+## Reading profiles
+
+To get a user's profile:
+
+```ruby
+profile = client.get_profile("7770386109746442")
+```
+
+`Threads::API::Client#get_profile` accepts a `fields` option, which is an Array (or comma-separated String) of fields to include in the response. By default, all documented fields are requested. See the [Threads API documentation](https://developers.facebook.com/docs/threads/threads-profiles#fields) for a list of available fields.

 ## Posting to Threads
 
 Posting to Threads is, at the very least, a two-step process. Threads requires that you first create a container for the media you want to post, then explicitly publishing that container as a thread. However, more steps are involved if you want to post multiple media items in a single thread.
