 `node app.js --user={username}`
 
 ### Optional parameters
-* `--limit={number}`: Maximum amount posts to fetch content from
+* `--users={user1,user2}`: You may fetch posts from multiple users by either supplying a comma-separated list of usernames (no spaces) with `--users`, or using multiple individual `--user` arguments
+* `--limit={number}`: Maximum amount posts per user to fetch content from
 * `--sort={method}`: How posts should be sorted while fetched. This affects the `$postIndex` variable, and in combination with a `--limit` decides what posts will be included
 
+### Examples
+* `node app.js --user=ThePendulum`
+* `node app.js --user=ThePendulum --limit=10 --sort=top`
+
 ## Configuration
 The default configuration aims to be sensible, and the application may be used without any further tweaking. However, a multitude of options make this utility particularly powerful.
