It's a good starting point, the lessons were clear. The difficulty now begins with the specific api on which to apply the yaml writing

It is. I started working with an Industial DataOps solution that requires YAML files and I had to figure out the features and benefits by myself. This is making things clear.

Thank you so much! Now, I can read existing YAML files in any projects and write YAML files on my own.

The course has a lot to be improved: 1) Exercises should be included 2) tools he advises should be changed, the one he suggests are not anymore in use. 3) more details inside scalar and were this variables point. Is a YAML file an interface tool between cloud and execution programming? A lot of question has not been answer so it should be called a light introduction to YAML.

This course is well-organized. It seems like there are two points missing: 1, # using dollar($) sign before environmental variables 2, use double curly brackets around the placeholder, and this value gets replaced using template generator

This course is extremely easy to follow and suitable for newbies. But I think we need to practice directly on YAML testing tools to know what happens to be more effective. Thank you very much.

Very thorough introduction; outlines the lecture, then recaps, and I like that I've printed out the slides so I can just listen and can take a few notes here and there.

This is a pure YAML-specific course if you are new to YAML then this is the best place I must say to gain all information about YAML from beginner to advance. Thanks, Madan for such informative content.

Explanation and the documentation provided is very useful. Providing more examples with various scenarios would have been more helpful.

A very good and exhaustive course on YAML put together in an engaging way. Never knew that YAML has so many features. The author has broken them down very well to understand them in a simple way. The examples and tools used for demonstration and verification are quite useful in everyday life of a developer.

This is a very good course. It starts with the simple explanation of YAML files and then progresses through to more advanced applications of YAML files.

The course is good enough to understand the yaml syntax. However most of the examples are not from real life configs. IMHO would be nice to see the deeper explanation of simple syntax on various tools like docker, kubernetes, CI/CD tools etc. That would lead to better understanding of the existing files and how to implement the gained knowledge: e.g. more practical use cases for date, strings, other variables and why it can be useful. Bad practice is appreciated as well.
