Yes, basically just set the paths for SSLCertificateFile and SSLCertificateKeyFile in Apache to /etc/letsencrypt/live/example.domain.com/fullchain.pem and /etc/letsencrypt/live/example.domain.com/privkey.pem
Obviously replace example.domain.com with the domain that you got working with certbot. Your Apache config will then look like:
SSLCertificateFile /etc/letsencrypt/live/example.domain.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/example.domain.com/privkey.pem
I use it like this and works fine. In older versions of Apache you needed to use SSLCertificateChainFile as well, since the SSLCertificateFile couldn’t include the chain. But this now works in Apache, so only two lines are needed instead of three with the SSLCertificateChainFile.
