 This is a Go library for making bots to be used on Facebook messenger. It is built on the [Messenger Platform](https://developers.facebook.com/docs/messenger-platform). One of the main goals of the project is to implement it in an idiomatic and easy to use fashion.

-You can find [examples for this library here](https://github.com/paked/messenger/blob/master/examples/).
+You can find [examples for this library here](https://github.com/retailcrm/messenger/blob/master/examples/).

 ## Tips

@ -10,27 +16,9 @@ You can find [examples for this library here](https://github.com/paked/messenger
 - You need a Facebook development app, and a Facebook page in order to build things.
 - Use [ngrok](https://ngrok.com) to tunnel your locally running bot so that Facebook can reach the webhook.

-## Breaking Changes
-
-`paked/messenger` is a pretty stable library however, changes will be made which might break backwards compatibility. For the convenience of its users, these are documented here.
-
-
- 06/2/18: Added messaging_type field for message send API request as it is required by FB
- [23/1/17](https://github.com/paked/messenger/commit/1145fe35249f8ce14d3c0a52544e4a4babdc15a4): Updating timezone type to `float64` in profile struct
- [12/9/16](https://github.com/paked/messenger/commit/47f193fc858e2d710c061e88b12dbd804a399e57): Removing unused parameter `text string` from function `(r *Response) GenericTemplate`.
- [20/5/16](https://github.com/paked/messenger/commit/1dc4bcc67dec50e2f58436ffbc7d61ca9da5b943): Leaving the `WebhookURL` field blank in `Options` will yield a URL of "/" instead of a panic.
- [4/5/16](https://github.com/paked/messenger/commit/eb0e72a5dcd3bfaffcfe88dced6d6ac5247f9da1): The URL to use for the webhook is changable in the `Options` struct.
-
-## Inspiration
-
-Messenger takes design cues from:
-
- [`net/http`](https://godoc.org/net/http)
- [`github.com/nickvanw/ircx`](https://github.com/nickvanw/ircx)
-
