+# PlaguBot
+
+[PlaguBot](https://github.com/InsanusMokrassar/PlaguBot) is a small framework for unifying developing of modules of bots. It is built with two parts:
+
+* [Plugin](https://github.com/InsanusMokrassar/PlaguBot/blob/master/plugin/src/main/kotlin/dev/inmo/plagubot/Plugin.kt)
+* [Bot](https://github.com/InsanusMokrassar/PlaguBot/tree/master/bot/src/main/kotlin/dev/inmo/plagubot)
+
+## Plugin
+
+Plugin is a partially independent part of bot. Plugin have several parts:
+
+* `setupDI` - this method should be used to configure DI part of module
+* `setupBotPlugin` - method to start/configure your bot actions
+
+Plugin realization should be an `object` or `class` with empty constructor.
+
+## Bot
+
+Most important of bot is `main` function (full reference: `dev.inmo.plagubot.AppKt`). It consumes one argument - path to config.
+
+Bot is initializing with the next algorithm:
+
+```mermaid
+flowchart TB
+    main["Main"]
+
+    subgraph ConfigReading
+        ConfigJsonParsing["Parsing to Json"]
+        ConfigParsing["Parsing to global config"]
+        ConfigJsonParsing --> ConfigParsing
+    end
+    ConfigReading["Reading of config"]
+    
+    BotConstructorCalling["Calling of PlaguBot constructor"]
+
+    subgraph BotStart
+        BotStartKoinAppInit["Initialization of koin app"]
+        
+        subgraph BotStartSetupDI
+            sample
+        end
+        
+        BotStartKoinAppInit --> BotStartSetupDI
+    end
+    
+    main --> ConfigReading
+    ConfigReading --> BotConstructorCalling
+    BotConstructorCalling --> BotStart
+```
