Can't find out how to upgrade from 3.1.0-rc2 to 3.1.1

Sorry if i missed it but i couldn't find out how to upgrade from 3.1.0-rc2 to 3.1.1.
It didn't made it itself from inside joomla, i did download the file, but what do i do?
must i delete the previous installation before or just upload the new file?
To tell the truth i find some difficulty moving around at the doc and the forum and google terns me up many answers in French witch unfortunately i don't speak.

Hello

We added Joomla update check support on v3.1.0+, so after you upgrade to v3.1.1, you will start get these checks

For downloading new version:

In this website , in our top menu:
Downloads / Latest version


Or direct link:
www.flexicontent.org/downloads/latest-version.html

Or on github:
github.com/FLEXIcontent/flexicontent-cck/releases

Thank U for answer!
Happy Christmas Day!
I have downloaded the latest version but what i don't know is how to continue.
The site is running on a server and it is not on local host.
I have the 3.1.0-rc2 version.
In order to upgrade at the 3.1.1. version, keeping my content untuched, how should i proceed?
I upload the .zip file as it is and it goes to upgrade the old version by it self?
Thanks again!

Hello

yes you just upload the ZIP file via Joomla installer
never uninstall, because uninstall deletes flexicontent DB tables
