+# Compile
+You should first clone this project into a system with cmake & libpthread installed.
+If you plan to compile it on Windows, you should edit the source code to transform the socket/thread/file libraries into Windows version.
+```bash
+git clone https://github.com/fumiama/simple-dict-server.git
+```
+Now we will create a `build` folder.
+```bash
+cd simple-dict-server
+mkdir build
+```
+Then use `cmake` command to generate files for `make` automatically.
+```bash
+cd build
+cmake ../
+```
+Now you can use `make` to generate executable binary files named `simple-dict-server` and `simple-dict-client` in `./build` directory.
+```bash
+make
+```
+
+# Use
+Now we will show you how to start the server on localhost. You can try the command below.
+```bash
+chmod +x simple-dict-server simple-dict-client
+./simple-dict-server -d 7777 1 ./dict.bin    # use -d to start as daemon
+Bind server success!
+Listening....
+Ready for accept, waitting...
+Run on thread No.0
+
+```
+Then you can 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 the source code as you like. Please note that the server will only wait `10` seconds for a response after the last communication. The communication below shows how to control the server to accompilsh basic add/del/find/edit operations.
+```bash
+break!
+Get sockfd
+Connected to server
+Welcome to simple dict server.
+Thread create succeeded
+Enter command:fumiama
+Enter command:set     #set a key-value pair
+Recv 3 bytes: set
+Enter command:test    #key
+Recv 4 bytes: data
+Enter command:测试    #value
+Recv 4 bytes: succ
+Enter command:get     #get a value using key
+Recv 3 bytes: get
+Enter command:test

+Enter command:lst   #list all keys match pattern
+Recv 3 bytes: lst
+Enter command:t     #pattern
+Recv 5 bytes: test
+
+Enter command:quit
+Enter command:^C
+```
+You can also use `cat` command to get the raw data directly.
+```bash
+break!
+Get sockfd
+Connected to server
+Welcome to simple dict server.
+Thread create succeeded
+Enter command:fumiama
+Enter command:cat
+Recv 131 bytes: 128test测试
+Enter command:quit
+Enter command:^C
+```
+The raw data starts with a integer showing the size of data, then send all data in `./dict.bin` to the client.
