Add basic new to tshock section

(The markdown preview system I'm using seems to be lying to me,
so I want to see what this looks like with gfm for one commit).

+1. Download [the latest stable version](https://github.com/TShock/TShock/releases) and `unzip` the folder using your favorite unzip tool. Make sure that all of the files in the zip get into one folder. This is where your server will be stored. The file structure looks like this:
+
+      
+          GeoIP.dat
+          Newtonsoft.Json.dll
+          OTAPI.dll
+          ServerPlugins\
+          |------BCrypt.Net.dll
+          |------HttpServer.dll
+          |------Mono.Data.Sqlite.dll
+          |------MySql.Data.dll
+          |------TShockAPI.dll
+          TerrariaServer.exe
+          sqlite3.dll
+      
+
+1. Start `TerrariaServer.exe` and TShock will boot. Answer the startup questions, and you should be ready to roll. In the background, TShock made some folders for you. We'll come back to those later.
+
+1. Startup Terraria. Connect to a `multiplayer` server via IP and enter `localhost` if you're doing this on your local computer. If you're doing it on another computer, you need its IP address.
+
+1. Look at the server console for the _auth code_. Type `/auth [code]` (example: `/auth 12345`), then a space, then the code you see in the console in your game chat. Instead of chatting, you'll run a command on the server. This one makes you temporary admin. All commands are prefixed with `/` or `!` (to make them silent).
+
+1. Use the in-game command `/user add [username] [password] owner` (example: `/user add shank ashes owner`) to create an account. This gives you owner rights on your server, which you can configure more to your liking later.
+
+1. Login to your newly created account with `/login [username] [password]` (example: `/login shank ashes`). You should see a login success message.
+
+1. Turn off the backdoor with `/auth` and your server is setup for initial use!
