Submit bug reports or feature requests
Just use the GitHub issue tracker to submit your bug reports and feature requests.
If you are submitting a bug report, please remember to include:
Your complete Appium log (as a gist---do NOT paste the whole thing into the issue description).
This will tell us the exact version of Appium and the exact capabilities you are using, so you don't have to.Your relevant client code, if you are able to share it (again a gist is most useful).
Any other information helpful in trying to reproduce your issue.
In general, the less work we have to do to reproduce a bug, the faster we will fix it. So please include as much information as possible up front!
