+api = API('https://my.endpooint.base/api/v1/', authKeyHeader='my_token_header' authSecret='my_token')

 All of this parameters have as default `None` so if you don`t provide them you have a no authenticated connection.

-api = API(`https://my.endpooint.base/api/v1/`)
+api = API('https://my.endpooint.base/api/v1/')
 ```
 
 #### SSL
 drowse expose the requests verify flags, which controls if to verify or not the SSL certificate of the endpoint. It defaults to `True` but if you want to test a REST api with self-signed certificates
 you can set it to False.
 
 ```python
-api = API(`https://my.endpooint.base/api/v1/`, verify=False)
+api = API('https://my.endpooint.base/api/v1/', verify=False)
 ```
