Jekyll & GitHub Pages Content Management Cheat Sheet

Setting Up Your Environment

On Fedora/Red Hat Systems

# Install Ruby and development tools
sudo dnf install ruby ruby-devel openssl-devel @development-tools

# Install Bundler
gem install bundler

# Clone your repository
git clone https://github.com/[username]/[repository].git
cd [repository]

# Install dependencies
bundle install

On Immutable Linux Systems (Silverblue, Kinoite, etc.)

Method 1: Using Toolbox

# Create a toolbox for Jekyll development
toolbox create jekyll-tools
toolbox enter jekyll-tools

# Install required packages inside toolbox
sudo dnf install ruby ruby-devel openssl-devel @development-tools

# Install Bundler
gem install bundler

Method 2: Using Homebrew

# Install Homebrew (if not already installed)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
echo 'eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"' >> ~/.bashrc
source ~/.bashrc

# Install Ruby with Homebrew
brew install ruby

# Add Ruby to your PATH
echo 'export PATH="$(brew --prefix ruby)/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

# Install Bundler
gem install bundler

After either method, clone the repository and install dependencies:

# Clone the repository
git clone https://github.com/[username]/[repository].git
cd [repository]

# Install dependencies
bundle install

Creating New Content

Creating a New Blog Post

Create a new file in the _posts directory

# File must be named: YYYY-MM-DD-title.md
# Example: 2025-03-15-setting-up-jellyfin.md

Add front matter at the top of the file

---
layout: default
title: "Your Post Title"
date: 2025-03-15 10:30:00 -0500
categories: linux tutorials
---

Add your content below the front matter

Write your post content here using Markdown.

## Subheading

- List item 1
- List item 2

[Link text](https://example.com)

Creating a New Documentation Page

Create a new file in the docs directory
```
# Example: docs/new-guide.md
```

Add front matter

---
layout: default
title: "New Guide Title"
permalink: /docs/new-guide/
---

Add your content below the front matter

Updating Existing Content

Find the file to edit

# Posts are in _posts directory
# Documentation pages are in docs directory

Make your changes to the file

Test your changes locally

bundle exec jekyll serve
# Visit http://localhost:4000 in your browser

Publishing Your Changes

Add your changes to git
```
git add .
```

Commit your changes with a descriptive message

git commit -m "Add new guide about Jellyfin installation"

Push your changes to GitHub
```
git push origin main
```
Wait for your site to rebuild GitHub Pages will automatically rebuild your site (usually takes 1-5 minutes)

Common Front Matter Options

---
layout: default       # The layout template to use
title: "Page Title"   # The title of the page
permalink: /custom-url/ # Custom URL for the page
date: 2025-03-15      # Publication date (for posts)
categories: category1 category2 # Categories (for posts)
tags: tag1 tag2       # Tags (for posts)
published: true       # Set to false to hide a post/page
excerpt: "Summary text shown in feed" # Custom excerpt
---

Adding Images

Place image files in the assets/images directory

Reference images in your Markdown

![Alt text](/assets/images/my-image.jpg)

Creating Special Content Elements

Frustration Meter

<div class="frustration-meter">
    <div class="frustration-label">Frustration Level:</div>
    <div class="frustration-level">
        <div class="frustration-fill frustration-medium"></div>
    </div>
</div>

Tip Box

<div class="tip-box">
    <strong>Pro Tip:</strong> This is a helpful tip for users.
</div>

Reality Check

<div class="reality-check">
    <strong>Reality Check:</strong> Important warning or limitation to be aware of.
</div>

Working with RSS Feeds

Your site is configured to automatically generate an RSS feed at /feed.xml. This happens whenever you build the site or push to GitHub.

To customize RSS settings, edit your _config.yml:

feed:
  title: Please Don't Make Me Install Linux
  description: A guide for the reluctant, the confused, and those looking for practical solutions.
  path: feed.xml

Helpful Commands

# Start local server
bundle exec jekyll serve

# Build site without serving
bundle exec jekyll build

# Start server with draft posts visible
bundle exec jekyll serve --drafts

# See list of installed plugins
bundle info --bundled

# Update all dependencies
bundle update

# Check for outdated dependencies
bundle outdated

Troubleshooting Common Issues

Ruby Version Issues

If you encounter Ruby version errors, check your Ruby version:

ruby -v

For Fedora/RHEL systems, you might need to use dnf to install a specific version:

sudo dnf install ruby-2.7.0

Jekyll Build Errors

If Jekyll fails to build, check:

YAML syntax in front matter (indentation matters)
Liquid template syntax errors
Missing dependencies in the Gemfile

Permissions Issues

On Fedora/RHEL systems, you might need to adjust permissions:

# Fix gem installation permissions
mkdir -p ~/.gem/ruby
echo 'GEM_HOME=$HOME/.gem/ruby' >> ~/.bashrc
echo 'PATH=$HOME/.gem/ruby/bin:$PATH' >> ~/.bashrc
source ~/.bashrc
