+# Data Analytics Reference Stack
+
+This provides the Data Analytics Reference Stack. To offer more flexibility,
+there are two versions of the Data Analytics Reference Stack:
+
+* A Clear Linux derived image optimized for [OpenBLAS](https://www.openblas.net/)
+* A Clear Linux derived image optimized for Intel® Math Kernel Library [MKL](https://software.intel.com/en-us/mkl)
+
+Please see the folders in this level about the variants and how to build and use them.

+### Building Locally
+
+Default build args in Docker are on: https://docs.docker.com/engine/reference/builder/#arg
+
+```
+docker build --no-cache -t clearlinux/stacks-dars-mkl .
+```
+
+### Build ARGs
+
+* `swupd_args` specifies [swupd update](https://github.com/clearlinux/swupd-client/blob/master/docs/swupd.1.rst#options) flags passed to the update during build.
+
+>NOTE: An empty `swupd_args` will default to Clear Linux OS latest version. Consider this when building from the Dockerfile, as an OS update will be performed. The docker image in this registry was built and validated using version 29200.
