Simple color picker input maker. Every time it's used. It will append to existing container.
((d)=>{
let z=d.querySelector("#__z");
if (!z) {
z = d.createElement("div");
z.setAttribute("id", "__z");
z.setAttribute("style", "z-index: 999999; padding: 1em; position:fixed; display:flex; width:100vw; top: 0px; left:0px; align-items: center; flex-direction: row; flex-wrap: nowrap; align-content: space-around; justify-content: center; ");
d.body.appendChild(z);
}
let e=d.createElement("input");

Last active January 18, 2022 16:19 — forked from chrisswanda/WireGuard_Setup.txt
Stupid simple setting up WireGuard - Server and multiple peers

Install WireGuard via whatever package manager you use. For me, I use apt.

$ sudo add-apt-repository ppa:wireguard/wireguard
$ sudo apt-get update
$ sudo apt-get install wireguard
