-## Packaging
+## Next Steps
 
-Packaging a function is essentially just creating a Docker image for your function with an ENTRYPOINT.
-
-The basic Dockerfile for most languages is something like this:
-
-```
-# Choose base image
-FROM iron/go
-# Set th working directory
-WORKDIR /function
-# Add your binary or code to the working directory
-ADD hello /function/
-# Set what will run when a container is started for this image
-ENTRYPOINT ["./hello"]
-```
