How to install models to Gmod?

I know this seems like a really basic question but every single time I try to do this, It doesn’t work. Please help.

Files with a info text just go in addons

Files without the info file, the folders just get copied and pasted into your Gmod folder

How do I know if the have the info text or not?

When you open the files you should see the folders (Materials, LUA, models, settings,etc) and then you will see a notepad file called “Info”

Then I just put those in the addons folder?

When you extract the file, there should be a folder that contains all the stuff

Just place that folder into your addons

Thank you!
