# Tournament data
This directory contains JSON files for tournament trees.
This is a temporary solution until the automatic tournament tree generation is completed.
# Structure
## Naming
Tournament name with `_` as separators and `.json` suffix.
## JSON structure
```json
{
"rounds": [
[
{
"opponent_1_id": 1,
"opponent_2_id": 2,
"winner": 1
},
{
"opponent_1_id": 3,
"opponent_2_id": 4,
"winner": null
}
],
[
{
"opponent_1_id": 1,
"opponent_2_id": null,
"winner": null
}
]
]
}
```
## ToDo
- Make start button in UI generate initial `.json` file for started tournament
