A good starting point is the reference documentation:

https://bind9.readthedocs.io/en/latest/chapter4.html#developing-plugins

Then, a more detailed explanation can be found in the long comment
header in `lib/ns/include/ns/hooks.h`

After reading those two things, I'd suggest looking at a dummy plugin
in the test code:

`bin/tests/system/hooks/driver/test-syncplugin.c`

What this test plugin is doing is not important, but you can see the
various hooks points implemented as an example.

And finally we currently support 3 plugins, you can find the code in

`bin/plugin/*.c`

Thanks,
