STOP BEING IDIOTS! If you don't know how to open the console or bind stuff to a key, then you don't deserve to have this addon.

Shielder 1.1 - Created by Dlaor

This is a portable shield addon, which spawns numerous shields around you which will orbit you to maximize protection!

To install: place the shielder folder in your garrysmod/addons folder. It's that simple.
To upgrade: do the same as above. If it asks to overwrite, hit "Yes".
To use: type shielder_menu in the console to open the Shielder main menu, where you can change all of its settings.

You can also bind it to a key by typing this in your console:
bind n shielder_menu
And then change n to any key you like.
