Hi all, someone was kind enough to share this model with me and how to use it and being very new with the program, I am having trouble understanding the process

I have done the tutorial on introducing a new model, but cant see how to use this text data below in the tutorial steps. I would like to request someone show me how to use this information to enable a triode symbol on the LTspice work area in a mini tutorial please

Thanks and regards
Randy
