Hi Peter,
All files and folders from the zip file has to be sent to your website.
Depend on how complex is your site, you could copy to your main folder
(often public_html) or create a folder for your weather Template.
That way, weather site could be join as this: MySite.com/weather
Only files you have to process are wt_data_inc.php and wt_month_inc.php
You could put these files to your Pc in a folder you whish. If some steps give
you problems, don't hesitate to post a line!
I've made simple step-by-step instructions to install each Template, just
follow these steps carefully.... things should go well!
