Build your ss installation - in browser visit following url:

http://your-ss-installation/dev/build

Setup in SiteConfig area

In backend visit SiteConfig area, tab Disqus, place required data:

• disqus shortname (from your disqus account)
• disqus secret key (from your disqus account)
• disqus prefix (place there anything you want. Store diferent prefix for local and production, so thread identifier will be different and your local testing comments will not be shown on production.) By default, identifier looks like this: prefix_pageID. You can customize this for each Page (Behaviour tab, right above Comments checkbox) so you can show same comments on multiple pages (alternatively, create different forum for local copy of your site)...
• Disqus sync time -> comments can be synced with disqus server for SS usage (e.g. generate comments for non javascript usage, search, latest comments listing...). Place time in seconds (3600 for 1 hour)
• By default, time syncing works as standard php process within visitor's page load (so if there are some difficulties with disqus server connection, page load can be limited). You can enable background syncing, so syncing is independent from visitor's page load. Its alpha feature, tested only on linux!

Activate in your theme

Replace

$PageComments

with following code

$DisqusPageComments

if you are on some Page holder (list of pages), you can show comments count by adding:

<% if disqusEnabled %>$disqusCountLink<% end_if %>

Usage

If default comments module installed:

Check SS default Enable Page Comments Checkbox (located in Settings tab) to enable disqus comments

Else

Comments will be shown on all pagetypes activated in comments.yml
