This is a plugin to allow the easy entry of microformat content for recipes (i.e. the hRecipe microformat) in WordPress pages and posts.
Unzip the plugin into your wp-content/plugins/ directory. It should automatically create an hrecipe/ subdirectory.
In your WordPress admin page, go to the Plugins section and Activate the "hRecipe Support for Editor" plugin.
When you go to "Write Post" or "Write Page", click on the star logo to pop-up a simple form.
Fill in the fields of the form, particularly the name of the thing you are reviewing.
Click Insert and the contents of the fields will be inserted into the page or post you were composing, but marked up using the hReview microformat.
