+This is an example of creating a deployment package with multiple
+files including some static data in text file.
+
+### Create an environment
+
+```
+fission env create --name python --image fission/python-env:0.4.0rc --version 2
+```
+
+### Create a zip file with all your files
+
+```
+zip -jr multifile.zip *.py *.txt
+```
+
+### Create a function
+
+Since there are multiple files, you have to specify an _entrypoint_ to
+for the function.  Its format is `<file name>.<function name>`. In our
+example, that's `main.main`, to run function `main` in `main.py`.
+
+```
+fission function create --name multifile --env python --code multifile.zip --entrypoint main.main
+```
+
+### Test it
+
+```
+fission function test --name multifile
+```
+
+You should see the "Hello, world" message.
+
+
+## Updating the function
+
+### Edit a file
+
+```
+echo "I said hellooooo!" > message.txt
+```
+
+### Update the deployment package
+
+```
+zip -jr multifile.zip *.py *.txt
+```
+
+### Update the function
+
+```
+fission function update --name multifile --code multifile.zip
+```
+
+### Test it
+
+```
+fission function test --name multifile
+```
+
+You should now see your new, edited message.
