+# List The Stack Of Remembered Directories
+
+When you open a new Unix shell, you start in some directory, probably your
+home (`~/`) directory. As you `cd` around to different directories, there is
+a paper trail of your movements, a listing of where you've been.  You can
+view this listing of directories with the `dirs` command.
+
+```
+$ dirs
+~/
+$ cd code
+$ dirs
+~/code ~/
+$ cd /usr/bin
+$ dirs
+/usr/bin ~/code ~/
+```
+
+Each time you `cd`, the directory you have moved to is pushed onto the stack of
+visited directories. Alternatively, you can use the `popd` command to return
+to the previous directory, removing the current directory from the stack.
