and browse to the mod_jvweather.zip file and click "upload"
Next, you will need to publish/activate the module into a position that your template supports. This is done from within the Module Manager.
For Joomla! 1.5, navigate to Extensions > Module Manager and click the ZooTemplate module (ex: mod_jvweather) to access its options.
Some templates may have a suitable module position for the ZooTemplate modules, however you may want to publish ZooTemplate so that it will appear by itself in the main content area of the Joomla! site. If this is you, then follow these instructions for creating a module position.
