# Greenhouse
Greenhous control
## Installation
```shell
python setup.py install
```
## Usage
### Manual
Create wrapper script (e.g. wrapper.py):
```python
from greenhous import app
if __name__ == "__main__":
app.run()
```
Execute the wrapper script:
```shell
python3 wrapper.py
```
### gunicorn
```shell
gunicorn --bind 0.0.0.0:80 greenhouse:app
```
