 ### The way to build the image:
+
+For multiple platforms:
+```
+cp target/aarch64-unknown-linux-musl/release/akasa docker-files/bins/arm64
+cp target/x86_64-unknown-linux-musl/release/akasa docker-files/bins/amd64
+
+docker buildx create --name multiarch --driver docker-container --platform linux/amd64,linux/arm64/v8 --use
+docker buildx build --push --platform linux/amd64,linux/arm64/v8 --tag thewawar/akasa:0.1.1 .
+```
+
+Just for one platform:
 ```shell
 docker build -t akasa:0.1.1 . --build-arg AKASA_ARCH="aarch64-unknown-linux-musl"
 docker image tag akasa:0.1.1 thewawar/akasa:0.1.1
