 # BlogShot
 A bot that automatically polls the newest blogpost from [Hytale News Tab](https://www.hytale.com/news) and posts a message into servers if there is a new one.
-## Setup
-Okay, this isn't really meant for you to setup, if you want it though it first is easier to just dm me on Twitter [@tale_talk](https://twitter.com/tale_talk) so I can add you to the server list.
-If you *really* want to set it up yourself, fine.
-1. first go to the release tab, download the jar, and put it in a folder
-2. Add two files in the root of the repo, an `admin.json` and a `servers.json`.
+## Add to your server
+Click [this](https://discord.com/api/oauth2/authorize?client_id=743447329901641799&permissions=150528&scope=bot) link to invite
+the bot to your server. Please note that only people with *Administrator* permission will be able to
+configure it.

+* first go to the release tab, download the jar, and put it in a folder
+* Add two files in the root of the repo, an `admin.json` and a `servers.json`.
 Add your Discord ID (not name), Bot token, and update frequency to the `admin.json`:
 ```json
-{"adminId": 12345678910,"token": "AOGH@(AKnjsfjiJijaig3ijgG92jaij","updateMs":30000}

+  "token": "AOGH@(AKnjsfjiJijaig3ijgG92jaij",
+  "updateMs": 30000,
+  "watchingMessage": "for new Blogposts"
+}
 ```
-3. add an empty array to your `servers.json`
+* add your servers to `servers.json`
 ```json
-[]
+[
+  {
+    "id": 15050067772322222,
+    "mentionedRole": "everyone",
+    "autoPublish": true,

+    "autoPublish":false,
+    "message": null
+  }
+]
 ```
-Not sure, but it might be that multiline JSON doesn't work.
+* add a `test.json` with the same schema as the `server.json`. When
+you enable test mode, the servers from there will be used instead allowing
+you to test if it works.
