## Sample functions
We have packaged some simple starter functions in the Docker stack, so as soon as you open the OpenFaaS UI you will see them listed down the left-hand side.
Deploy the sample functions by deploying the `stack.yml` file in the `faas/` repo folder:
```
faas deploy
```
You don't need to specify a `-f` or `--yaml` option to the `faas` command. By default the `stack.yml` file is used if it is present.
Here are a few of the functions:
