+# Telegram Bot API in Kotlin
+
+Idiomatic, fluent and type-safe Kotlin bindings for [Telegram Bot API](https://core.telegram.org/bots/api).
+
+```kotlin
+val poller = TelegramBotApiPoller(TelegramBotApiClient(botApiToken))
+poller.start(TelegramBotUpdateListener(
+    onMessage = { message ->
+        message.reply(
+            text = "Hello, *${message.from?.firstName ?: "stranger"}*!",
+            parseMode = ParseMode.MARKDOWN,
+            replyMarkup = inlineKeyboard {
+                buttonLink("Telegram", "https://telegram.org")
+                row {
+                    button("Bot", "bot")
+                    button("API", "api")
+                }
+            }
+        )
+    },
+    onCallbackQuery = { callbackQuery ->
+        when (callbackQuery.data) {
+            "bot" -> callbackQuery.answer("🤖")
+            "api" -> callbackQuery.answer("🚀")
+            else -> callbackQuery.answer("🤷")
+        }
+    }
+))
+```
+
+## Compatibility
+
+The bindings are generated directly from the source-of-truth [Bot API spec](https://core.telegram.org/bots/api).
+
+| Telegram Bot API | tbot-api library |
+|------------------|------------------|
+| 6.9              | 0.4.0            |
+
+
+## Developing
+
+### Updating API to a new version of Telegram Bot API
+
+```
+./gradlew :buildSrc:updateApiSpec --no-configuration-cache
+./gradlew generateTelegramBotApi
+./gradlew apiDump
+./gradlew check
+```
+
+## Roadmap
+
+### Alpha
+
+- [ ] Error handling
+
+### Beta
+
+- [ ] Cleaner package structure
+- [ ] Strict library member visibility
+- [ ] Forward compatibility: published versions of the library should not break with new API versions (union types and enums)
+- [ ] Support for integration tests bots
