There's a popular maxim that "a product is as good as its documentation". This holds true as much for software as it does for physical products.
As a small, indie developer who doesn't specialize in front-end design, I often hire a freelancer to build my product website—which, of course, usually includes a documentation section.
A documentation section can take quite a bit of time and money to build, even for a simple product, so it would be nice not to have to reinvent the wheel for every site. Fortunately, there is a way.
MkDocs is a free, static site generator geared towards building project documentation. It can be used to generate a stand-alone site, or just a documentation section of a larger site.
Because MkDocs produces static files, your documentation is light-weight and easy to host—using free services such as GitHub Pages and Read The Docs—or of course on your own server.
In this article, I'll introduce MkDocs, showing you how to install it, build documentation with it and finally host the generated documentation on a web server.
MkDocs is written in Python. The documentation source files are written in Markdown, and configured with a single YAML configuration file.
To build documentation with MkDocs, you need to have it installed locally in your computer. So let's next look at how to install it.
Installing Python and MkDocs
Static site generators like Jekyll (used mainly for blogging, and built on Ruby) and MkDocs do require some command-line chops, so be warned. However, to those not used to working with the command line, I encourage you to read on and give it a try, as it's not as bad as it looks!
Installing Python and pip
To install MkDocs, you need to have Python and pip (a Python package manager) installed in your computer. They may already be installed on your computer. If you have Python 3.4 or later installed, you probably have
pip installed. (See the Python installation guide for full instructions.)
To install Python on a Linux distribution such as Ubuntu, see this stackoverflow thread or do a Google search for your distribution.
For Windows, download your preferred version installer and run the file to install Python.
Alternatively, if you have the Chocolatey package manager installed in your machine, run
choco install python.
To verify that your Python distribution has
pip installed, run the
pip --version command. Otherwise, run
python get-pip.py or
choco install pip via
Chocolatey to get it installed.
Now that Python and pip are installed, run
pip install mkdocs to install MkDocs.
To confirm everything is fine, run
mkdocs help to give
mkdocs command a try.
If you are on Windows and the
mkdocs command isn't alive, be sure to add
Path environmental variable.
Building the Documentation
Now that you have Python and MkDocs set up, you can get on with your actual documentation.
Firstly, create a project for the documentation (let's call it
sp-doc) and navigate to the created folder:
$ mkdocs new sp-doc $ cd sp-doc
The generated project folder will contain a
docs folder—where the Markdown files for the documentation will be stored—and the configuration file
Here is the directory structure:
|-- docs # MD doc pages |-- index.md |-- mkdocs.yml # config file
Add the following bare-minimum configuration to
site_name: SitePoint Documentation site_description: Description of the documentation theme: readthedocs pages: - ['index.md', 'Index']
MkDocs ships with a number of themes—such as "MkDocs", "Read the Docs" and "Bootstrap". Say you intend to use the default theme. In that case, simply replace
mkdocs in the code above.
pages config is used to determine the set of pages that should be built for the documentation and the navigation menu.
Markdown files added to
pages must be relative to the
docs folder. For example, if you created a new folder called
config inside the
docs directory and added a
setup.md file in it, here's how you would add it to
pages in the
mkdocs.yml file configuration:
site_name: SitePoint Documentation site_description: Description of the description theme: readthedocs pages: - ['index.md', 'Index'] - ['start.md', 'Get Started'] - ['config/setup.md', 'Configuration', 'Setup'] - ['config/debug.md', 'Configuration', 'Debug']
This creates some new pages that appear automatically in our documentation menu. Firstly, there's a
start.md page, with the title "Get Started".
We've also added a new section to the documentation menu called "Configuration", under which there's a link to new Setup and Debug pages.
MkDocs includes a built-in web server, so you can preview your documentation locally as you work on it.
To start the web server, ensure you are in the directory where
mkdocs.yml config file resides, and then run the
mkdocs serve command.
http://127.0.0.1:8000 in your browser to view the documentation:
If you're satisfied with what you've created, run
mkdocs build to generate the static files for the documentation which will be saved to
You can copy the static files and host them on a web server of your choosing to take the documentation live.
Firstly, create a GitHub (or Bitbucket) repository to store the files.
Run the following commands to deploy to GitHub where
https://github.com/Collizo4sky/sitepoint_mkdocs is my own MkDocs repo:
$ git init $ git remote add origin https://github.com/Collizo4sky/sitepoint_mkdocs.git $ git add -A $ git commit -a -m 'the genesis' git push --set-upstream origin master
Let's now deploy our documentation files to Read the Docs, a free documentation service.
Read the Docs
Firstly, create an account if you don't have one and log in.
Import a Project button or click the
Add project menu item.
You can choose to connect your GitHub or Bitbucket account to Read the Docs to import your entire project. Instead, we'll go with the manual importation, by clicking the
Manually Import Project button.
Fill the form as shown in the image below:
On successfully importing the docs from GitHub, you'll be redirected to project page:
You can view our generated documentation at http://sitepoint-doc.readthedocs.org/en/latest/.
If you want the documentation on a subdomain, point a CNAME record in your DNS to the subdomain for your project.
For example, to make the documentation available on
docs.sitepoint.com, create a CNAME record pointing to
Now let's look at how to host our documentation on GitHub Pages, another free hosting service.
Ensure you are on the working branch of the git repository—which is the
master branch in our case.
Run the command
mkdocs gh-deploy --clean
Behind the scenes, this command will build your docs and commit them to the
gh-pages branch and then push the branch to GitHub.
Here is a demo of our SitePoint docs on GitHub Pages.
Any hosting provider that can serve static files can be used to serve documentation generated by MkDocs. The following guidelines should provide some general assistance.
When you build your site using the
mkdocs build command, all of the files are written to the directory assigned to the
site_dir configuration option (defaults to "site") in your
mkdocs.yaml config file.
Simply copy the contents of that directory to the root directory of your hosting provider's server and you are done. Or, if your docs will just be a subsection of your site, move the files to a designated subfolder.
Have you used MkDocs before? If not, would you consider using it? How do you currently deal with serving documentation to your users? I'd love to hear your feedback or answer any questions you might have.
