+## `netlify functions:create`
+
+Create a new function from a given template.
+
+Examples:
+
+```
+netlify functions:create
+netlify functions:create hello-world
+netlify functions:create --name hello-world
+netlify functions:create hello-world --dir
+
+```
+
+You can just call `netlify functions:create` and the prompts will guide you all the way, however you can also supply a first argument to name the function. By default it creates a single file, however you can also use a `--dir` flag to create a function as a directory.
