Local running of Terraform

[sturner11]

When trying to run the terraform locally before I pushed my work to github, I ran into a problem with the file lambda.zip. The workflow creates this file automatically when it runs, but the terraform won't work without it. I don't know how common it is to run terraform init and plan before pushing changes to github, but I usually do especially when I am creating something new. I would recommend including the need to create the zip file somewhere in the readme when getting things going locally, if that is considered useful.
