# Conky docs
There are 3 YAML files which contain the documentation:
* [`variables.yaml`](variables.yaml): Documents each object/variable
* [`config_settings.yaml`](config_settings.yaml): Documents global configuration settings
* [`lua.yaml`](lua.yaml): Documents Conky's Lua API
The `desc` field within the docs can be formatted with markdown, however _do
not_ include headings within the `desc` fields, as it will mess up the man page
output. In markdown, headings begin with `#`.
The supported documentation fields are:
* `name`: the name of the thing
* `desc`: a markdown-formatted description of the thing
* `args`: optional list of arguments
* `default`: an optional default value, if applicable
## Updating docs
The man page is based on [`man.md.j2`](man.md.j2) which is a Jinja2 template.
The generated markdown is used to generate a final man page using
[`pandoc`](https://pandoc.org/). Generating the final man page is a 2 step
process:
1. Run `docgen.py` to process `man.md.j2`:
```console
$ ./docgen.py man.md.j2 > man.md
```
2. Run `pandoc` to convert the markdown into a man page:
```console
$ pandoc -f markdown -t man.md > conky.1
```
These steps are also part of the CMake build, and can be executed by configuring
the build with `-DBUILD_DOCS=ON`.
