<h3>Setup Guide</h3>

<p>

Welcome to Janrain Engage for Wordpress. This guide will help you get this plugin setup.

<br>

Use of this plugin requires an Engage application. Janrain offers Engage applications at 

 multiple service levels and with prices starting at $0. Please visit our 

 <a href="http://www.janrain.com/products/engage/features-comparison" target="_blank">feature comparison page</a>

 to find the service level that is right for your site(s).

</p><p>

Once you  

 <a href="https://rpxnow.com/" target="_blank">sign in</a> to your Engage application you 

 can easily access the API key to enable the plugin.

</p>

<h3>Sign In Setup</h3>

<p>

Copy the API key from the Application Info on the main page of your Engage dashboard and paste 

 into the API key option on the Setup panel for Janrain Engage on your Wordpress admin dashboard.

 Click the Save Settings button; the plugin will retrive the needed settings from the Engage system 

 and save those settings for you. This will unlock the full set of options.

</p><p>

Setup the sign in providers on <a href="https://rpxnow.com/" target="_blank">Engage</a>. Select 

 the sign-in for web settings. Skip to the Choose Providers step. Drag and drop your desired

 providers into the widget. If a provider has a grey gear icon it will require setup steps on

 that provider's website. When you drag the provider or click the gear you will be offered a 

 setup guide to walk you through enabling the provider. Click save when you are done.

</p><p>

After you click save you will see a link to allow you to test the widget. Please test each provider 

 to ensure that everything works. Providers that offer an email address will work best with 

 Wordpress due to the requirement for email addresses for each user. Check the 

 <a href="https://rpxnow.com/docs/providers" target="_blank">provider guide</a> to familiarize 

 yourself with what each provider offers in the data returned.

</p><p>

Add your site domain to the token URL domain list. Click the settings option on your Engage 

 dashboard to access the page with the allowed domain list. Add your domain and click save.

</p><p>

Back to the Wordpress Janrain Engage Setup page. Clicking save will update the icons shown to 

 your visitors. Click it a second time if needed.

</p><p>

The verfiedEmail match setting allows existing users to get automatically connected to thier 

 existing account if possible. This is not needed for a new site. There are some security concerns 

 around this feature. Do not enable this if security is a top concern. This feature does not work 

 to connect to the admin account (id 0). If you would like to connect this account to Engage please 

 do so via the profile page for that user.

</p><p>

The login link for comments feature can be confusing. This feature adds an Engage login prompt to

 the comment area. There are many template action hook options for this area and you may need to 

 experiment or examine the template source to find the correct option. For a template that is up to

 WP3 standards the main question is if you require sign in or not. If you do you will want the hook 

 named comment_form_must_log_in, and if not you will likely want comment_form_before_fields.

</p><p>

The plugin includes a Wordpress Sidebar Widget. Look in Appearance -&gt; Widgets to find this widget.

</p><p>

If none of these options are working you may want to look at using a shortcode in your template. 

<br>See the shortcode page for more info.

</p><p>

Hint: 

<br><em>To set a language for the widget you can use the expert option for additional URL parameters.

<br>(e.g. language_preference=fr would set French)</em>

</p>

<h3>Registration Setup</h3>

<p>

Enable automatic user registration if your blog is not using user registration customizations or 

 supplimentary user registration forms (such as BuddyPress). This feature will enable your visitors 

 register and sign in very quickly if they have a full profile shared from the Engage sign on.

</p>

<h3>General User Experience Setup</h3>

<p>

Enable social provider icons to display the avatar from the Engage provider instead of the generic 

 Wordpress icons.

</p>

<h3>Social Sharing Setup</h3>

<p>

Setup the social providers on <a href="https://rpxnow.com/" target="_blank">Engage</a>. Select 

 the social sharing for websites panel. Skip to the Choose Providers step. Drag and drop your desired

 providers into the widget. These providers will require setup steps on each provider's website. 

 When you drag the provider or click the gear you will be offered a setup guide to walk you through 

 enabling the provider. Click save when you are done.

</p><p>

<p>

Enable social sharing and click save changes to reveal the full options. These options are intended 

 to work with fully up to date WP3 templates. The JS for this widget looks for an img element with 

 id="rpxshareimg" and adds this image to the share if found.

 <br>Enable the count bubbles to track and display counters for each successful share per provider.

 <br> (counts are not tracked if this feature is not enabled)

 <br>

 <br>If you are having trouble getting these options to work you may need to add shortcodes to your 

 template. See the shortcode page for more info.

<br>

The share widget button can be displayed as a row of icons or as a text link.
