Well, to ease down your baggage, Katacoda is here!

Let us begin by understanding the concept of Katacoda!

What is Katacoda?

Quoting the Katacoda website,

Katacoda’s aim is to remove the barriers to new technologies and skills.

Katacoda is a platform that is used to build live interactive demo and training environments. Therefore, in this current COVID-19 pandemic situation worldwide, it is becoming highly popular amongst the students, tech professionals, and many more. The catch here is that you do not require to install all the components associated with it.

In the case of the students, Katacoda helps to provide privacy to the students. How? Well, every student gets access to the new environment as well as isolation from one another. That further helps to explore the skills and the student can also question without any hesitation.

Therefore, you get a customized e-learning platform to perform best practices through the latest technologies and suggested workflows.

  • Whenever the users start the tutorial, this is the welcome screen.
  • & During the setup, you decide the number of steps for your tutorial. These files are created as a result of that.
  • Once the tutorial is over, this is the final screen.

When you are satisfied with all the changes that you have made, commit and push them to GitHub in the following manner:

git add .
git commit -m "My first Katacoda scenario"
git push origin main

And you’re done! Furthermore, to add the content to your scenarios, perform this simple step.

As you have created your first project, now is the time to add some content to it.

Edit your .md files and add the content in Markdown format.

There is another advantage. The Markdown is rendered on the left. Whereas, the users can execute commands on the right side, on the same screen. It offers you great ease while you are working. Take a look.
