"Use samples" "Upload samples" for a button?

It's a web app that allows you to translate text files you upload.

If you don't have any files to upload but want to test the app we allow you to use some samples.

They aren't added to the project by default because few users need them. Most people upload their own files.

So, the upload page has 2 buttons:

upload files and use samples.

Once the user clicks the button - 3 sample files will appear. Once the user clicks Upload files he/she can choose files from the machine.

Question: how to better name the "use samples" button?
