+=== Configuring a dynamic prompt ===
+To have a prompt that shows your pwd and user name, add the following lines to your lib/profile. Place them in the 'case cpu' section replacing the cpu% prompt line
+<code>
+prompt=('['^`{pwd}^'] '^$sysname^'% ' ' ')
+fn cd {builtin cd $* && prompt=('['^`{pwd}^'] '^$sysname^'% ' ' ')}
+</code>
+These lines update the prompt, and replace the 'cd' command so that the prompt is updated each time you change a directory.
