Hackercouch is a platform that offers "hospitality for hackers." The idea behind it is to provide a way for hackers to find accommodations while traveling by leveraging the power of the open-source community. The process is simple: fork the hackercouch GitHub repository, add your own markdown file with your information, submit a pull request, and wait for the build to pass. Once approved, your information will be available on the hackercouch.com website for other hackers to see.
Jekyll is a static site generator written in Ruby that allows you to create simple, fast, and secure websites without the need for a database.
