+## About
 Openpixel is a customizable JavaScript library for building tracking pixels. Openpixel uses the latest technologies available with fall back support for older browsers. For example is the browser supports web beacons, openpixel will send a web beacon, if it doesn't support them it will inject a 1x1 gif into the page with tracking information as part of the images get request.
 
 At Dockwa we built openpixel to solve our own problems of implementing a tracking service that our marinas could put on their website to track traffic and attribution to the reservations coming through our platform.

 Openpixel has two parts, the snippet (`snippet.html`), and the core (`openpixel.min.js`).
 
-###Snippet
+### Snippet
 The openpixel snippet (found at `src/snippet.html`) is the HTML code that will be put onto any webpage that will be reporting analytics. For Dockwa, our marina websites put this on every page of their website so that it would load the JS to execute beacons back to a tracking server. The snippet can be placed anywhere on the page and it will load the core openpixel JS asynchronously. To be accurate, the first part of the snippet gets the timestamp as soon as it is loaded, applies an ID (just like a Google analytics ID, to be determined by you), and ques up a "pageload" event that will be sent as soon as the core JS has asynchronously loaded.
 
 The snippet handles things like making sure the core JavaScript will always be loaded async and is cache busted ever 24 hours so you can update the core and have customers using the updates withing the next day.

 The `src/snippet.js` file is what is compiled into the `dist/snippet.html` file. All of the other files in the `src` directory are compiled into the `dist/openpixel.js` and the minified `dist/openpixel.min.js` files.

 Below is a table that has all of the keys, example values, and details on each value of information that is sent with each beacon on tracking pixel. A beacon might look something like this. Note: every key is always sent regardless of if it has a value so the structure will always be the same.
