 ### Authentication
 - It is recommended to use `ABLY_KEY` at server side. Check [official ably auth documentation](https://ably.com/docs/auth) for more info.
-- `ABLY_KEY` should not be exposed at client side where it can be used for unintentional purposes.
+- `ABLY_KEY` should not be exposed at client side where it can be used for malicious purposes.
 - Server can use `ABLY_KEY` for initializing the `AblyRest` instance.
 
 ```csharp
 var rest = new AblyRest("API_KEY");
 ```
 - Token requests are issued by your servers and signed using your private API key. 
 - This is the preferred method of authentication as no secrets are ever shared, and the token request can be issued to trusted clients without communicating with Ably.
-e.g. ASP.Net server app
 ```csharp
+// e.g. ASP.Net server endpoint
