In order to download Subs, you need to first have the [Apple Testflight app](https://apps.apple.com/us/app/testflight/id899247664). Once you've downloaded the Apple Testflight app, open the Subs Testflight link on your iPhone. This should prompt you to install the **Subs: Trade Your Interests beta** app. Open the Subs app, and go through the sign up flow. * If you sign up through email, you will receive a code to your email from Privy. * If you sign up through X, you will need to authorize the connection. After this step (not before), you will be prompted for your Subs invite code. ## Android [Subs on the Google Play store](https://play.google.com/store/apps/details?id=fun.subs.app) Open the Subs app, and go through the sign up flow. * If you sign up through email, you will receive a code to your email from Privy. * If you sign up through X, you will need to authorize the connection.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.subs.fun/help/redeeming-invite.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
