 The Linux Knowledge-Base provides quick-start guides for working with terminal programs.
 
+If you like this style of short articles with a miniature database, then join me in my quest to remove the nausea of poorly-written documentation.

 # Setup
 
 Install `make`, `recutils`, and any fuzzy-finder (i.e. `sk`, `fzy`, or `fzf`).
 
 ## Usage
 
+Set up the database and try a few queries:
 
 ```sh
 make
 make database
 
+recsel db.rec -m 3
 recsel db.rec -q database
-recsel db.rec -q gpg
 recsel db.rec -e "title = 'ssh'"

+## State Knowledge Dependencies
+
+Articles should state what you need to understand in order to read them *at the start*.
+They should not assume the reader knows much beyond common terminal commands, and should not provide a link to some other resource half-way through an article.
+
+People should be able to read an article from the beginning, then keep going until the end, and then stop.
+Articles should not take a detour through a chain of other articles of unknown size.

 ## Be Opinionated
 
 - Guides should not ask the reader to select options half-way through.

+## Assume People Follow the Instructions
+
+Articles should say what to type, not the output.
+If the command is `ls`, users will see files once they try the command, but the article does not need to provide an example list of files unless an important point has to be made about output.
