+### Run in Docker
+
+Install [Docker](https://docs.docker.com/get-docker/) first, then run the following command to start a single node development chain. This command will firstly comipile your code, then start a local dev netork.
+
+```bash
+./scripts/docker_run.sh
+```
+
+If you just want to run the compiled binary,
+
+```bash
+./scripts/docker_run.sh ./target/release/node-template --dev --ws-external
+```
+
+Other commands are similar. Let's try purge the local dev chain here:
+
+```bash
+./scripts/docker_run.sh ./target/release/node-template purge-chain --dev
+```
+
+You can also check whether the code is able to compile or not,
+
+```bash
+./scripts/docker_run.sh cargo check
+```
