[OSM-talk] tutorial for mapping buildings?

[Mateusz Konieczny]

"but may not explain in the project instructions how a "non-standard" building should be mapped"

Especially in areas where such buildings are typical it is failure on HOT side and
should be remediated on their side. If someone is looking for newbies and instructing
them to edits it is their responsibility to provide necessary instructions to avoid ending
with poor edits. I am quite surprised that this problem was not spotted so far by them,
given HOT focus on building geometries.

Though making some easy to use documentation would be useful in general.
