+An example of a usable project can be found in the `example/` directory.  This example lambda function
 takes a JSON input file like event.json and returns an ASCII-art version of the text.
 
-```$ cd example/
+```
+$ cd example/
 ```
 
 The Dockerfile in the example directory loads the current workspace into the image and installs
 dependencies from the requirements.txt file:
 
-```FROM kilna/alpine-aws-python-lambda
+```
+FROM kilna/alpine-aws-python-lambda
 COPY . /workspace
 RUN pip install -r requirements.txt
 ```
 
 To build a docker image called 'example-lambda-image' with the lambda function in it, run:
 
-```$ docker build --tag example-lambda-image .
+```
+$ docker build --tag example-lambda-image .
 ```
 
 If you want to execute the lambda function against an event.json input file:
 
-```$ docker run example-lambda-image lambda invoke
+```
