+# TelegramBotAPI Behaviour Builder Extensions
+
+This extension was created to make it more simple to build bot steps handling. Usually, you must use something like:
+
+```kotlin
+val bot = telegramBot(TOKEN)
+bot.startGettingFlowsUpdatesByLongPolling {
+    messagesFlow.subscribeSafelyWithoutExceptions {
+        // ...
+    }
+    // here I already tired to write this example 😫
+}
+```
+
+This library offer other way to do a lot of routine in more simple way:
+
+```kotlin
+telegramBot(token) {
+    onCommand("start".regex) {
+        execute(SendTextMessage(it.chat.id, "This bot can ...")) // replaceable with reply(it, "This bot can ...") when you are using `tgbotapi.extensions.api`
+    }
+}
+```
+
+## Triggers
+
+In terminology of this project the `Triggers` are things which have no initial message, may have own filter for incoming
+messages and filter messages for context which will be used in subcontext. Full syntax with `onText` as an example:
+
+```kotlin
+telegramBot(TOKEN) {
+    onText(
+        includeFilterByChatInBehaviourSubContext = true, // if false - last lambda will receive all messages instead of filtered by chat messages
+        additionalFilter = { message: CommonMessage<TextContent> ->
+            // here you may check incoming message for any requirements before it will be passed to the main lambda
+        }
+    ) { message: CommonMessage<TextContent> -> // this here is `BehaviourContext`
+        // here put your actions and additional waiters
+    }
+}
+```
+
+## Waiters
+
+Waiters targeted to get some content "here and now", they must be used inside some trigger main lambda:
+
+```kotlin
+telegramBot(TOKEN) {
+    onCommand("start") { message: CommonMessage<TextContent> ->
+        val userPhotos = waitPhoto(
+            SendTextMessage(it.chat.id, "Ok, send me some photo, please"), // init request, can be any `Request` object
+            { update: Update -> // That is update which is NOT passed requirements. In current context we expect some photo, but received something else
+                SendTextMessage(it.chat.id, "Excuse me, but I can accept only photos") // it could be null
+            },
+            2, // some count of photos
+            includeMediaGroups = true, // if false, messages related to some media group will be skipped and recognized as incorrect
+        ) { message: CommonMessate<PhotoContent> -> // this method is optional and you can use it in case you want to add some additional requirements checks
+            message.content // return null if message didn't passed requirements
+        }
+    }
+}
