+## Running containers
+
+```docker run --rm -it -v $(pwd):/mnt/dev <container_name>```
+
+## Building and pushing to Container Registry
+
+### Preparation
+
+1. Login to container registry with your git credentials
+
+    ```docker login gitlab.keith-koep.com:5050```
+
+### Build and push
+
+1. Navigate to the directory of the container you want to build
+
+2. Build with 
+
+    ```docker build docker build -t gitlab.keith-koep.com:5050/imx/uboot-imx:<flavour, which is a directory name> .```
+
+    or with prepared script
+
+    ```./build.sh```
+
+3. Push with 
+
+    ```docker push gitlab.keith-koep.com:5050/imx/uboot-imx:<flavour, which is a directory name>```
+
+    or with prepared script
+
+    ```./push.sh```
+
+4. You can rebuild the container without using build cache with
+
+```docker build --no-cache -t gitlab.keith-koep.com:5050/imx/uboot-imx:<flavour, which is a directory name> .```
+
+
+## Build multi-arch containers
+
+### Preparation steps
+
+1. Check which builders are available
+
+    ```docker buildx ls```
+
+2. Create a custom builder `kuk-builder`
+
+    ```docker buildx create --name kuk-builder default```
+
+
+3. Choose this bulder to use by default
+
+    ```docker buildx use kuk-builder```
+
+
+### Build and push
+
+1. Build and push with
+
+    ```docker buildx build --platform linux/amd64,linux/arm64 -t gitlab.keith-koep.com:5050/imx/uboot-imx:<flavour name> --push . ```
+
+    or with prepared script
+
+    ```./build-multiarch-and-push.sh```
