+# hydrabot
+Hydrabot is an open-source bot made with the intents of demonstrating the capabilities of [discord.js](https://github.com/hydrabolt/discord.js/).
+
+### Set up
+The easiest setup would be to clone the discord.js repo, and then open a terminal/cmd in this directory and run `node hydrabot.js`.
+
+If you don't want to clone the repo but instead just use this folder, you need to edit `hydrabot.js` to use `require("discord.js")` as opposed to `require("../")`. Cloned directories will always be using the latest **discord.js**.
+
+### Setting up credentials
+
+Edit `config.json` to use your Discord email and password, and then run `node hydrabot.js`.
