Possible to add info screen to SWEP?

What I mean is… for example… in DarkRP. The share prop tool. In the upper left corner of the screen it will display info and use.

if CLIENT then
language.Add( "Tool_shareprops_name", "Share tool" )
language.Add( "Tool_shareprops_desc", "Change sharing settings per prop" )
language.Add( "Tool_shareprops_0", "Left click: shares a prop. Right click unshares a prop")

I am making some cus
tom SWEPS and it would come in handy but when I copy/paste this bit nothing appears… no ERRORS… just… nothing happens.
