 # Minecraft bot stress tester
 🤖 A simple open source app written in Java used for stress testing Minecraft servers with bots (fake players).  
 💥 It can be also used to test plugins or minigames.  
-✔️ The MC version of the bots is 1.19.1 (and 1.19.2)
+✔️ The MC version of the bots is 1.20 (supports 1.20.x).  
+For older MC versions please look in the [releases](https://github.com/crpmax/mc-bots/releases " releases").
 
 ## 🆒 Features
 - ✅ Connect as many bots as you want
 - ✅ Use SOCKS4 or SOCKS5 proxies from file or URL
 - ✅ Receive colored or noncolored chat
 - ✅ Set connection delay
-- ✅ Set message or command on join
+- ✅ Set messages or commands on join
 - ✅ Generate random or real looking nicknames or load from file
+- ✅ Online (premium) account support with login using Microsoft OAuth - only for migrated accounts  
+- ✅ Control all or selected bots
 
 ## 📖 Usage
 Minimal Java version: 8

 When running, you can write a chat message to the terminal to send it by all bots.
 
 ## 🧪 Example
-`java -jar mc-bots-1.2.4.jar -s 192.168.0.189:25565 -p BOT_ -d 4000 5000 -c 30 -r`  
+`java -jar mc-bots-1.2.6.jar -s 192.168.0.189:25565 -p BOT_ -d 4000 5000 -c 30 -r`  
 This will connect 30 bots to server at 192.168.0.189:25565 with delay 4000-5000 ms and will use real-looking nicknames prefixed with BOT_

 ## ⚡ Options
 `-c <count>` The count of bots to connect, default is 1  
 `-d <min> <max>` Set the minimum and maximum connection delay range in ms, default is 4000-5000  
-`-j <message>` The message or command to send on join, does not work with `-m` or `-x` option  
+`-j <message>` Messages or commands to send on join, separated by `&&`, does not work with `-m` or `-x` option  
 `-p <prefix>` Custom bot nickname prefix eg. `BOT_`  
 `-r` Generate real looking nicknames instead of random ones  
 `-n` Do not use color in terminal - useful when the terminal does not support it  
 `-m` Minimal run - do not use any listeners, will not receive chat, useful for large amounts of bots  
 `-x` The most minimal run - No listeners, no control, no chat - useful for large amounts of bots for better performance  
-`-t` Set proxy type - SOCKS4 or SOCKS5  
+`-t <type>` Set proxy type - SOCKS4 or SOCKS5  
-`-l` Set proxy list file  
+`-l <path>` Set proxy list file  
 `-g` Try to simulate gravity by falling down  
-`--nicks` Set nicknames file  
+`-o` Use online (premium) account (login with Microsoft OAuth)  
+`-ar <delay>` Set auto-respawn delay (default is 100 ms, set to -1 to disable)  
+`--nicks <file>` Set nicknames file  
+
+
+## Commands
+Commands can be typed to the console. They are prefixed with `.` or `!`.
+Without the prefix it will be sent as a chat message!  
+`.list` or `.ls` - list all connected bots  
+`.control <nick>` or `.ctrl <nick>` - select one or multiple bots to control  
+`.exit <limit>` or `.leave <limit>` - disconnect all or specified number of bots
