 ## Usage
 
-The main point of entry is the `Bitbucket\Client` class. Simply create a new instance of that, authenticate, and you're good to go! As of time of writing (Tuesday 29th June 2020), every endpoint (excluding issue export and import, and various deprecated endpoints) available on the Bitbucket API 2.0 is also available through this PHP client. We'd recommend looking through the [Bitbucket documentation](https://developer.atlassian.com/cloud/bitbucket/rest/intro/), and also the [source code](https://github.com/BitbucketPHP/Client/tree/5.1/src) to get a full picture of what is available to use.

+It is possible to authenticate using HTTP Basic credentials. For [Bitbucket API tokens](https://support.atlassian.com/bitbucket-cloud/docs/api-tokens/), use your Atlassian account email as the username and the API token as the password:
 
 ```php
 $client = new Bitbucket\Client();
 
 $client->authenticate(
     Bitbucket\Client::AUTH_HTTP_PASSWORD,
-    'your-username-here',
-    'your-password-here'

 #### JSON Web Token
 
-Finally, we support logging in using JSON web tokens (JWTs). This method is exclusively required by some of Bitbucket's API endpoints, such as the addons API. Generate your JWT, perahps using [lcobucci/jwt](https://github.com/lcobucci/jwt/tree/4.3.0), then provide it as below:
