This course is designed to teach students Haskell from zero to everything needed to work with Marlowe and Plutus. The course itself doesn't contain content specific to Marlowe or Plutus. So, if you want to use it to learn Haskell for other purposes, you can! π
For a more detailed explanation, keep reading or watch the introduction video:
In the outline below, there are clear stopping points (for both Marlowe and Plutus) where we deem you to know enough Haskell to effectively use the technology.
To go through the interactive lessons, go to your chosen lesson's outline inside "What we'll cover" and click on the button that looks like the one below. If the page loads with a "500: Internal Server Error" just refresh it, and it should be fine. At the top, you will see a console that displays the progress of preparing your interactive lesson. During this time, you can scroll down and look at the lesson, that is displayed non-interactively.
And to see the video, click on the button that looks like this:
- Clone this repository.
- Create a GitPod account.
- Click this button to create a remote dev environment:
- Select the
Homework/HomeworkXX
folder with the homework you want to complete. - Follow the instructions inside the app/Main.hs file.
- Check the solutions in the "solutions" branch!
