Setting Up Github Pages site with Jekyll Tutorial

This tutorial is cross-posted on my github

Jekyll is a static site generator. With Jekyll, you can write your pages in markdown from which it will build your html pages based on the layout settings. For example, if the markdown file you're writing is project1.markdown, Jekyll will build the project1.html file for you. There's no need to tweak the html, css, or whatever it is for the layout unless you want to do some customization. The Jekyll theme you're using alone already allowed some customization (think of working with Bootstrap) and you can easily change them using the provided field.

Steps

Install Ruby and Jekyll

Follow the instruction from this page for Windows.

Prepare Your Project Folder

We will prepare and test out pages locally first. These first steps are modified from this.

Make the new project folder. Choose any names, e.g. myblog, because this won't be the name for your repository, as your default github page is username.github.io.
Open command prompt and navigate to project folder.
Choose the directory where you are going to publish your site.
- If you choose to publish your site from the root of the repository, /, your github pages will appear directly on the root, e.g. username.github.io. If you choose this, you don't need to make any new directory
- If you choose to publish your site from a specific folder of the repository, e.g. /docs, your github pages will appear on that page, e.g. username.github.io/docs. If you choose this, make a new directory, then navigate to that folder.
```
mkdir docs
# Creates a new folder called docs
cd docs
```
Create a new Jekyll site in the current directory
```
jekyll new
```
Install your theme, e.g. "Just-the-Docs" theme. The default theme for new Jekyll site is "minima".
```
gem install just-the-docs
```
add it to your Jekyll site’s Gemfile
```
gem "just-the-docs"
```
Add Just the Docs theme to your Jekyll site’s _config.yml
```
theme: "just-the-docs"
```
Run your local Jekyll server then open your local site on browser: http://localhost:4000
```
bundle exec jekyll serve
```

Make Changes to Your Pages

In this step, you can try adding some pages, customization, and test them locally. When you're changing the _config.yml file, the update will not be applied unless you restart the server and run this line again: bundle exec jekyll serve

Always check the theme documentation to write your pages and setting them up! When you want to customize your theme CSS, check the theme documentation.

After you've completed setting up your pages and your site is running okay locally, proceed to the next step.

Push Existing Project to Github

Create a new repository on Github. Type a name for your repository. If you're creating a user site, your repository must be named <yourusername>.github.io. Do not add any files because we're going to push the files from local.
Unless you're already working in the root of your project folder, navigate to the root. Initialize git repository in the current directory (must be the root folder).
```
git init
```
Edit the Gemfile that Jekyll created.
- Add "#" to the beginning of the line that starts with gem "jekyll" to comment out this line.
- Add the github-pages gem by editing the line starting with # gem "github-pages". Change this line to:
```
gem "github-pages", "~> GITHUB-PAGES-VERSION", group: :jekyll_plugins
```
  Replace GITHUB-PAGES-VERSION with the latest supported version of the github-pages gem. Check the version here: "Dependency versions".
- Save and close the Gemfile
If you're using Jekyll theme other than the supported themes, edit your _config.yml file. For example, for "Just-the-Docs" theme, change this line: theme: "just-the-docs to this:
```
remote_theme: pmarsceill/just-the-docs
```
For another theme, check the theme documentation.
From the command line, run bundle update

Add your GitHub repository as a remote

git remote add origin https://github.com/<username>/<username>.github.io.git

Then add, commit, and push your files to the remote

git add .
git commit -m "initial commit"
git remote -v
git push origin master

Open your github pages. If there's something wrong, e.g. theme doesn't load, check your email! When there's something wrong, you will get a Page build failure or Page build waning email.

Use a Customized CSS

If you're using a customized CSS (e.g. changing or adding new styles) and run them locally, you usually edit the theme by editing a scss file in the directory of the theme. For example, for "Just-the-Docs" theme, your custom.scss file is in this directory:

C:\Ruby27-x64\lib\ruby\gems\2.7.0\gems\just-the-docs-0.3.3\_sass\custom\custom.scss

Check the path to the installed theme directory using this bundle info --path "THEME-NAME"

However, when you're running your page on Github Pages, you must make the directory and the file yourself in the folder where you will publish your site. The exact directory is different for each theme, e.g. for "Just-the-Docs", the directory for the new file is _sass/custom/custom.scss. You should follow your theme documentation when you add the contents of the new file. Example with Minima theme here.
