+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

 ## Setup
+Make sure that your host system has at least one WireGuard interface (for example wg0) available.
+If you did not start up a WireGuard interface yet, take a look at [wg-quick](https://manpages.debian.org/unstable/wireguard-tools/wg-quick.8.en.html) in order to get started.
 
 ### Docker

 ### Standalone

+For a standalone application, use the Makefile provided in the repository to build the application. Go version 1.18 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).
 
-## What is out of scope
+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`.
 
- * Generation or application of any `iptables` or `nftables` rules
- * Setting up or changing IP-addresses of the WireGuard interface on operating systems other than linux
- * Importing private keys of an existing WireGuard setup
+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.
+It is possible to override the configuration filepath using the environment variable **CONFIG_FILE**.
+For example: `CONFIG_FILE=/home/test/config.yml ./wg-portal-amd64`.

+### RESTful API
+WireGuard Portal offers a RESTful API to interact with.
+The API is documented using OpenAPI 2.0, the Swagger UI can be found
+under the URL `http://<your wg-portal ip/domain>/swagger/index.html?displayOperationId=true`.
+
+The [API's unittesting](tests/test_API.py) may serve as an example how to make use of the API with python3 & pyswagger.
+
+## What is out of scope
+ * Creating or removing WireGuard (wgX) interfaces.
+ * Generation or application of any `iptables` or `nftables` rules.
+ * Setting up or changing IP-addresses of the WireGuard interface on operating systems other than linux.
+ * Importing private keys of an existing WireGuard setup.
