands in group-chat or private-chat with your bot.
+> The MasterID has to be set for this specific bot / config-file.
+
+**Supported / Tested Operating-Systems:**
+
+ - Windows 10 Enterprise Edition
+ - Debian 9.0 Stretch (Mono)
+ - Debian 8.1 Jessie (Mono)
+
+**TODO**:
+
+- Smart Multi-Game-Farming
+- Possible integration with SteamTradeMatcher, bot can detect dupes and trade them automatically. Backend-code is already here, just missing actual implementation.
+- Automatic sending of steamtrades to master(after game is fully farmed)
 - Probably much more
 
-This is big WIP, so feel free to send pull requests if you wish.
 
-I'll release some releases later, when everything is tested and code cleaned up.
