+# FormFile
+
+`FormFile` is a custom component wrapper around the Bootstrap-vue Form File component. The purpose of this component is to upload files to the BMC.
+
+To use this component:
+1. Import it into the single file component (SFC)
+2. Add the `<form-file />` tag
+3. Add the optional `id` , `disabled`, `accept` and `state` prop as required
+
+[Learn more about the Bootstrap-vue Form File component](https://bootstrap-vue.org/docs/components/form-file)
+### Optional properties
+
+- `id`- Used to set the `id` attribute on the rendered content, and used as the base to generate any additional element IDs as needed
+- `disabled` - When set to `true`, disables the component's functionality and places it in a disabled state
+- `accept` - Set value to specify which file types to allow
+- `state` - Controls the validation state appearance of the component. `true` for valid, `false` for invalid, or `null` for no validation state
+
+## Example of form file
+
+```vue
+<form-file
+  id="image-file"
+  accept=".tar"
+  >
+</form-file>
+```
