+# Docker Image for Python Examples
+---
+### Summary
+To simplify the running of the Python examples, the Dockerfile will build an image and install the latest rosette-api library.
+
+### Basic Usage
+Build the docker image, e.g. `docker build -t basistech/python:1.1 .`
+
+Run an example as `docker run -e API_KEY=api-key -v "path-to-example-source:/source" basistech/python:1.1`
+
+To test against a specific source file, add `-e FILENAME=filename` before the `-v`
+
+Also, to test against an alternate url, add `-e ALT_URL=alternate_url` before the `-v`
