Install and go!  Make sure it loads AFTER the weather mod you've selected during install (i.e. load this after PureWeather)<br />

<br />

NMM / MO -- This uses a FOMOD installer, so just download, activate, and choose which weather mod you're using, if any.  NLA version requires Natural Lighting and Atmospherics weather plugin to be installed!  If it isn't in your load order, you will get a CTD upon loading (missing master.)<br />

<br />

MANUAL -- Copy the data from 00 - Core Files to your /data/ folder, and copy the ESP from the folder of the weather you're using (the folder and file names are very obvious)
