+# Content
+
+Dockerfiles and scripts placed in this directory are intended to be used as
+development process vehicles and part of continuous integration process.
+
+Images built out of those recipes may be used with Docker or podman as
+development environment.
+
+# How to build docker image
+
+To build docker image on local machine execute:
+
+```sh
+docker build -t ur:ubuntu-22.04 -f ./ubuntu-22.04.Dockerfile .
+```
+
+To set any build time variable (e.g., an optional ARG from docker recipe), add to the command (after `build`), e.g.:
+
+```sh
+ --build-arg SKIP_DPCPP_BUILD=1
+```
+
+One other example of using these extra build arguments are proxy settings. They are required for accessing network
+(e.g., to download dependencies within docker), if a host is using a proxy server. Example usage:
+
+```sh
+ --build-arg https_proxy=http://proxy.com:port --build-arg http_proxy=http://proxy.com:port 
+```
+
+# How to use docker image
+
+To run docker container (using the previously built image) execute:
+
+```sh
+docker run --shm-size=4G -v /your/workspace/path/:/opt/workspace:z -w /opt/workspace/ -it ur:ubuntu-22.04 /bin/bash
+```
+
+To set (or override) any docker environment variable, add to the command (after `run`):
+
+```sh
+ -e ENV_VARIABLE=VALUE
+```
