+[![Maven Central](https://maven-badges.herokuapp.com/maven-central/dev.inmo/plagubot.plugins.commands/badge.svg)](https://maven-badges.herokuapp.com/maven-central/dev.inmo/plagubot.plugins.commands)
+
+This plugin has been created for centralized work with commands in your plugins.
+
+## How to use
+
+End user should include in his plugins section next line:
+
+```json
+...
+"plugins": [
+  ...,
+  "dev.inmo.plagubot.plugins.commands.CommandsPlugin"
+],
+...
+```
+
+Then, in your plugin you should register your commands. Just pass them inside `setupDI` as `BotCommandFullInfo`:
+
+```kotlin
+// ... Your plugin code
+    override fun Module.setupDI(database: Database, params: JsonObject) {
+        // ...
+        single { BotCommand("commandExample", "Command description").full() }
+        // ...
+    }
+// ...
+```
+
+You may pass info `full` extension:
+
+* Any [BotCommandScope](https://tgbotapi.inmo.dev/docs/dev.inmo.tgbotapi.types.commands/-bot-command-scope/index.html)
+* Some language code as `String` OR:
+* Any [IetfLanguageCode](https://microutils.inmo.dev/micro_utils.dokka/dev.inmo.micro_utils.language_codes/%5Bcommon%5D-ietf-language-code/index.html)
+
+### Runtime commands changing
+
+In runtime you may change the commands of bot using `CommandsKeeper`. The instance of `CommandsKeeper` can be
+retrieved from `koin` via simple `koin.get<CommandsKeeper>()` or `koin.commandsKeeper`:
+
+```kotlin
+// ...
+    override suspend fun BehaviourContext.setupBotPlugin(koin: Koin) {
+        val commandsKeeper = koin.commandsKeeper
+        // ... Some your code
+        commandsKeeper.addCommand(BotCommand("commandExample", "Command description"))
+        // ... Some your code
+    }
+// ...
+```
+
+Just as in the code above (in `setupDI`) you may pass all the command environment and it will be automatically updated
+for bot.
+
+## How to include
+
+Add dependency:
+
+Gradle:
+
+```groovy
+api "dev.inmo:plagubot.plugins.commands:$commands_version"
+```
+
+Maven:
+
+```xml
+<dependency>
+    <groupId>dev.inmo</groupId>
+    <artifactId>plagubot.plugins.commands</artifactId>
+    <version>${$commands_version}</version>
+</dependency>
+```
