[GNC] UK - Self Assesment tax return

[TMG Services]

Hi all,
I run a small one man business in UK as self-employed. I started using
GNUCash, because of business growth. I managed to sort out imported QIF
data into GNUCash accounts and am ready to submit my Self Assesment tax
return but I found out I have no idea how to create any meaningful report
and it doesn't make much sense for me. I tried
https://github.com/cybermaggedon/ixbrl-reporter but it doesn't work and I,
as a handyman, not a programmer, am not able to fix it.

Is there any manual or video of how to do this? Can you please help?

Thank you very much for any input

Jacob
