-## Requirements
+## Build with local toolchain
 
 ### Install [google/protobuf](https://github.com/google/protobuf)
 
 We use `protoc` 3.5.1, to download: [protobuf/releases/tag/v3.5.1](https://github.com/google/protobuf/releases/tag/v3.5.1)
 
-## Generate the Go and Rust codes
+### Generate the Go and Rust codes
 
 ```sh
 make
 ```
 
-NOTE: Do not forget to update the dependent projects!
+## Build with docker
+
+### Build the docker image
+
+```sh
+docker build . -t tipb-builder
+```
+
+### Generate codes
+
+Basically just use the docker image instead of `make`:
+
+```sh
+# Generate All codes
+docker run -v $(pwd):/tipb tipb-builder 
+# Generate Go codes only
+docker run -v $(pwd):/tipb tipb-builder go
+# Generate Rust codes only
+docker run -v $(pwd):/tipb tipb-builder rust
+```
+
