CM12 is however a custom ROM so you should understand that you aren’t going to flash an OTA Lollipop firmware on your Galaxy S5 LTE. The update is provided by third party devs and shouldn’t be related in any matter with Samsung or with Google.

The update process can be easily completed, but the installation operation should be considered risky and complex. If messing things up you can brick your Samsung Galaxy S5 before being able to test and enjoy CM 12 custom ROM. Therefore, stick to the guidelines from below, even if you are an advanced Android user.
