I'm trying to deploy a project to Google App Engine. The main HTML page I render is stored in the /documents/form.html directory of the project. If I run on my local host it finds the file no problem. When I deploy to GAE it gives the below error: 

```
File "/base/data/home/apps/s~andesonchase/1.372703354720880550/main.py", line 4, in <module>
    fileHandle = open("documents/form.html", "r")
IOError: [Errno 2] No such file or directory: 'documents/form.html'

```

I think I need to include it on my app.yaml but I'm not sure on the correct syntax.
