+CSS Support
+--------------------------------------------
+
+For now, only a subset of CSS properties are supported.
+
+The underlying C library MuPDF supports a subset of HTML4 and CSS2. The primary goal of the HTML/CSS support is to serve as a popular and convenient way to style text — not to faithfully reproduce websites in PDF.

 .. [#f1] MuPDF supports "deep-copying" objects between PDF documents. To avoid duplicate data in the target, it uses so-called "graftmaps", like a form of scratchpad: for each object to be copied, its :data:`xref` number is looked up in the graftmap. If found, copying is skipped. Otherwise, the new :data:`xref` is recorded and the copy takes place. PyMuPDF makes use of this technique in two places so far: :meth:`Document.insert_pdf` and :meth:`Page.show_pdf_page`. This process is fast and very efficient, because it prevents multiple copies of typically large and frequently referenced data, like images and fonts. However, you may still want to consider using garbage collection (option 4) in any of the following cases:

+~~~~~~~~~~~~~~~~~
 
-PDF to SVG
-~~~~~~~~~~~~~~~~~~
+As Markdown files are supported input files they can be easily converted to PDF using the :meth:`Document.convert_to_pdf` method.
 
-Technically, as SVG files cannot be multipage, we must export each page as an SVG.
+In the simplest case you can just open the Markdown file and call the method to get a PDF representation of the content. 
 
-To get an SVG representation of a page use the :meth:`Page.get_svg_image` method.
 
-**Example**
+Defining paper size
+"""""""""""""""""""
+
+The default paper size is 400 x 600 :doc:`rect` but you can specify a custom paper size if you wish, to do this just send through the `rect` parameter as required, for example:
 
 .. code-block:: python
 
-    import pymupdf
+    md_doc = pymupdf.open("example.md", rect=pymupdf.paper_rect("A4")) # A4 size
 
-    doc = pymupdf.open("input.pdf")
-    page = doc[0]
 
-    # Convert page to SVG
-    svg_content = page.get_svg_image()
+Defining CSS
+""""""""""""
+
+By default, the Markdown content will be converted to PDF using a default CSS stylesheet. However, you can specify your own CSS stylesheet to customize the appearance of the resulting PDF. To do this, define your `css` and apply it.
+
+For example, to make all ``h1`` headers red (The single ``#`` symbol in Markdown), you could do the following:
+
+.. code-block:: python
+
+    md_doc = pymupdf.open(  # open the Markdown document in A4 size
+        "example.md",
+        rect=pymupdf.paper_rect("A4")
+    )
+
+    css = "h1 {color:red;}"
+    md_doc.apply_css(css)
+
+    pdf_doc = pymupdf.open(stream=md_doc.convert_to_pdf())
+    pdf_doc.ez_save("red-colored-header.pdf")
+
+.. note::
+
+    The :ref:`support for CSS <CSS_Support>` is currently limited.
+
+
+Defining Fonts
+"""""""""""""""""
+
+Fonts can be defined by using the `archive` parameter to provide a custom :ref:`Archive` containing the font files.
+
+The fonts must exist in an archive which is provided to the `archive` parameter when opening the Markdown file. The CSS can then refer to these fonts by their names as defined in the archive.
+
+For example, assuming you have access to the source files for the "Comic Sans" font for all text, you could do the following:
+
+.. code-block:: python
+
+    # Global CSS instructions to use the "Comic Sans" font for all text. The font files must be provided in the archive.
+    css = """
+    @font-face {font-family: sans-serif; src: url(comic.ttf);}
+    @font-face {font-family: sans-serif; src: url(comicbd.ttf); font-weight: bold;}
+    @font-face {font-family: sans-serif; src: url(comicz.ttf); font-weight: bold; font-style: italic;}
+    @font-face {font-family: sans-serif; src: url(comici.ttf); font-style: italic;}
+    """
+
+    archive = pymupdf.Archive("C:/Windows/Fonts")  # the fonts are here
+    archive.add(".")  # we've stored the archive image in this script's folder
+
+    md_file = "sample.md"
+    md_doc = pymupdf.open(  # open the Markdown document
+        md_file,
+        archive=archive,  # where to look for resources (fonts, images)
+        rect=pymupdf.paper_rect("A4"),  # page dimension ISO A4
