-## Fork for [modded TDLib](https://github.com/c0re100/td)
+## Forked library for [modded TDLib](https://github.com/c0re100/td)
+
+When I'm refactoring my own bot from `Arman92/go-tdlib` to `zelenin/go-tdlib `
+
+I realized that zelenin's library doesn't meet my need😕
+
+So I fork it and make some changes
+
+1. Static build by default
+2. Add update [event filter](example#event-filter)
+3. Add [command](example#command) parser
+4. Receive correct message id to patch text/dice message response.
+5. Add [Pending updates](example#pending-updates)
+
+[Here](example) are a few example codes about how to use **c0re100/gotdlib**.

+## Example
+
+### Bot
+Login to bot account.
+
+### Command
+Handle user command and reply it.
+
+### Event Filter
+Since we can have many update type in updates.
+So we need to filter update events, like UpdateNewMessage, UpdateMessageSendSucceeded, UpdateMessageSendFailed, etc.
+
+### Media
+Send photo or album to chat.
+
+### Pending updates
+When starting a bot, we may have some updates that are missed to process when a listener IS NOT ready.
+
+So we need to keep specific update types in memory until a listener is set, then we can process those updates again.
+
+### Raw Update
+Get update without event filter.
