+# @frontside/backstage-plugin-humanitec-scaffolder-backend-module
+
+`@frontside/backstage-plugin-humanitec-backend` is a plugin for the Backstage backend app. It provides a route that `@frontside/backstage-plugin-humanitec` will use to connect to Humanitec API and scaffolder actions.
+`@frontside/backstage-plugin-humanitec-scaffolder-backend-module` is a new backend system module to add the humanitec action in the scaffolder
+
+## Scaffolder Actions
+
+This plugin provides the following scaffolder actions,
+
+### create-app
+
+`create-app` will create an app in Humanitec with specific workloads and automation. 
+
+#### Installation
+
+TBD
+
+...
+
+
+4. Add configuration to `app-config.yaml`
+
+```diff
+humanitec:
+  orgId: the-frontside-software-inc
+  token: ${HUMANITEC_TOKEN}
+```
+
+### Usage
+
+Add the action to your template,
+
+```diff
++    - name: Create Humanitec App
++      id: humanitec-create-app
++      action: humanitec:create-app
++      input:
++        setupFile: humanitec-apps.yaml
++        appId: ${{ parameters.componentName }}
+```
+
+### setupFile parameter
+
+`humanitec:create-app` needs to know what workloads to create in the Humanitec App. In the future, workload configuration will be handled using [paws.sh](https://paws.sh), in the mean time, `humanitec:create-app` expects to read an YAML file where it expects to find information about the payload. By default, this file is called `humanitec-app.yaml` and can be changed by specifying `setupFile` parameter.
+
+Here is an example of such a file,
+
+```yaml
