 - `quit --output-selected-files`: if `--output-file` argument is set, output the selected files to it
   - exit code 102
 
-The following is a bash snippet on how to integrate with `quit`
-
-```bash
-function joshuto() {
-	ID="$$"
-	mkdir -p /tmp/$USER
-	OUTPUT_FILE="/tmp/$USER/joshuto-cwd-$ID"
-	env joshuto --output-file "$OUTPUT_FILE" $@
-	exit_code=$?
-
-	case "$exit_code" in
-		# regular exit
-		0)
-			;;
-		# output contains current directory
-		101)
-			JOSHUTO_CWD=$(cat "$OUTPUT_FILE")
-			cd "$JOSHUTO_CWD"
-			;;
-		# output selected files
-		102)
-			;;
-		*)
-			echo "Exit code: $exit_code"
-			;;
-	esac
+To exit into the current directory you need to add a snippet to your preferred shell's init script to integrate with `quit`.
