+You can either download prebuild binaries from the [release page](https://github.com/h44z/wg-portal/releases) or use Docker images for ARM. 
+If you want to build the binary yourself, use the following building instructions.

 ### Building
 This section describes how to build the WireGuard Portal code.
 To compile the final binary, use the Makefile provided in the repository.
 As WireGuard Portal is written in Go, **golang >= 1.16** must be installed prior to building.
+If you want to cross compile ARM binaries from AMD64 systems, install *arm-linux-gnueabi-gcc* (armv7) or *aarch64-linux-gnu-gcc* (arm64).

 ```
-make build-cross-plat
+# for 64 bit OS
+make build-arm64
+
+# for 32 bit OS
+make build-arm 
 ```

 The compiled binary and all necessary assets will be located in the dist folder.

 Please note that mapping ```/etc/wireguard``` to ```/etc/wireguard``` inside the docker, will erase your host's current configuration.

 ### Standalone
 For a standalone application, use the Makefile provided in the repository to build the application. Go version 1.16 or higher has to be installed to build WireGuard Portal.

-```
+```shell
+# show all possible make commands
 make

-# To build for arm architecture as well use:
-make build-cross-plat
+# build wg-portal for current system architecture
+make build
 ```

 The compiled binary will be located in the dist folder.
 A detailed description for using this software with a raspberry pi can be found in the [README-RASPBERRYPI.md](README-RASPBERRYPI.md).

+To build the Docker image, Docker (> 20.x) with buildx is required. If you want to build cross-platform images, you need to install qemu.
+On arch linux for example install: `docker-buildx qemu-user-static qemu-user-static-binfmt`.
+
+Once the Docker setup is completed, create a new buildx builder: 
+```shell
+docker buildx create --name wgportalbuilder --platform linux/arm/v7,linux/arm64,linux/amd64
+docker buildx use wgportalbuilder
+docker buildx inspect --bootstrap
+```
+Now you can compile the Docker image:
+```shell
+# multi platform build, can only be exported to tar archives
+docker buildx build --platform linux/arm/v7,linux/arm64,linux/amd64 --output type=local,dest=docker_images \
+  --build-arg BUILD_IDENTIFIER=dev --build-arg BUILD_VERSION=0.1 -t h44z/wg-portal .
+  
+
+# image for current platform only (same as docker build)
+docker buildx build --load \
+  --build-arg BUILD_IDENTIFIER=dev --build-arg BUILD_VERSION=0.1 -t h44z/wg-portal .
+```

 ## Configuration
 You can configure WireGuard Portal using either environment variables or a yaml configuration file.
 The filepath of the yaml configuration file defaults to **config.yml** in the working directory of the executable.
