+## Upload Version Button Component (Workaround)
+
+Activates a file version upload.
+Until further backend API improvements, this component is meant to be used to enrich the feature of node version uploading and to decrease the restrictions currently applied to the node version upload.
+
+```html
+<adf-upload-version-button
+    staticTitle="Upload new version"
+    [node]="node"
+    [rootFolderId]="node.parentId"
+    [versioning]="true"
+    (success)="onUploadSuccess($event)"
+    (error)="onUploadError($event)">
+</adf-upload-version-button>
+```
+
+### Properties
+
+Since UploadVersionButtonComponent extends UploadButtonComponent, the properties are the same. Note that some properties doesn't make sense in case of version upload button, thus are just simply ignored. For the version upload button the **node** (which is about to be versioned) is a mandatory input parameter.
+
+### Events
+
+Since UploadVersionButtonComponent extends UploadButtonComponent the properties are the same.
+
+### Restrictions
+At the moment the API only allows new version uploads for a node, if the name of the new version is exactly the same as the old version (**and most importantly the extension**). Because of it, this workaround component uploads the chosen file with the same name as what the original file had (that is the reason, the **node** is a mandatory dependency for this component).
+
+So at the end what this component can and can not do:
+
+**Can**:
+- upload a new version from the same file extension regardless of the file name.
+
+**Can not**:
+- upload a new version which has a different file extension, than what the originally uploaded file had. (an error message is emitted on the error EventEmitter of the component).
