Usage
Creating a Package
At the bottom of the WordPress admin side bar you will see WP Update Provider. Open it and click add new.
To create a package you need to supply its name and slug. Slug needs to match the slug clients will use.
Releasing a Version
Using the dashboard
When viewing a package there is a file uploader in which you can place a ZIP file. This file will be uploaded and parsed through the same system as the CI uploader.
Using CI
WUP-Client provides a function to send builds from your CI.
