+### Use Dev Container
+
+If you have installed docker and VS Code on your machine, please add extension **Dev Containers** to VS Code, then you can use it to quickly setup your local development environment.
+
+1. Add **.env** file under folder **.devcontainer** , you can put environment variables in it, these env vars will appear in the docker container. And **.env** has been put in the .gitignore, so you can put secrets in it, it will not be merge to github repo. Content of it:
+
+```
+ARTIFACTORY_URL=[artifactory url]
+ARTIFACTORY_REPO=[repo contains software installer]
+ARTIFACTORY_TOKEN=[token of artifactory]
+LOCAL_PATH=/workspaces/spm-middleware
+```
+2. After the dev container startup, you need to:
+    
+    a. install python packages
+    ```
+    pip install -r requirements.txt
+    ```
+
+    b. copy ansible plugins for molecule test
+    ```
+    mkdir -p /home/vscode/.ansible/plugins/
+    cp -r plugins/* /home/vscode/.ansible/plugins/
+    ```
+
+3. Then you can test if molecule works correctly:
+
+    ```
+    molecule test -s websphere-v90-rockylinux8
+    ```
