I have a question regarding the installation step 4.
Place the following snippet where you want the stars to appear (normally single.php, content-single.php or index.php):
I'm not sure where to place the snippet...? Do I have to open the file for example index.php and where exactly to place it then?
Or do I have to create an own document with my editor and to place this document that contains the snippet ONLY into a folder?
Your help would be really great I haven't done this type of installation before! And finally it seems easy.
