Default [Q] Recovery Mode (No command?)

Hello people

I have a rooted LG G2 device and I wanted to download a custom ROM, and so I installed "Rom Manager" and installed the "Team Win" Recovery thingy. After that I wanted to go into recovery mode and used "Rom Manager" in order to do so but It showed up w/ a Green Android with a Red Triangle and said "No Command".... What does that mean and how can I fix it? Thanks Homies

Device Info:

LG G2 Verizon Variant
Android 4.2.2
Software Version: VS98012B
Model Number: VS980 4G
