## Reporting bugs
Prefered way to report a bug is to open an issue on GitHub. If not possible,
you can also contact the development team directly with an e-mail.
Please look also at detailed instructions here [here](doc/REPORTING-BUGS.md).
For general questions, ideas or remarks you are encountered to use the project's
[GitHub Discussions](https://github.com/CESNET/UltraGrid/discussions).
## Feature requests
Feature requests can be submitted with the same channels as bugs.
## Pull requests
Pull request should be issued as a single branch originating from repository
master branch, preferably rebased to current version. If multiple features are
created, multiple pull requests containing every single feature should be
issued.
## Coding standards
**TODO:** incomplete
### Style
Recommended style is modified LLVM clang-format style:
```
BasedOnStyle: LLVM
IndentWidth: 8
BreakBeforeBraces: Linux
````
The style is deduced from original _rtp/rtp.{c,h}_ formatting and it
is similar to [Linux Kernel
style](https://www.kernel.org/doc/Documentation/process/coding-style.rst)
(see [here](https://clang.llvm.org/docs/ClangFormatStyleOptions.html#examples))
without using tabs.
### Naming conventions
Logged module name (`MOD_NAME`) should be lower-case.
## Conclusion
Aside of what is enumerated above, we will be glad if you share with us your
setup, photos or just ideas.
