+#### How to develop
+
+1. Install [Go environment](https://golang.org/doc/install). Make sure Go version is at least 1.15.
+
+2. Install `Nodejs` and `pm2`
+
+```
+    curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
+    npm install pm2 -g
+```
+
+2. Clone the Open-IM project to your server.
+
+   ```
+   git clone https://github.com/OpenIMSDK/Open-IM-Server.git --recursive
+   ```
+
+3. Start Service.
+
+    ```
+    # run etcd/mongodb/mysql/redis/kafka
+    docker-compose -f docker-compose.local.yaml up -d
+
+    # run open-im services
+    pm2 start app.yaml --watch
+    pm2 ls
+    pm2 logs
+    ```
+
+or try with `docker-compose`
+
+```
+    docker-compose -f docker-compose.dev.yaml up -d
+    docker-compose -f docker-compose.dev.yaml ps
+    docker-compose -f docker-compose.dev.yaml logs -f
+```

 ### CONFIGURATION INSTRUCTIONS
 
 > Open-IM configuration is divided into basic component configuration and business internal service configuration. Developers need to fill in the address of each component as the address of their server component when using the product, and ensure that the internal service port of the business is not occupied
