 # Building Custom Docker Images
-In this folder, we create the different dockerfiles for using pykoi.
+In this folder, we have the different Dockerfiles for using `pykoi`.
+
+## Building from the Repo
+Some of these examples build from the pykoi repository. For example, you can reference the Dockerfile in the `pykoi-retrieval-huggingface`.
+
+In order to build the docker image, first ensure you are in the base directory of the `pykoi` repo. __You will encounter errors if you're not in the base directory__
+
+Then, you can run the following command:
+```
+docker build -t [name]:[tag] . -f [file_path_to_dockerfile]
+```
+
+Here's and example of building the `pykoi-retrieval-huggingface` Dockerfile.
+```
+docker build -t pykoi:0.1 . -f docker/pykoi-retrieval-huggingface/Dockerfile
+```
+
+## Building based on pykoi library
+There are also examples to build based on the `pykoi` package. These examples install `pykoi` via `pip` and run different applications from there. This relies on the latest pypi released versions.
 
 1. `pykoi-cpu`: The base image for the cpu-based usage.
-2. `pykoi-cpu-custom`: When you run this docker image, try to modify the `app.py` and mount it when running the docker container.
