+## Release
+
+We uses [cross](https://github.com/rust-embedded/cross) to generate release builds for Linux Distributions.
+For example, you could generate a static release build via the below command.
+
+```
+RUSTFLAGS="-C link-arg=-static -C target-feature=+crt-static" cross build --bin matchengine --target x86_64-unknown-linux-gnu --release
+```
+
+And a new Docker image could be generated by the `release` script.
+
+```
+# In root directory of this project
+./release/release.sh YOUR_DOCKER_REGISTRY_DOMAIN.COM:YOUR_DOMAIN_PORT NEW_IMAGE_TAG
+```
