How to report bugs
Finesse is a complicated program and more than likely than not, there are some bugs in it.
- If you are part of the LVC please report bugs on the issues page (https://git.ligo.org/finesse/finesse/issues)
- If you are not in the LVC please send an email to firstname.lastname@example.org
In both cases please include all the files that are needed to replicate the error. If at all possible, also try and narrow the bug down. If you have a complicated file, try and simplify it as much as possible whilst still keeping the error. We'll try and fix it as soon as possible.
