Use the oik-fum flexible update manager to direct WordPress to look for updates on other servers
oik-fum activates the logic within the oik base plugin to look for plugin updates from alternative servers.
If you have developed a plugin that is not integrated with the oik API then you can use this plugin to activate the base functionality within the oik base plugin to check for plugin updates from an oik-plugins server.
The oik flexible update manager is a companion plugin to the oik base plugin.
It’s probably one of the simplest ways you can use to support your plugin from a server other than WordPress.org
Ideal for testing your plugin’s updates before you make them available publicly.
