## Appendix J. Documentation

PostgreSQL™ has four primary documentation formats:

- Plain text, for pre-installation information

- HTML, for on-line browsing and reference

- PDF, for printing

- man pages, for quick reference.

Additionally, a number of plain-text `README` files can be found throughout the PostgreSQL™ source tree, documenting various implementation issues.

HTML documentation and man pages are part of a standard distribution and are installed by default. PDF format documentation is available separately for download.
