How to Use the 'mkdocs' Command (with Examples)

MkDocs is an open-source static site generator geared towards project documentation. It’s designed to project documentation using Markdown and allows users to effortlessly turn a set of Markdown documents into a visually appealing static site. Users can build professional documentation sites with minimal effort, serve them locally to preview changes, and deploy them to platforms like GitHub Pages.

Use Case 1: Create a New MkDocs Project

Code:

mkdocs new project_name

Motivation:

Starting a new documentation project often requires a structured environment. Using this command to create a new MkDocs project provides you with a clean and organized file structure that can be expanded as your project grows. It’s an efficient way to set up the boilerplate of a documentation site, allowing you to focus on writing content rather than managing folder hierarchies or configurations.

Explanation:

• mkdocs: This is the base command that interacts with the MkDocs package.
• new: This subcommand tells MkDocs to create a new project. It initializes a new directory with a basic configuration file and some example pages.
• project_name: Replace this placeholder with your desired project name. It specifies the new directory where your project’s initial files will be established.

Example Output:

When you run this command, a new directory named project_name will be created, containing the following file structure:

project_name/
    mkdocs.yml
    docs/
        index.md

The mkdocs.yml file is the configuration file for your MkDocs project, while the docs/ directory is where you will store your Markdown documents.

Use Case 2: Serve the Project in the Current Directory

Code:

mkdocs serve

Motivation:

Previewing changes in real-time is crucial when developing documentation. The mkdocs serve command allows developers to see the impact of their changes instantly, thanks to the built-in development server. It updates the site view as you edit Markdown files, which greatly enhances workflow efficiency by removing the need to manually compile or refresh every time a change is made.

Explanation:

• mkdocs: This is the primary command for working with MkDocs.
• serve: This subcommand launches the development server. It renders your documentation site and serves it at a local address you can access via your web browser.

Example Output:

Running this command starts a local server (usually at http://127.0.0.1:8000/), where you can view and interact with your live documentation site. The terminal will continuously watch for changes and automatically refresh the webpage.

Use Case 3: Build the Documentation in the Current Directory

Code:

mkdocs build

Motivation:

Before deploying your documentation site, it’s essential to convert your Markdown files into a fully functioning static site. The mkdocs build command is designed to compile your project and generate the static files required for deployment. This process ensures that everything is correctly formatted and aligned with your configuration settings.

Explanation:

• mkdocs: This is the basic command for MkDocs operations.
• build: This subcommand compiles your project files and generates static HTML, CSS, and other assets. The output is placed into a directory named site/ by default, which is suitable for serving your documentation from a variety of platforms.

Example Output:

Executing this command results in the generation of a site/ directory within your project’s folder. This directory contains the built version of your documentation site, ready for deployment.

Use Case 4: Deploy the Documentation to GitHub Pages

Code:

mkdocs gh-deploy

Motivation:

Deploying your documentation to a live server is one of the final steps in sharing your project with the world. By using the mkdocs gh-deploy command, you can quickly publish your site to GitHub Pages, a platform that hosts static sites for free. This provides an easy and cost-effective method to share your documentation on a reliable platform that offers a seamless integration with your GitHub repository.

Explanation:

• mkdocs: The root command for interacting with MkDocs tools.
• gh-deploy: This subcommand automates the deployment process to GitHub Pages. It takes your built site and pushes it to the gh-pages branch of your GitHub repository. This branch is used by GitHub to serve your documentation as a live website.

Example Output:

When this command is executed, your documentation is uploaded to GitHub Pages. The command typically provides feedback in the terminal about the finished deployment, and once complete, your documentation will be accessible via https://<username>.github.io/<repository>/.

Conclusion:

MkDocs simplifies the process of creating, managing, and deploying project documentation. Each command within MkDocs serves a specific purpose, enabling a streamlined workflow from project creation through to deployment. Whether you’re crafting a new documentation project or preparing to share your work with others, MkDocs provides the necessary tools to make the process efficient and effective.
