👍🎉 Thank you for taking the time to contribute something to the Firefly III Data Importer!
First of all: thank you for reporting a bug instead of ditching the tool altogether. If you find a bug, include as many log files and details as you think are necessary. Bugs have a lot of priority!
Please take the time to read the documentation of Firefly III or the documentation of the data importer (TODO) and make sure you search through closed issues for the problems other people have had. Your problem may be among them! If not, open an issue, and I will help where I can.
