 This is a tool to download submissions or submission data from Reddit. It can be used to archive data or even crawl Reddit to gather research data. The BDFR is flexible and can be used in scripts if needed through an extensive command-line interface.
 
+Some quick reference commands are:
+
+  - `python3 -m bulkredditdownloader download --subreddit Python -L 10`
+  - `python3 -m bulkredditdownloader download --user me --saved --authenticate -L 25 --file-scheme '{POSTID}'`
+  - `python3 -m bulkredditdownloader download --subreddit 'Python, all, mindustry' -L 10 --make-hard-links`
+  - `python3 -m bulkredditdownloader archive --subreddit all --format yaml -L 500 --folder-scheme ''`
+
 ## Usage
 
 The BDFR works by taking submissions from a variety of "sources" from Reddit and then parsing them to download. These sources might be a subreddit, multireddit, a user list, or individual links. These sources are combined and downloaded to disk, according to a naming and organisational scheme defined by the user.
