+## Build
+
+```bash
+mkdir build && cd build
+# Without custom mutator (libfuzzer modify the buffer randomly)
+cmake ..
+# With custom mutator (wasm-tools mutate)
+cmake .. -DCUSTOM_MUTATOR=1
+make -j$(nproc)
+```
+
+## Manually generate wasm file in build
+
+```bash
+# wasm-tools smith generate some valid wasm file
+# The generated wasm file is in corpus_dir under build
+# N - Number of files to be generated
+./smith_wasm.sh N 
+
+# running
+``` bash
+cd build
+./wasm-mutate-fuzz CORPUS_DIR
+ 
+```
+
+## Fuzzing Server
+
+```shell
+1. Installation Dependent Environment
+$ cd server
+$ pip install -r requirements.txt
+
+2. Database Migration
+$ python3 app/manager.py db init
+$ python3 app/manager.py db migrate  
+$ python3 app/manager.py db upgrade  
+
+3. Change localhost to your machine's IP address
+$ cd ../portal 
+$ vim .env   # Change localhost to your machine's IP address  # http://<ip>:16667
+
+4. Run Server and Portal
+$ cd ..   # Switch to the original directory
+If you want to customize the front-end deployment port:  # defaut 9999
+    $ vim .env # Please change the portal_port to the port you want to use 
+
+The server is deployed on port 16667 by default, If you want to change the server deployment port:
+    $ vim .env # Please change the server_port to the port you want to use 
+    $ vim portal/.env # Please change the VITE_SERVER_URL to the port you want to use  # http://ip:<port>
+
+
+If your network needs to set up a proxy
+    $ vim .env # Change proxy to your proxy address
+
+$ docker-compose up --build -d
+Wait for completion, Access the port set by env
