 ## Installation
 
-Threee methods:
+Two methods:
 1. [Docker](https://tikazyq.github.io/crawlab/Installation/Docker.md) (Recommended)
-2. [Direct Deploy](https://tikazyq.github.io/crawlab/Installation/Direct.md)
-3. [Preview](https://tikazyq.github.io/crawlab/Installation/Direct.md) (Quick start)
+2. [Direct Deploy](https://tikazyq.github.io/crawlab/Installation/Direct.md) (Check Internal Kernel)

+### Pre-requisite (Docker)
+- Docker 18.03+
+- Redis
+- MongoDB 3.6+
+
+### Pre-requisite (Direct Deploy)
+- Go 1.12+
+- Node 8.12+
+- Redis
+- MongoDB 3.6+
+
+## Run
+
+### Docker
+
+Run Master Node for example. `192.168.99.1` is the host machine IP address in Docker Machine network. `192.168.99.100` is the Master Node's IP address. 
+
+```bash
+docker run -d --rm --name crawlab \
+        -e CRAWLAB_REDIS_ADDRESS=192.168.99.1:6379 \
+        -e CRAWLAB_MONGO_HOST=192.168.99.1 \
+        -e CRAWLAB_SERVER_MASTER=Y \
+        -e CRAWLAB_API_ADDRESS=192.168.99.100:8000 \
+        -e CRAWLAB_SPIDER_PATH=/app/spiders \
+        -p 8080:8080 \
+        -p 8000:8000 \
+        -v /var/logs/crawlab:/var/logs/crawlab \
+        tikazyq/crawlab:0.3.0
+```
+
+Surely you can use `docker-compose` to one-click to start up. By doing so, you don't even have to configure MongoDB and Redis databases.
+
+```bash
+docker-compose up
+```
+
+For Docker Deployment details, please refer to [relevant documentation](https://tikazyq.github.io/crawlab/Installation/Docker.md).
