 - (optional) Add configuration to your `~/.vimrc` file to bind JSLint to a key.
   For example:
 
         " Run JSLint on the current file when <F5> is pressed.

+To get a detailed report of any issues in your JavaScript file outside of Vim,
+run the `bin/jslint` executable in a terminal. For example:
 
       $ bin/jslint plugin/jslint/fulljslint.js

 requires that the Vim plugin is installed and also requires Ruby.
 
 
+Working with quickfix
+-----------------------
+
+The quickfix window will display a list of all potential errors in the file
+with an explanation for each. Running `:JSLint` will automatically open the
+quickfix window if there are potential errors and will close it if no problems
+are detected.
+
+Note that the quickfix list will be cleared and regenerated every time you run
+`:JSLint`.
+
+Here are some quick notes for using quickfix:
+
+- In the quickfix window, moving your cursor over an item and pressing enter
+  will jump the cursor to that line in your file.
+
+- In either your file or the quickfix window `:cn` will jump the cursor to the
+  next potential error, and `:cp` will jump the cursor to the previous item.
+
+- Open and close the quickfix window with `:copen[n]` and `:cl[ose]`.
+
+You can find more detailed documentation in the [Vim Reference Manual][quickfix
+manual].
