+# CaffeOnSpark Standalone Docker
+
+Dockerfiles for CPU build is provided in `standalone/cpu` folder. The image can be built by running:
+```
+docker build -t caffeonspark:cpu standalone/cpu
+```
+After the image is built, use `docker images` to validate.
+
+## Launching CaffeOnSpark container
+Hadoop and Spark are essential requirements for CaffeOnSpark. To ensure that both process runs flawless, we have included `standalone/cpu/config/bootstrap.sh` script which must be run everytime the container is started.
+
+To launch a container running CaffeOnSpark please use:
+```
+docker run -it caffeonspark:cpu /etc/bootstrap.sh -bash
+```
+
+Now you have a working environment with CaffeOnSpark.
+
+To verify installation, please follow [GetStarted_yarn](https://github.com/yahoo/CaffeOnSpark/wiki/GetStarted_yarn) guide from `Step 7`.
