Adding context links

Navigate to Administer > Site Building > Context > Add (admin/build/context/add)
Name can be the same as your feature, or similarly named. Not sure what the best naming strategy is here, but same as feature name hasn't caused problems.
Under Conditions, select 'Node type' from drop down list
Scroll through the list that appears to right, and check the node types in your particular feature. Multiple node types in your feature? Select all that you want to have 'Add this CT' buttons for.
Are you using a view to output your feature content? If so, under Conditions select 'Views' from the drop down list. Just like the node selection you just did, scroll through the list of views and check the view names that are used in your feature.
Under Reactions select 'Menu' from the drop down list. Then, in the menu drop down list that appears to the right, find the 'Features' section and select the name of your feature.
Hit the Save button.
EITHER: Drush: drush features-update yourfeaturename
OR: visit Features, click Recreate for your feature, add the contexts that you just created, download feature, re-upload feature.
Clear cache, you should have those cute black buttons to create the feature's content type, and only on the appropriate page(s).
