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:

> [tag:app] http://stackapps.com/questions/ask?tags=app

> [tag:library] http://stackapps.com/questions/ask?tags=library

> [tag:script] http://stackapps.com/questions/ask?tags=script

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.][1]

These questions provide a default template for you to work with. Please follow this rough template; it's presented below for reference.

<pre>
&lt;!-- thumbnail: http://example.com/some-image.png --&gt;
&lt;!-- version: 1.0 --&gt;
&lt;!-- tag: a-tag-on-the-post --&gt;
&lt;!-- excerpt: Up to 200 characters of excerpt --&gt;

###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?
</pre>

###Metadata

Thumbnails should be <b>144 pixels wide, and 119 pixels tall</b> and a <a href="http://en.wikipedia.org/wiki/Portable_Network_Graphics">PNG file</a> (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 [tag:app],[tag:library], or [tag: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.

**Note by George Edison:** I have written [a script](http://stackapps.com/questions/3118/stack-apps-listing-wizard-making-it-easier-to-list-your-application-right-here) that will automatically generate markdown in the format above for your application by guiding you through a wizard. You can install the script by clicking [here](http://files.quickmediasolutions.com/userscripts/stackapps_listing.user.js). Then simply click the new icon that appears on the editing toolbar when you ask a new question.
