+## Building the Merlin Containers Locally
+
+Building our containers is a two-step process. We first build the Merlin `BASE_IMAGE` using the `dockerfile.merlin` file. This container depends on two upstream containers: `nvcr.io/nvidia/tritonserver` and `nvcr.io/nvidia/tensorflow`, from which it pulls the necessary dependencies for Triton Inference Server and RAPIDS tools. It also builds and installs other Merlin requirements, such as scikit-learn, XGBoost, etc.
+
+We then build framework-specific containers based off of the `BASE_IMAGE`. See the table above for which Dockerfile corresponds to which framework-specific container.
+
+The base image is not made available publicly, but the framework-specific containers based on it are. The two-stage build process takes roughly 1 hour. Running all of the tests for all Merlin libraries can take a couple of additional hours, depending on which framework you're building.
+
+## Building The `BASE_IMAGE`
+
+We tag this image as `nvcr.io/nvstaging/merlin/merlin-base:${MERLIN_VERSION}` and it is used to create the framework-specific containers. There are `ARG`s in the Dockerfile to define which version of the containers to use. You can override the defaults when building the image like below.
+
+```bash
+docker build -t nvcr.io/mycompany/merlin-base:${MERLIN_VERSION} --build-arg TRITON_VERSION=23.04 - < docker/dockerfile.merlin
+```
+
+In this example we are tagging the base image as `nvcr.io/mycompany/merlin-base:${MERLIN_VERSION}`. The tag Merlin uses when building this image in our own build pipeline is `nvcr.io/nvstaging/merlin/merlin-base:${MERLIN_VERSION}`. 
+
+## Building A Framework-Specific Container
+
+We also provide Dockerfiles for creating framework-specific containers: `dockerfile.tf`, `dockerfile.torch`, and `dockerfile.ctr`. These are all based on the `BASE_IMAGE` created in the previous step and install the associciated deep learning frameworks.
+
+To build the PyTorch container, we specify the `BASE_IMAGE` build arg to use the base image that we just created.
+
+```bash
+docker build -t ngcr.io/mycompany/merlin-torch:${MERLIN_VERSION} --build-arg BASE_IMAGE=nvcr.io/mycompany/merlin-base:${MERLIN_VERSION} - < docker/dockerfile.torch
+```
+
+## Default Arguments
+
+Each of the Dockerfiles have many `ARG`s defined, most of which have defaults set. Sometimes the defaults fall out of date, because the Merlin team overrides them in our build process as demonstrated above. To see the `ARG` values used in each of our released containers, see the [Merlin Support Matrix](https://nvidia-merlin.github.io/Merlin/main/support_matrix/index.html)
