First, make sure you have the latest version of Node.js and npm. We recommend using nvm to manage these, and there's a .nvmrc file in this project, so just run this and you're all set:

nvm use

Now you need to install the dependencies:

npm install

Then, in order to log your bot into Discord, set your bot token:

export DISCORD_TOKEN=<your discord app token>
# you could, instead, fill it in the ./settings.json file

And finally, start your bot with:

npm start
