Every event is a `.md` file with the following metadata tags:
#### Required
* title: String
* time: Date
* location: String
#### Optional
* banner: URL
### Grouped events
If there's a series of events (for example summer code nights) these can be grouped by creating a folder containing a `main.md`, which will need the following metadata:
#### Required
* title: String
#### Optional
* location: String
* banner: URL
Other `.md` files made in that folder are sub-events which need to fit the [metadata description listed earlier](#metadata)
