#### FAQ
|
||||
|
||||
Q: Why does this module not work on Windows?
|
||||
A: As with many other things, Windows has a completely different and incompatible way of handling
|
||||
input parsing and drawing primitives, and support has not been implemented yet.
|
||||
Contributions are definitely welcome though.
|
||||
|
||||
Q: My terminal (doesn't receive events / doesn't print anything / prints gibberish characters),
|
||||
what's up with that?
|
||||
A: Please check if your terminal. The module has been tested with `xterm`-based terminals on Linux
