To proceed with the installation the first thing to do is to know the location of the .zip file that we will have downloaded from the store. 

Knowing the exact location we go to Blender and in the menu Edit > Preferences, we will open a preferences window with a left side section. 

In that section we will look for the section called Addons and instantly we will be able to see a huge list of all the available addons. 

In the upper right part of that same window, we will find the Install button. Click on it and a new file navigation window will appear. 

We will proceed to go to the location where we have saved our addon. Remember that the format of the addon is a .zip file.  We will locate it and select it, then we will click on the Install-Addon button. 

If everything went well, the Addon will appear in the list, marked as activated and with the preferences part compacted. 

We will be able to open it to see what preferences we have available. 

It should now be correctly installed.
