What do you need help with?

I have downloaded Baritone 1.15.2 from the YouTube link on the main GitHub page. After some research I was still not able to find a way to upload schematics into the game files. I tried making a folder labelled 'schematica' and putting it in there. When I tried to run the command "#build modern-house-2" it says "couldn't load the schematic", and when I use "#schematica" it says "Schematica is not present". Would I have to download schematica separately and somehow put it into baritone, if so how?
Thank you

You need to include the full file name for building. Also schematica doesn't exist for 1.15
