From Docs to Deploy: Your Complete Guide to Hosting MkDocs on GitHub Pages

Published on June 6, 2025 | 8 min read

Ever wanted to share your project documentation with the world but got stuck on the hosting part? You're not alone! Today, I'm going to walk you through exactly how to get your MkDocs documentation site live on GitHub Pages – and the best part? It's completely free.

Whether you're documenting an open-source project, creating internal team guides, or building a knowledge base, this guide will have you up and running in no time. Plus, I'll share some hard-learned lessons to help you avoid the common pitfalls I've encountered along the way.

Why MkDocs + GitHub Pages = 💛

Before we dive in, let me quickly explain why this combination is so powerful. MkDocs transforms your Markdown files into beautiful, searchable documentation sites. GitHub Pages gives you free, reliable hosting with automatic SSL certificates. Together, they create a workflow that's both developer-friendly and maintainable.

The cherry on top? You can set up automated deployments so your docs update automatically every time you push changes. No more manual uploads or forgotten updates!

What You'll Need Before We Start

Let's make sure you have everything ready. Don't worry – the requirements are pretty minimal:

  • A GitHub repository with your MkDocs project (or ready to create one)
  • Python 3.10 or higher – check with python3 --version
  • Git configured with your GitHub credentials
  • Basic familiarity with command line operations

If you're starting from scratch, you'll also want to have your documentation content ready in Markdown format. Even a simple index.md file will do for now!

Setting Up Your MkDocs Project

Getting Your Configuration Right

The foundation of any good MkDocs site is a solid mkdocs.yml configuration file. Here's what yours should look like:

site_name: Your Project Name
site_url: https://your-username.github.io/your-repo-name/
site_description: A brief description of your project
site_author: Your Name

theme:
  name: material  # I highly recommend the Material theme

nav:
  - Home: index.md
  - Getting Started: getting-started.md
  # Add your navigation structure here

Pro tip: That site_url field is crucial! It ensures all your internal links work correctly when deployed. I learned this the hard way when my first deployment had broken navigation throughout the entire site.

Creating a Clean Development Environment

I'm a big believer in virtual environments – they've saved me from dependency hell more times than I can count. Here's how to set one up:

# Create your virtual environment
python3 -m venv .venv

# Activate it (Linux/macOS)
source .venv/bin/activate

# On Windows
.venv\Scripts\activate

Now install MkDocs and the Material theme:

pip install mkdocs mkdocs-material

Want to level up your docs? These plugins are game-changers:

pip install mkdocs-awesome-pages-plugin mkdocs-git-revision-date-localized-plugin

Essential Project Files

Don't skip this part! A good .gitignore file will save you from accidentally committing build artifacts:

# MkDocs build output
/site/

# Python virtual environment
.venv/
venv/

# Python cache files
__pycache__/
*.py[cod]
*$py.class

# Development tools
.vscode/
.idea/
*.swp

# System files
.DS_Store
Thumbs.db

And always pin your dependencies:

pip freeze > requirements.txt

Trust me, future you will thank present you for this when you need to reproduce your exact setup.

Testing Locally (Don't Skip This!)

Before we deploy anything, let's make sure everything works locally. This is where the magic happens:

mkdocs serve

Open http://127.0.0.1:8000 in your browser, and you should see your documentation site in all its glory! The live reloading feature means any changes you make to your files will instantly appear in the browser.

If you just want to build the site without serving it:

mkdocs build

This creates a /site directory with all your compiled HTML, CSS, and JavaScript files.

Deploying to GitHub Pages: Two Paths to Success

Now for the moment of truth – getting your site live! I'll show you two methods, and honestly, both have their place.

Method 1: The Quick and Easy Way

MkDocs has a built-in deployment command that's perfect for personal projects:

mkdocs gh-deploy

That's it! This single command:

  • Builds your documentation
  • Creates or updates a gh-pages branch
  • Pushes everything to GitHub
  • Cleans up old files automatically

Want more control? Here are some advanced options:

# Clean deployment with a custom commit message
mkdocs gh-deploy --clean --message "Deploy documentation update {version}"

# Deploy from a different branch
mkdocs gh-deploy --remote-branch main

Method 2: GitHub Actions (My Preferred Approach)

For team projects or when you want automated deployments, GitHub Actions is the way to go. Create .github/workflows/docs.yml:

name: Deploy Documentation

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

permissions:
  contents: read
  pages: write
  id-token: write

jobs:
  build:
    runs-on: ubuntu-latest
    
    steps:
    - uses: actions/checkout@v4
      with:
        fetch-depth: 0
    
    - name: Setup Python
      uses: actions/setup-python@v4
      with:
        python-version: '3.11'
    
    - name: Install dependencies
      run: pip install -r requirements.txt
    
    - name: Build documentation
      run: mkdocs build
    
    - name: Upload artifact
      uses: actions/upload-pages-artifact@v2
      with:
        path: ./site
  
  deploy:
    needs: build
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    
    steps:
    - name: Deploy to GitHub Pages
      id: deployment
      uses: actions/deploy-pages@v2

This workflow automatically deploys your docs every time you push to the main branch. It's like having your own personal deployment assistant!

Configuring GitHub Pages

Head over to your repository settings and navigate to the Pages section. Here's what you need to do:

  1. Under Source, choose:
    • Deploy from a branch (select gh-pages) if using mkdocs gh-deploy
    • GitHub Actions if using the workflow method
  2. Click Save

That's it! GitHub will start building your site.

When Things Go Wrong (And They Sometimes Do)

Here are the most common issues I've encountered and how to fix them:

Site not updating after deployment?

  • Double-check your GitHub Pages settings
  • Verify your site_url matches your actual GitHub Pages URL
  • Try a hard refresh or incognito browser window

Build failures?

  • Run mkdocs build --strict locally to catch issues early
  • Check for broken internal links
  • Make sure all plugins are in your requirements.txt

Permission errors?

  • Confirm you have write access to the repository
  • For organization repos, ensure GitHub Actions are enabled

Pro Tips for Documentation Success

After deploying dozens of documentation sites, here are my top recommendations:

Keep it organized: Use a logical navigation structure in your mkdocs.yml. Your users will thank you for making information easy to find.

Optimize for performance: Compress images and consider using external CDNs for heavy resources. Fast sites keep readers engaged.

Automate everything: Set up branch protection rules and use pull request reviews for important changes. Your documentation is code too!

Test before you deploy: Always run mkdocs serve locally before pushing changes. It's much easier to catch issues on your machine than in production.

Wrapping Up

And there you have it! Your MkDocs documentation should now be live at https://your-username.github.io/your-repo-name/. Changes typically appear within 1-2 minutes of deployment.

The beauty of this setup is that it grows with your project. Start simple with the manual deployment method, then upgrade to GitHub Actions when your team grows or you need more automation.

Remember, great documentation is an iterative process. Start with the basics, gather feedback from your users, and continuously improve. Your future self (and your users) will appreciate the effort you put in today.

Happy documenting! 🚀
