If you're looking for technical documentation of the XML format, there is a MozillaWiki page for it here, but this is likely out of date as most of those fields are no longer used. An xml as we serve now looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<updates>
<update type="minor" displayVersion="2000.0a1" appVersion="2000.0a1" platformVersion="2000.0a1" buildID="21181002100236">
<patch type="complete" URL="http://127.0.0.1:8000/<mar name>" hashFunction="sha512" hashValue="<hash>" size="<size>"/>
</update>
</updates>
Some of this is redundant; displayVersion, appVersion and platformVersion are usually going to be the same, and I don't think we distinguish between minor and major update types anymore.
You may find this MDN article helpful from a practical perspective if you're trying to serve your own updates: Setting up an update server
There is a wiki article for the MAR file structure which I think is accurate.
We have bug 1616403 on file for generally improving the documentation around the updater. If you have any specific questions please feel free to ask, but I'll close this for now as this is not really a support forum.
