+#### DevContainer
+
+To support developers join the project without deploying the build env, we
+provide VSCode `DevContainer`.
+
+-   Install VSCode and Docker;
+-   Install the plugin `ms-vscode-remote.remote-containers` under VSCode;
+-   Open `Carban` project folder in
+    [VSCode](https://docs.microsoft.com/en-us/azure-sphere/app-development/container-build-vscode#build-and-debug-the-project);
+    <br> Visual Studio Code detects the new files and opens a message box
+    saying:
+    `Folder contains a Dev Container configuration file. Reopen to folder to develop in a container.`
+-   Select the `Reopen in Container` button to reopen the folder in the
+    container created by the `.devcontainer/Dockerfile` file;
+-   And then, you are ready to start writing code.
