Requirements

The 0x90skids website is build using [Jekyll]() a static web generator. Jekyll enables you to write site content in markdown and generate static web pages. It also enables you to run a simple local development server to live preview changes. See Editing Locally with Jekyll for installation instructions.

Jekyll Structure

• _chals: contains individual markdown ctf challenges, generated on the /ctf past
• _data: contains the links for the navivation bar
• _includes: contains the html code for items like headers, footers, navbar, ect
• _layouts: contains the html for page layouts like post pages, the home page, the ctf page, ect
• _posts: contains markdown files for blog posts (i.e ctf writeups)
• _sass: contains custom css files
• _site: contains the statically generated jekyll content
• _assets: contains css, favicons, images, ect
• nodes_modules: contains bootstrap data

Editting Locally with Jekyll

1) Clone the repository

git clone https://github.com/0x90skids/0x90skids.github2.io.git

2) cd into cloned directory

cd 0x90skids.github2.io

3) Install dependencies

Running the development server locally requires ruby and bundle.

On MacOS X these can be installed with brew :

brew install ruby 

On Ubuntu, this can be installed via apt :

sudo apt install ruby ruby-bundler ruby-dev

4) Install the required dependencies

bundle install 

5) Checkout the dev branch

git checkout dev 

6) Launch development server

jekyll serve 

You might have to start the development server with bundle exec

bundle exec jekyll serve

1) Make edits to the development branch. You can preview changes live by visiting http://127.0.0.1:4000

2) Any pull requests into the master branch will automatically trigger Netlify to build the site. Build status will be shown in the pull request, and can be seen with the Netlify build badge.

Creating a new post

1) Posts are held in the _posts directory

2) CTF writeups are held in the _posts/ctf directory

3) To create a new writeup, create a new markdown file in the writeup directory and add the necessary frontmatter content to the top

---
layout: 
title: 
date: 
modified:
description: 
tag:
  - ctf
  - writeup
image: 
---

4) Update the frontmatter variables with the necessary information and merge to master branch

Adding Challenges to the CTF

Markdown files in the _chals directory are statically generated into the custom /ctf page using the ctf html layout located in _layouts/ctf.html. In order to properly render these md files, a series of {{if}} .... {{else}} liquid tags in ctf.html are used to categoriese and display the challenges.

Because of these tags, it's very impoartant to fill out the appropriate frontmatter information on the md file.

How to add chals to the ctf page

1) Create a new challenge md file in the _chals directory

2) Edit the necessary frontmatter tags.
