The great thing about WeaverBox is that all the complicated code and configuration is done automatically for you behind the schemes. This makes WeaverBox relatively easy to setup in a project.
Open your project in RapidWeaver and click on the Add Page button. From the list of installed plugins, choose WeaverBox from the list (plugins are arranged alphabetically). At this stage, a new page gets added called Untitled Page or similar in the webpages list on the left.
Double-clicking the page title enables you to rename the page to something more relevant. Likewise in the RapidWeaver Page Inspector, the browser title, file name and folder name of the page can be changed if you wish. Under the header tab, you could optionally add some META tags, like a description or keywords, to aid search engines finding your page.
IMPORTANT - The page extension of your page should remain .php and must not be changed back to .html or modified to anything else.
