## How can I get more information when something is going wrong?
Cointop creates a logfile at `/tmp/cointop.log`. Normally nothing is written to this, but if you set the environment variable
`DEBUG=1` cointop will write a lot of output describing its operation. Furthermore, if you also set `DEBUG_HTTP=1` it will
emit lots about every HTTP request that cointop makes to coingecko (backend). Developers may ask for this information
to help diagnose any problems you may experience.
```bash
DEBUG=1 DEBUG_HTTP=1 cointop
