## Corrections and Updates

Corrections to these documents can be submitted as patch files to the EPICS core
developers, or as merge requests or pull requests to the 3.15 branch of Base.
The document sources can be found in the `src/std/rec` and `src/ioc/db`
directories in files with extension `.dbd.pod`. The documentation source format
is a combination of the EPICS DBD file format with an extended version of Perl's
POD (plain old documentation); run `perldoc pod` for details of POD.
