+Quickstart
+----------
+
+Install blag from PyPI_
+
+.. code-block:: sh
+
+    $ pip install blag
+
+.. _pypi: https://pypi.org/project/blag/
+
+Run blag's quickstart command to create the configuration needed
+
+.. code-block:: sh
+
+    $ blag quickstart
+
+Create some content
+
+.. code-block:: sh
+
+    $ mkdir content
+    $ edit content/hello-world.md
+
+Generate the website
+
+.. code-block:: sh
+
+    $ blag build
+
+By default, blag will search for content in ``content`` and the output will be
+generated in ``build``. All markdown files in ``content`` will be converted to
+html, all other files (i.e. static files) will be copied over).
+
+If you want more separation between the static files and the markdown content,
+you can put all static files into the ``static`` directory. Blag will copy
+them over to the ``build`` directory.
+
+If you want to customize the looks of the generated site, create a
+``template`` directory and put your jinja2 templates here.
+
+Those directories can be changed via command line arguments. See
+
+.. code-block:: sh
+
+    $ blag --help
+
+
+Manual
+------
+
+
+Pages and Articles
+^^^^^^^^^^^^^^^^^^
+
+Internally, blag differentiates between **pages** and **articles**.
+Intuitively, pages are simple pages and articles are blog posts. The decision
+whether a document is a page or an article is made depending on the presence
+of the ``date`` metadata element: Any document that contains the ``date``
+metadata element is an article, everything else a page.
+
+This differentiation has consequences:
+
+* blag uses different templates: ``page.html`` and ``article.html``
+* only articles are collected in the Atom feed
+* only articles are aggregated in the tag pages
+
+blag does **not** enforce a certain directory structure for pages and
+articles. You can mix and match them freely or structure them in different
+directories. blag will mirror the structure found in the ``content`` directory
+
+::
+
+    content/
+        article1.md
+        article2.md
+        page1.md
+
+results in:
+
+::
+
+    build/
+        article1.html
+        article2.html
+        page1.html
+
+Arbitrary complex structures are possible too:
+
+::
+
+    content/
+        posts/
+            2020/
+                2020-01-01-foo.md
+                2020-02-01-foo.md
+        pages/
+            foo.md
+            bar.md
+
+results in:
+
+::
+
+    build/
+        posts/
+            2020/
+                2020-01-01-foo.html
+                2020-02-01-foo.html
+        pages/
+            foo.html
+            bar.html
+
+
+Static Files
+^^^^^^^^^^^^
+
+Static files can be put into the ``content`` directory and will be copied over
+to the ``build`` directory as well. If you want better separation between
+content and static files, you can create a ``static`` directory and put the
+files there. All files and directories found in the ``static`` directory will
+be copied over to ``build``.
+
+::
+
+    content/
+        foo.md
+        bar.md
+        kitty.jpg
+
+results in:
+
+::
+
+    build/
+        foo.html
+        bar.html
+        kitty.jpg
+
+Alternatively:
+
+::
+
+    content/
+        foo.md
+        bar.md
+    static/
+        kitty.jpg
+
+results in:
+
+::
+
+    build/
+        foo.html
+        bar.html
+        kitty.jpg
+
+
+Internal Links
+--------------
+
+In contrast to most other static blog generators, blag will automatically
+convert **relative** markdown links. That means you can link you content using
+relative markdown links and blag will convert them to html automatically. The
+advantage is that your content tree in markdown is consistent and
+self-contained even if you don't generate html from it.
+
+
+.. code-block:: markdown
+
+   [...]
+   this is a [link](foo.md) to an internal page foo.
+
+becomes
+
+.. code-block:: html
+
+   <p>this is a <a href="foo.html">link</a> to an internal page foo.</p>
+
+
+Templating
+----------
+
+Custom templates are **optional** and stored by default in the ``templates``
+directory. blag will search the ``templates`` directory first, and fall back
+to blag's default built-in templates.
+
+============ ====================================== ===================
+Template     Used For                               Variables
+============ ====================================== ===================
+page.html    pages (i.e. non-articles)              site, content, meta
+article.html articles (i.e. blog posts)             site, content, meta
+archive.html archive- and landing page of the blog  site, archive
+tags.html    list of tags                           site, tags
+tag.html     archive of Articles with a certain tag site, archive, tag
+============ ====================================== ===================
+
+If you make use of Jinja2's template inheritance, you can of course have more
+template files in the ``templates`` directory.
+
+``site``
+    This dictionary contains the site configuration, namely: ``base_url``,
+    ``title``, ``description`` and ``author``. Don't confuse the site-title
+    and -description with the title and description of individual pages or
+    articles.
+
+``content``
+    HTML, converted from markdown.
+
+``meta``
+    ``meta`` stands for all metadata elements available in the article or
+    page. Please be aware that those are not wrapped in a dictionary, but
+    **directly** available as variables.
+
+``archive``
+    A list of ``[destination path, context]`` tuples, where the context are
+    the respective variables that would be provided to the individual page or
+    article.
+
+``tags``
+    List of tags.
+
+``tag``
+    A tag.
+
+
+Metadata
+---------
+
+blag supports metadata elements in the markdown files. They must come before
+the content and should be separated from the content with a blank line:
+
+.. code-block:: markdown
+
+    title: foo
+    date: 2020-02-02
+    tags: this, is, a, test
+    description: some subtitle
+
+    this is my content.
+    [...]
+
+blag supports *arbitrary* metadata in your documents, and you can use them
+freely in you templates. However, some metadata elements are treated special:
+
+``date``
+    If a document contains the ``date`` element, it is treated as an
+    **article**, otherwise as a **page**. Additionally, ``date`` elements are
+    expected to be in ISO format (e.g. ``1980-05-05 21:58``). They are
+    automatically converted into ``datetime`` objects with the local timezone
+    attached.
+
+``tags``
+    Tags are interpreted as a comma separated list. All elements are stripped
+    and converted to lower-case: ``tags: foo, Foo Bar, BAZ`` becomes: ``[foo,
+    foo bar, baz]``.
+
+    Tags in **articles** are also used to generate the tag-pages, that
+    aggregate all articles per tag.
+
+``title`` and ``description``
+    The title and description are used in the html header and in the atom
+    feed.
+
+
+Devserver
+---------
+
+blag provides a devserver which you can use for local web-development. The
+devserver provides a simple web server, serving your site in
+http://localhost:8000 and will automatically rebuild the project when it
+detects modifications in one of the ``content``, ``static`` and ``templates``
+directories.
+
+.. code-block:: sh
+
+    $ blag serve
+
