+# Hotdoc module
+
+This module provides helper functions for generating documentation using
+[hotdoc].
+
+*Added 0.48.0*
+
+## Usage
+
+To use this module, just do: **`hotdoc = import('hotdoc')`**. The
+following functions will then be available as methods on the object
+with the name `hotdoc`. You can, of course, replace the name `hotdoc`
+with anything else.
+
+### hotdoc.generate_doc()
+
+Generates documentation using [hotdoc] and installs it into `$prefix/share/doc/html`.
+
+**Positional argument:**
+
+* `project_name`: The name of the hotdoc project
+
+**Keyworded arguments:**
+
+* `sitemap` (*[string] or [file]*) (**required**): The hotdoc sitemap file
+* `index` (*[string] or [file]*) (**required**): Location of the index file
+* `dependencies`(*[targets]*): Targets on which the documentation generation depends on.
+* `subprojects`: A list of `HotdocTarget` that are used as subprojects for hotdoc to generate
+  the documentation.
+* ... Any argument of `hotdoc` can be used replacing dashes (`-`) with underscores (`_`).
+  For a full list of available parameters, just have a look at `hotdoc help`.
+
+[file]: Reference-manual.md#files
+[string]: Reference-manual.md#string-object
+[targets]: Reference-manual.md#build-target-object
+
+**Returns:**
+
+`HotdocTarget`: A [`custom_target`](Reference-manual.md#custom-target-object) with the
+following extra methods:
+
+* `config_path`: Path to the generated `hotdoc` configuration file.
+
+### hotdoc.has_extensions()
+
+**Positional arguments:**
+
+* `...`: The hotdoc extension names to look for
+
+**No keyworded arguments**
+
+**Returns:** `true` if all the extensions where found, `false` otherwise.
+
+### Example
+
+``` meson
+hotdoc = import('hotdoc')
+
+hotdoc.generate_doc('foobar',
+  project_version: '0.1',
+  sitemap: 'sitemap.txt',
+  index: 'index.md',
+  c_sources: ['path/to/file.c'],
+  c_smart_index: true,
+  languages: ['c'],
+  install: true,
+)
+```

+## Hotdoc module
+
+A new module has been written to ease generation of [hotdoc](https://hotdoc.github.io/) based
+documentation. It supports complex use cases such as hotdoc subprojects (to create documentation
+portals) and makes it straight forward to leverage full capabilities of hotdoc.
+
+Simple usage:
+
+``` meson
+hotdoc = import('hotdoc')
+
+hotdoc.generate_doc(
+  'foobar',
+  c_smart_index: true,
+  project_version: '0.1',
+  sitemap: 'sitemap.txt',
+  index: 'index.md',
+  c_sources: ['path/to/file.c'],
+  languages: ['c'],
+  install: true,
+)
+```
