+### Running as a Docker container
+Assuming that you have Docker installed, and a valid API key, a Docker image
+can be created using the follwing steps:
+* Clone this repository and cd to the directory
+
+* Build the Docker image (Here `crypto_app` is the name of the generated image)
+```bash
+docker build --build-arg api_key=<YOUR_API_KEY> -t crypto_app .
+```
+
+* Once the image is successfully generated, start a container (port 8010 is hard-coded
+in the Dockerfile, can also be changed if needed):
+```bash
+docker run -dp 127.0.0.1:8010:8010 crypto_app
+```
+
+* Check log output:
+```bash
+docker logs --follow <container id>
+```

 First plot will take a few seconds to appear, wait patiently! If you are running this app for the
 first time, or on a different date, new data will be retrieved from Alpha Vantage, and then saved
 to CSV files on disk. Keep in mind that the free API key imposes a limit of five calls/minute,
