 Start server on localhost using the commands below.
 ```bash
 chmod +x simple-dict-server simple-dict-client
-./simple-dict-server -d 7777 1 ./dict.bin    # use -d to start as daemon
+./simple-dict-server -d 7777 1 ./dict.sp ./cfg.sp    # use -d to start as daemon
 ```
 Open another shell to connect to it.
 ```bash
 ./simple-dict-client 127.0.0.1 7777
 ```
 Now you have connected to the server. Type `fumiama` and press enter in `10` seconds to get the read/write access. You can modify the password in source code as you like. Please note that the server will only wait `10` seconds for a response after the last communication. The box below shows how to control the server to accompilsh basic add/del/find/edit operations.
