# Developer docs

Contributor, developer, and maintainer docs.
These aim to describe and communicate the structure, processes and
workflows of the hledger project - "the machine that makes the machine".

These mostly are kept in doc/ in the main hledger repo,
and then symlinked into the hledger_site repo for rendering on hledger.org.
