+## Welcome to Challenge 19
+
+Welcome to the 19th Challenge 
+
+Today's challenge is unique. Today we will learn about code linting. A linter is defined as follows: 
+- Lint, or a linter, is a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs. 
+
+So in order to ensure proper codestyling and structure, there are checks run on pull requests to ensure the code is properly linted. We have also placed a code linter Github action which will keep a track whether your code is properly linted or not. 
+
+Task: 
+1. Create a new file inside your branch created in previous challenges ``your-username-details`` under the directory ``contributors/username``. The file needs to be a source code file written in your preferred programming language. The code can be anything you want: hello world program or your favorite program. 
+2. Commit the change and push it. 
+3. Check if your linting fails in side the Pull request: <img width="870" alt="image" src="https://user-images.githubusercontent.com/19529592/190969615-f3205b26-83eb-4b5f-b7a5-19567a575a9a.png"> <br> Then lint your code to ensure that this check passes inside your pull request.

+## Welcome to Challenge 20
+
+Welcome to the 20th Challenge 
+
+Today you will learn about project boards on GitHub
+
+### What are Github Project Boards?
+
+GitHub project boards helps you keep track of stuffs you're actively working on within your repository. You can say it's a project managemnet tool, or even a collaboration tool for teams. You create a project board with columns for your TODO or backlogs or even bugs, In progress activies and lastly a column for your finished tasks. You can sort of see it as a SCRUM board. To learn more [about project boards go through this link](https://help.github.com/en/github/managing-your-work-on-github/about-project-boards)
+
+## Tasks
+
+- Create a GitHub repository for any project you can think up
+- On a sheet of paper create a TODO list (or backlog) of features you want to have in you app
+- Create a project board with a `TODO` column, `In progress`, `Done`
+- Create a card for all the items you already wrote on the sheet of paper in the TODO column
+- Work on the features synchronously and move the card respectively for each in progress task to the `In progress` column
+- When you're done with the `In progress` task move the card to the `Done` column
+
+## How to submit your entry
+
+- Take a screenshot of your project board for when you moved an card from `In progress` to `Done`
+- Add you screenshot to the Github issue created in the previous challenges
