+# Overview
+In this folder, we create the different dockerfiles for using pykoi.
+
+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.
+
+To run a docker container, we can use the following command:
+```bash
+docker run -dp 5000:5000 -v $(pwd)/app.py:/app/app.py \
+        --name alex_test \
+        pykoi/pykoi-cpu:app
+```
+
+Note that we need to keep the exposed port as 5000 (default value) to make the server work.
