This document provides steps to install an SSL certificate from a .pem file. It explains that a .pem file contains the SSL certificate and is given by a Certificate Authority after generating a Certificate Signing Request (CSR). The steps are: 1) use OpenSSL to extract the certificate from the .pem and private key files into a .p12 file; 2) install the .p12 certificate; and 3) verify the certificate is installed by checking the certificate store.
