+Curii operates a public demonstration instance of Arvados called the Arvados Playground, which can be found at <a href="https://playground.arvados.org" target="_blank">https://playground.arvados.org</a> . Some examples in this guide involve getting data from the Playground instance.

+h2. Logging in
You will be asked to log in. Arvados uses only your name and email address for identification, and will never access any personal information. If you are accessing Arvados for the first time, the Workbench may indicate your account status is *New / inactive*. If this is the case, contact the administrator of the Arvados instance to request activation of your account.
