+RestSharp is a lightweight HTTP API client library. It's a wrapper around `HttpClient`, not a full-fledged client on 
+its own.
 
 What RestSharp adds to `HttpClient`:
 - Default parameters of any kind, not just headers
 - Add a parameter of any kind to requests, like query, URL segment, header, cookie, or body
-- Multiple ways to add a request body, including JSON, XML, and form data
-- Built-in serialization and deserilization of JSON and XML

-**RestSharp is supported by [AWS](https://aws.amazon.com/developer/language/net/solutions/).**

+- Multiple ways to add a request body, including JSON, XML, URL-encoded form data, multipart form data with and 
+  without files
+- Built-in serialization and deserilization of JSON, XML, and CSV, as well as the ability to add custom serializers
+- Rich support for authentication
 
-## RestSharp vNext (v107+)
+## Compatibility note
 
-Finally, RestSharp has moved to `HttpClient`. We also deprecated the following:
+RestSharp 107 was a major release that brings a lot of changes. We've removed a lot of legacy code and added new 
+features. Finally, RestSharp has moved to `HttpClient`. We also deprecated the following:
 - SimpleJson in favour of `System.Text.Json.JsonSerialzer`
 - `IRestRequest`, and `IRestResponse` in favour of implementing classes
 - Everything `Http` and `IHttp` as those are just wrappers
+- Client configuration moved to `RestClientOptions` to make the client thread-safe
+- `IRestClient` interface surface substantially reduced
 
 Most of the client and some of the request options are now in `RestClientOptions`.
