+## How to run Docker image on local machine
+ 1. Make sure you have docker engine installed: `docker --version`
+ 2. If there is no docker, please install it this way ):
+    ```sh
+    apt update && apt install -y apt-transport-https ca-certificates curl software-properties-common
+    curl -sSL https://get.docker.com/ | sh
+    ```
+ 3. Pull and run container by the following command (use correct image for your case):
+    ```sh
+    # Find top level dir of the git project:
+    WORKSPACE=$(git rev-parse --show-toplevel)
+
+    # run ubuntu2004 image on x86_64:
+    docker run -it -d --rm --privileged -e WORKSPACE=$WORKSPACE -v $WORKSPACE:$WORKSPACE -v /var/lib/hugetlbfs:/var/lib/hugetlbfs --ulimit memlock=819200000:819200000 -v /auto/mtrswgwork:/auto/mtrswgwork -v /hpc/local/commercial:/hpc/local/commercial -v /auto/sw_tools/Commercial:/auto/sw_tools/Commercial -v /hpc/local/etc/modulefiles:/hpc/local/etc/modulefiles harbor.mellanox.com/swx-infra/x86_64/ubuntu20.04/builder:mofed-5.2-2.2.0.0 bash
+
+    # run toolbox image on x86_64:
+    docker run -it -d --rm --privileged -e WORKSPACE=$WORKSPACE -v $WORKSPACE:$WORKSPACE -v /var/lib/hugetlbfs:/var/lib/hugetlbfs --ulimit memlock=819200000:819200000 -v /auto/mtrswgwork:/auto/mtrswgwork -v /hpc/local/commercial:/hpc/local/commercial -v /auto/sw_tools/Commercial:/auto/sw_tools/Commercial -v /hpc/local/etc/modulefiles:/hpc/local/etc/modulefiles harbor.mellanox.com/toolbox/ngci-centos:7.9.2009.2 bash
+    ```
+ 4. Login to running docker image:
+    ```sh
+    docker exec -it ${IMAGE_NAME} bash
+    ```
+Navigate to `$WORKSPACE` directory inside the image
