How to publish a forge app in JIRA?

Question

Hai all,
    I have three questions.
1. If i created one forge app, How can i publish that app in JIRA atlassian marketplace?
2. If publish a forge app in JIRA atlassian marketplace is possible then how can i install the app in my JIRA instance?
3. Is there any way to create custom installation page for an app? For example while installing i need to get some input from the user and i need to do validation. After enter the right details only the user can install an application in their instance. Is it possible?

Thanks in advance..

Hai Daniel Eads,
    I can get your point. But only problem for my organisation is EAP still in progress only. I need a valid point if i go with forge app.

The Early Access Program for Forge marketplace listings is still active as of this moment. However, according to the What's Next section of the Forge announcement post , it's expected to move into general availability very soon. The process to submit an app for approval under the EAP is really not significantly different than doing it for production purposes. Details are here.

For data storage, check out the concepts in the documentation. The Forge Issue Alerting app is a reference app you can use to see the App Storage API in action.

Hai Daniel Eads, 
    Really thanks for your suggestion. My only concern to build forge app is publish this app in atlassian marketplace and app needs to be available whenever i want. You mention about the Early Access Program. It's not completed yet right?
You mention that we can store data in settings page. If it's possible can you share any document to do that?

Thanks in advance..
