# DOCUMENTATION HOW-TO
**HTML Tidy** provides several types of documentation to suit different purposes. This
document describes how to generate the following:
- `tidylib_api/` (directory)
- This collection of documents describes the **TidyLib** API and is generated from the
comments and code in the **Tidy** source code.
- `quickref.html`
- This document provides a nice, readable HTML document describing all of the options and
settings that you can use with **Tidy** and internally in **TidyLib**.
- `tidy.1`
- This document is a Mac/Linux/Unix standard `man` page.
## The easy way
In this directory you can find the shell script `build_docs.sh`, and that will build all
of the documentation into the `temp/` directory (i.e., `{tidy}/build/documentation/temp`).
Please note these prerequisites:
- It's a Mac/Linux/Unix shell script.
- Doxygen is required to generate the API documentation.
- xsltproc is required to generate the man page and the `quickref.html` file.
If you prefer to understand how to do this manually (for example, for integration into
other scripts, build systems, or IDEs), read on.
## Manually
### `tidylib_api/` (directory)
If you want to build the API documentation you must have [doxygen][1] installed.
You can clone the [repository from github][2] if it is not currently installed.
Building as simple as:
~~~
cd {tidy}/build/documentation/
doxygen doxygen.cfg
~~~
This will result in a document set in `{tidy}/build/documentation/temp/tidylib_api`,
where you can find the main `index.html` file.
### `quickref.html`
Note that these instructions require the standard `xsltproc` utility to build the file,
but any XSLT processor of your choice should work, too.
- `tidy -xml-config > "tidy-config.xml"`
- This uses your up-to-date version of **Tidy** to generate an XML file containing all
of **Tidy**s built-in settings and their descriptions. This file is only temporary,
as it will be transformed in the next step.
- `xsltproc "quickref.xsl" "tidy-config.xml" > "quickref.html"`
- This examples uses the `xsltproc` command to transform `tidy-config.xml` using the
rules in the `quickref.xsl` stylesheet, and output it to `quickref.html`.
### `tidy.1`
Note that these instructions require the standard `xsltproc` utility to build the file,
but any XSLT processor of your choice should work, too.
- `tidy -xml-config > "tidy-config.xml"`
- This uses your up-to-date version of **Tidy** to generate an XML file containing all
of **Tidy**s built-in settings and their descriptions. This file is only temporary,
as it will be transformed in the third step.
- `tidy -xml-help > "tidy-help.xml"`
- This uses your up-to-date version of **Tidy** to generate an XML file containing all
of **Tidy**s built-in help information. This file is only temporary,
as it will be transformed in the next step.
- `xsltproc "tidy1.xsl" "tidy-help.xml" > "tidy.1"`
- This examples uses the `xsltproc` command to transform `tidy-help.xml` using the
rules in the `tidy1.xsl` stylesheet, and output it to `tidy.1`.
Note that `tidy1.xls` includes the file `tidy-config.xml` as part of the stylesheet,
and so although it does not appear in the command invocation, it is indeed required.
