jekyll-intro

This how-to will guide you on how to setup a jekyll blog from scratch, hosted on Github Pages.

Gem installation

You will need a fresh ruby installation. If you don't, follow lewagon/setup

First, make sure you have jekyll installed with:

$ gem install jekyll

Repo initialization

We will create a site served at http://<your_github_username>.github.io and hosted on Github at <your_github_username>.github.io. In the previous terms, just remplace <your_github_username> with your own GitHub username, obviously.

$ cd ~/code/<your_github_username>
$ jekyll new <your_github_username>.github.io
$ cd <your_github_username>.github.io
$ git init
$ git add .
$ git commit -m "Jekyll blog generated"

Serve the blog locally

You can preview your blog articles locally. Open a new terminal tab, and run, in the root folder of your blog:

$ jekyll serve --watch

It will run forever, that's why we opened a new terminal tab. Then you can your browser, and go to the following URL:

http://0.0.0.0:4000

Great, this is your new blog! Time to write a new article.

Create a new article

Your articles live in the _posts folder of your jekyll project. To create a new article, you need to create a new file in this folder, with a filename strictly following the convention:

YYYY-MM-DD-the-blog-article.markdown

Where YYYY-MM-DD is the date of the date, and the-blog-article will be the URL where the article will be served:

http://0.0.0.0:4000/the-blog-article.html

Open this file in Sublime Text, and make sure the 4 first lines follow the following convention:

---
layout: post
title: "The Blog Article"
---

Then you can save your file, go to your browser and refresh your blog root page (listing all your articles). You should see a link to your new article. Click on it, you should see a blank article. Time to add some content with Sublime Text to posts/YYYY-MM-DD-the-blog-article.markdown!

Publish your blog on the Internet

You need to create a new GitHub repository. Go to github.com/new, and create repository named <your_github_username>.github.io. The name is very important. Once created, you will get instructions to add this remote to your local git repository (the two command specified at the bottom).

To publish your article, it's just a push:

$ git push origin master

Using your own domain

You will have to create a CNAME file. Here is a great guide.

Adding static pages

Suppose you want to have an "About" page or a "Resume" page. These are not really blog articles. And you want to have a special URL:

/about.html

Just create a file at the root of your jekyll project:

$ touch about.html

And then, inside this file, don't forget the head:

---
layout: default
title: About me
---

Note that the layout in this case is default, not post. They are related to what you can find in the _layouts folder!

/about

You can drop the .html suffix in your URL, in that case you need a folder:

$ mkdir about
$ touch about/index.html

Adding images

The Markdown syntax to add an image is:

![Alt text](/path/to/img.jpg)

You should create an images folder to put your images in:

$ mkdir images

This way, if you have an image me.jpg in your images folder, you can put it in your article with the following:

![Me](/images/me.jpg)

I want a contact form!

You can use Wufoo or Brace forms, I wrote an article about it.

I don't like the default look & feel!

Well, you can tweak the layout, or the CSS. You can also find some inspiration on jekyllthemes.org

I want to put comments on my blog!

Use Disqus!

Power stuff

In this section, I will explained stuff that happen automagically with Github Pages.

Build

Suppose you want to host your Jekyll site old-school, on your own server. You will need to upload the site to a FTP server. In that case, you need to build locally the site, and push this compiled version to the FTP. By default, it is built in the _site folder. You can read the doc

Liquid

Jekyll is using Liquid, a templating language created by Shopify. That's what you see if you wander in the _layouts folder. It gives you helpers, for loops and if conditions. You can read the great guide Liquid for Designers if you want to build your own template.

Data

You can store data in your repo, and view it as a static database. It can be useful if you want to create a page listing all your startup employees. Putting the employees in a yaml file and using a liquid {% for %} loop will help you create a greate page!
