 as the focused applications. This is especially useful if you want to open
 a new terminal for debugging or compiling purpose.
 
+Disclaimer
+----------
+This script *can't* retrieve the working directory of a "single instance
+application" nor terminal multiplexer, e.g. :
+  - tmux, screen
+  - lilyterm
+  - konsole
+  - urxvt*c*
+  - applications with tabs
+
+The application works well with the following terminals :
+  - urxvt
+  - xterm
+  - gnome terminal
+
 How it works
 ------------
-Since there is no proper options to get the pid of the currently focused
-windows, xcwd first try to read the `_NET_WM_PID` property.
-If it fails, it reads the `_NET_WM_CLASS` and compares it to the name of
-all the running processes (it's kind of `pidof name`).
-
-When xcwd has got the PID, it search the deepest child he has, thus avoiding
-getting the working directory of the terminal emulator instead of the shell.
-
-Finally it prints the content of `/proc/pid/cwd` on the standard output.  If
-xcwd was unable to find the PID, it prints the content of the `HOME` variable.
+  - Retrieve the focused window
+  - Read its attributes to get the PID. If `_NET_WM_PID` is set, xcwd just
+    read the value. Otherwise it reads the `_NET_WM_CLASS` and compares it to
+    the name of all the running processes
+  - Search for the deepest child of the selected PID (to avoid getting the
+    working directory of the terminal instead of the shell)
+  - Print the current working directory
 
-Disclaimer
-----------
-This script can't retrieve the working directory of a shell in tmux, screen
-or in an instance of urxvtc.
+If one of those steps fail, xcwd print the content of the `HOME` variable.
