SEOMATIC v1.1.45 install Finally making progress into a production environment (Pro license installed) and I see that the SEOMATIC has an update - 1.1.45 - I followed the instructions but am lost, as SEOMATIC is already installed in my instance of Craft; instructions want me to install it...is there a step I am missing to get this update complete?

Please let me know what I am I missing here -- thank you a ton! =)

Thank you everyone for your answers! =)

If I am reading all the comments/answers correctly, I should do the following:
rm -R /var/www/html/craft/plugins/seomatic
cp -rv /home/psa/Zips/seomatic /var/www/html/craft/plugins
service apache2 restart

Is that correct? Thanks again for the assistance here!
To update plugins like SeoMatic, just download the latest (either clicking on the direct download link from the /admin/updates/ page in your admin area or from github).

Then you just then need to upload the new folder, overwriting the old one, to your server in the /craft/plugins directory (make sure you rename the download to seomatic as before, removing the '-master' that github adds).
