 ## Usage
 
-First of all, you need to create named pipe (FIFO). It can be done by running following command:
+First, you need to check your XDG_RUNTIME_DIR variable
 ```
-mkfifo ~/.cache/.pipeplayer
+echo $XDG_RUNTIME_DIR
+```
+
+If you see no output, then you need to export variable:
+
+On bash, zsh etc.:
+```
+export XDG_RUNTIME_DIR="$HOME/.local/runtime"
+```
+On fish:
+```
+set -x XDG_RUNTIME_DIR "$HOME/.local/runtime"
+```
+
+Then make sure directory $XDG_RUNTIME_DIR exists:
+```
+mkdir -p "$XDG_RUNTIME_DIR"
 ```
 
 Then, you can start daemon either during start of your desktop environment or window manager or even in tty with this command:
