+To build the base docker container run
 ```bash
 hekit docker-build
 ```
+This will build a base image containing the necessary dependencies and then an
+image containing the HE Toolkit repository with the `hekit` command enabled.
+This can be useful as a base for users to use the HE Toolkit to build a subset
+of the provided sample kernels and examples or an entirely custom HE project of
+their choosing.
+
+If a full installation of the sample kernels, examples, and supported HE
+libraries is desired then build the Intel HE Toolkit container in its entirety
+with
+```bash
+hekit docker-build --enable samples
+```
 The installation should take a few minutes and once successful will run the
 container as the current user. This will be signified with the printing of the
 welcome message to the console.

 base image that it fetches from dockerhub if it does not exist locally. This
