 ## Quick Start
 
-### Local Disk
+### Prerequisites
+
+Please ensure the src directory and target directory exists first, replace the following path with your real path.
+
+```bash
+$ mkdir src target
+```
+
+Generate the TLS cert file and key file for testing purposes.
+
+The TLS cert and key files are just used by [File Server](#file-server) and [Remote Disk Server](#remote-disk-server).
+
+```bash
+$ go run $GOROOT/src/crypto/tls/generate_cert.go --host 127.0.0.1

-For example, monitor src directory and sync change files to target directory.

 ### SyncOnce
 
 Sync the whole path immediately from src directory to target directory.
 
 ```bash
-gofs -src=./src -target=./target -sync_once
+$ gofs -src=./src -target=./target -sync_once

 ### Daemon Mode
 
 Start a daemon to create subprocess to work, and record pid info to pid file.
 
 ```bash
-gofs -src=./src -target=./target -daemon -daemon_pid
+$  gofs -src=./src -target=./target -daemon -daemon_pid
