Contributions are very welcome and encouraged. Here, we focus on contributions made via Github.
Before creating a new issue, please have a look at the list of existing issues to see if it already has been reported. An issue will be closed once it has been fixed in the source code. This fix however might not have its way to the version of Citykey you are using, so please don't forget to also check the closed issues.
If the problem you have found is not reported already, please create a new issue and describe what exactly you did to produce the faulty behavior mentioning the version of Citykey you are using. Screenshots are always welcome to illustrate your description.
If you want to do more than fixing bugs, please create an issue for the feature you want to work on (if it does not already exist) before doing any major work, so that other developers know about your plans, can coordinate, prevent duplicated work and discuss the best approach for your undertaking.
