Step 5. Before moving forward, I recommend your to get a microSD card and put the SuperSu 2.65 zip on there. Download this TWRP image too.

First you will have to flash the TWRP image, using Command Prompt or Terminal:

As soon as you see the LG logo, let of the power button then quickly press it again. But keep volume down pressed! Do not let it!

Hold until you will see the Factory Reset screen.

Step 7. install SuperSU Root

The last step, is to install the root by installing SuperSU. Note that you will not be able to decrypt your internal data while in TWRP, only if you do a full /data wipe in TWRP.

Now you can manually mount your external SD card to view the SuperSu zip. Click the Install button and navigate to the external_sd, select the SuperSu.zip then swipe to install.

Now you have successful installed a Custom Recovery TWRP and fully rooted your LG G5. Have fun and note that it is really difficult to restore your device to stock ROM. Note that the root would be automatically removed once you update your Android version.
