It is designed to be very simple to the front-end user-they will typically handle a couple of png files and then select a new downloader from a list-but very flexible (and hence potentially complicated) on the back-end. After the maintenance burden of the entire messy system proved too large for me to keep up with and a semi-editable booru system proved successful, I decided to overhaul the entire thing to allow user creation and sharing of every component. The first versions of hydrus's downloaders were all hardcoded and static-I wrote everything into the program itself and nothing was user-creatable or -fixable. Beware! If you are simply looking for how to add new downloaders, please head over here.

Creating custom downloaders is only for advanced users who understand HTML or JSON.
