If you've created an application, script, or library for use on the Stack Exchange network, that's fantastic!
Now publicize it by creating a question with the correct tag:
Generally, you should only publicize your app if it can actually be used, but to develop a write-access app, you will need to set up a placeholder post first.
These questions provide a default template for you to work with. Please follow this rough template; it's presented below for reference.
<!-- thumbnail: http://example.com/some-image.png --> <!-- version: 1.0 --> <!-- tag: a-tag-on-the-post --> <!-- excerpt: Up to 200 characters of excerpt --> ###About: (required) Tell us about your app/library/wrapper/script. Why did you create it? Who is it for? How does it work? What problem does it solve? ###Screenshot / Code Snippet: (highly recommended) Insert a reasonably sized screenshot (or code snippet) of your app/wrapper/library/script here, so we can get a quick look at it and an idea of how it works and what it might do for us. ###Download / Install: (required) Provide links for us to obtain your app/library/wrapper/script. For websites or service, provide link to the main or home page. A user should be able to jump to this section and dive right into your app. ###Platform: (recommended) What platform or browser is your app/library/wrapper/script for? Android? PC? Mac? Apple Newton? Firefox? Opera? Lynx? ###Contact: (optional) Who created this app? Who are the key contributors? How do we get in touch with them or find them? ###License: (optional) What license is your app/library/wrapper/script released under, if any? Or if it is paid, how much does it cost and how do we buy it? ###Code: (recommended) What language, frameworks, and tools were used to write this? Where can we get the code? How can we contribute to the code?
Thumbnails should be 144 pixels wide, and 119 pixels tall and a PNG file (with extension). If no thumbnail is provided, one will be generated from the first image in the question if possible; a default will be used if nothing is provided.
The designated tag will be the "+1 tag" that is shown in addition to the app,library, or script tags. If it is not specified explicitly, the most popular tag on the post will be used instead. If a tag is explicitly designated, it must exist on the post to take effect.
The version number will not be displayed if omitted.
The excerpt cannot contain any HTML or markup. If it is omitted, the first ~200 characters of the About section will be included. If there is no About section, the first ~200 characters of the post itself will be used.
