+This dsicord bot downloads videos from [nicovideo.jp](https://www.nicovideo.jp/), 
+provides color roles, role reactions and proxied pins
+
+USAGE
+---
+Set up a discord application with bot associated https://discord.com/developers/docs/intro ; note the discord bot token.
+
+Run as `./jaroid -c config.yml`
+
+Bot implementation requires a redis server to store persistent configuration and queues
+
+Config 
+---
+
+Example structure
+
+```yaml
+private:
+  token: "<discord bot token>"
+  prefix: "!"
+  redis:
+    address: "127.0.0.1:6379"
+    password: ""
+    db: 0
+  nicovideo:
+    directory: "/home/somewhere/public/nicovideo"
+    public: "http://example.com/nicovideo"
+    period: "24h"
+    auth:
+      username: ""
+      password: ""
+```
+
+`!nico.download` will place files in `nicovideo.directory` and post a link using `nicovideo.public` as base, hence directory
+should be served by some HTTP server.
+
+Example nginx configuration:
+```
+server {
+  server_name example.com;
+  listen 80;
+
+  root /home/somewhere/public/nicovideo;
+  
+  location / {
+    autoindex on;
+  }
+}
+```
+
+Setting up a feed
+---
+
+```
+!nico.feed <name> <period> <channelID> <search filter>
+```
+
+e.g. !nico.feed cookie 1h 1234567890 クッキー☆
