-# ArchiSteamFarm
+ArchiSteamFarm
+===================
 
-Big work-in-progress
+ASF is a C# application that allows you to farm steam cards using multiple steam accounts simultaneously. Unlike idle master which works only on one account at given time, requires steam client running in background, and launches additional processes imitiating "game playing" status, ASF doesn't require any steam client running in the background, doesn't launch any additional processes and is made to handle unlimited steam accounts at once. In addition to that, it's meant to be run on servers or other desktop-less machines, and features full Mono support, which makes it possible to launch on any Mono-supported operating system, such as Windows, Linux or OS X. ASF is based on, and possible, thanks to [SteamKit2](https://github.com/SteamRE/SteamKit).
 
-Allows you to farm steam cards using multiple accounts simultaneously.
+**Core features:**
 
-Each account is defined by it's own XML config in "config" directory.
+ - Automatically farm available games 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
+ - Possibility to choose the most efficient cards farming algorithm, based on given account
+ - SteamGuard / SteamParental / 2FA support
+ - Update notifications
+ - Full Mono support, cross-OS compatibility
 
-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)
+**Setting up:**
 
-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.
-- Probably much more
+Each ASF bot is defined in it's own XML config file in `config` directory. ASF comes with included ```example.xml``` config file, on which you should base all of your bots. Simply copy ```example.xml``` to a new file, and edit properties inside. Don't forget to switch ```Enabled``` property to ```true``` once you're done, as this is the master switch which enables configured bot to launch.
 
-This is big WIP, so feel free to send pull requests if you wish.
+ASF expects exclusive access to all steam accounts it's using, which means that you should not use the account which is currently being used by ASF at the same time. You may however ```!start``` and ```!stop``` bots during farming, as well as use config property such as ```ShutdownOnFarmingFinished``` which will automatically release account after farming is done.
 
-I'll release some releases later, when everything is tested and code cleaned up.
+After you set up all your bots (their configs), you should launch ```ASF.exe```. If your accounts require additional steps to unlock, such as Steam guard code, you'll need to enter those too after ASF tries to launch given bot. If everything ended properly, you should notice in the console output, as well as on your Steam, that all of your bots automatically started cards farming.
+
+ASF doesn't require and doesn't interfere in any way with Steam client, which means that you can be logged in to Steam client as your primary account with e.g. Idle Master in the background, and launch ASF for all other accounts (your alts) at the same time.
+
+**Current Commands:**
+
+ - `!exit` Stops whole ASF
+ - `!farm` Restarts cards farming module. ASF automatically executes that if any cd-key is successfully claimed
+ - `!redeem <KEY>` Redeems cd-key on current bot instance. You can also paste cd-key directly to the chat
+ - `!start <BOT>` Starts given bot instance, after it was ```!stop```pped
+ - `!status` Prints current status of ASF
+ - `!stop` Stops current bot instance
+ - `!stop <BOT>` Stops given bot instance
+
+> Commands can be executed via a private chat with your bot.
+> Remember that bot accepts commands only from ```SteamMasterID```. That property can be configured in the config.
+
+**Supported / Tested Operating-Systems:**
+
+ - Windows 10 Professional/Enterprise Edition (Native)
+ - Windows 8.1 Professional (Native)
+ - Windows 7 Ultimate (Native)
+ - Debian 9.0 Stretch (Mono)
+ - Debian 8.1 Jessie (Mono)
+ - OS X 10.11.1 (Mono)
+ 
+However, any operating system [listed here](http://www.mono-project.com/docs/about-mono/supported-platforms/) should run ASF flawlessly.
