# Attaching a document type to a dataset
{% hint style="info" %}
Document types can only be attached to datasets by Administrators.
{% endhint %}
Document types can be assigned as 'Attach 'Document' questions to datasets, allowing Administrators to specify what kind of document is expected of a Researcher to upload in order for them to access that data.
### How to attach a document type to a dataset
1. Select 'Admin tools' from your username dropdown.
2. Select 'Datasets'.
3. Select 'Manage' from the row of the dataset you wish to attach a document type to.
4. Select the 'Request requirements' tab.
5. Navigate to the 'Document Type' section, and select 'Add'.
6. Select the document type you wish to attach from the 'Document' dropdown.
**Note:** Document types can be removed from this dataset once added by selecting the checkbox beside them, then 'Delete selected' (below).
7. **If you wish to add more document types**, repeat steps 5-6. **If you have added all of the document types you wish to attach to this dataset**, navigate to the bottom of the 'Request requirements' tab and select 'Save'.
8. The added document types can now be used for 'Attach Document' questions when a researcher makes a data request for the relevant dataset.
