 ## Contributors
 
 **Without your help this project would not be possible**. I (@xoseperez) simply can't spend all the time I wish on ESPurna but luckly I recieve a lot of contributions, bug fixes, enhancement suggestions,... from people all around the world. I would like to thank each and every one of you. The [contributors](https://github.com/xoseperez/espurna/graphs/contributors) page shows the ones that have done a PR in the past, but I also get contributions in the issues, by email or via the [gitter ESPurna channel](https://gitter.im/tinkerman-cat/espurna), those I also want to thank.
