# Haddock, a Haskell Documentation Tool [![Build Status](https://travis-ci.org/haskell/haddock.svg?branch=master)](https://travis-ci.org/haskell/haddock)
-#### About haddock
+## About haddock
-This is Haddock, a tool for automatically generating documentation
-from annotated Haskell source code. It is primary intended for
-documenting library interfaces, but it should be useful for any kind
-of Haskell code.
+See [Description on Hackage](https://hackage.haskell.org/package/haddock).
-Haddock lets you write documentation annotations next to the
-definitions of functions and types in the source code, in a syntax
-that is easy on the eye when writing the source code (no heavyweight
-mark-up). The documentation generated by Haddock is fully hyperlinked
-- click on a type name in a type signature to go straight to the
-definition, and documentation, for that type.
+## Source code documentation
-Haddock understands Haskell's module system, so you can structure your
-code however you like without worrying that internal structure will be
-exposed in the generated documentation. For example, it is common to
-implement a library in several modules, but define the external API by
-having a single module which re-exports parts of these implementation
-modules. Using Haddock, you can still write documentation annotations
-next to the actual definitions of the functions and types in the
-library, but the documentation annotations from the implementation
-will be propagated to the external API when the documentation is
-generated. Abstract types and classes are handled correctly. In
-fact, even without any documentation annotations, Haddock can generate
-useful documentation from your source code.
-
-
-#### Documentation formats
-
-Haddock can generate documentation in multiple formats; currently HTML
-is implemented, and there is partial support for generating LaTeX and
-Hoogle.
-
-
-#### Source code documentation
-
-Full documentation can be found in the doc/ subdirectory, in DocBook
+Full documentation can be found in the `doc/` subdirectory, in
+[reStructedText format](http://www.sphinx-doc.org/en/stable/rest.html)
format.

+The `master` branch usually requires a GHC from the latest GHC stable
+branch. The required GHC version can be inferred from the version
