 At this point, a special FTP account is automatically created for you to log in to the MassIVE-CA FTP server (**massive-ca-ftp.ucsd.edu**) to download the files associated with your dataset of interest. See our [FTP upload documentation](https://ccms-ucsd.github.io/MassIVEDocumentation/#upload_data/) for more information on the process of setting up an FTP client and connecting to the FTP server (although be sure to use the proper FTP host name for this controlled access download).

For now the files are kept encrypted at rest on our system, but our access workflow automatically decrypts them for you before serving them to your special request-specific FTP directory. We appreciate your patience as we harden and formalize our internal encryption workflow.

-Demo dataset access documentation coming soon.
+To facilitate easy testing of the MassIVE-CA [dataset access process](https://ccms-ucsd.github.io/MassIVEDocumentation/#massive-ca/access_data/), we have prepared a special demo dataset for you try out. We invite you to submit any questions or feedback you may have to [massive@ucsd.edu](mailto:massive@ucsd.edu).
+
+## Demo Dataset - caMSV000079841
+
+This demo dataset is a copy of the landmark Chick et al. database search dataset, originally submitted to PRIDE ([PXD001468](https://www.ebi.ac.uk/pride/archive/projects/PXD001468)) and mirrored at MassIVE ([MSV000079841](https://massive.ucsd.edu/ProteoSAFe/dataset.jsp?task=9101dafdf9d8484e86fac78cf7024b9f)) (original paper [here](https://www.nature.com/articles/nbt.3267)).
+
+To find this dataset in MassIVE-CA, simply navigate to the controlled access web portal ([https://massive-access.ucsd.edu/](https://massive-access.ucsd.edu/)), log in, and either enter the dataset's controlled-access accession in the "Search Dataset Identifiers or Public Metadata" search box, or click "MassIVE Datasets" at the top of the page and find the dataset there.

+
+Once the dataset's web page is loaded, you can review its metadata at your leisure just like in the public MassIVE repository. However, to access its files, you must submit an access request. To do this, simply click the "Request Access" button in the top left of the dataset page.
+
+![MassIVE-CA_demo_dataset](../img/massive-ca/MassIVE-CA_demo_dataset.png)
+
+This brings you to the access request input form, but with the dataset's caMSV accession pre-populated. From here simply follow the dataset access instructions to try out downloading an encrypted version of this dataset!
+
+> **NOTE:**  
+> Coming soon: Requesting access to this special demo dataset will be even easier, as all access requests will be granted automatically.
