Introduction to YAML

# Popular tools that use YAML

YAML is a popular format for storing the following information: 
- Configuration files (server configs, application configs, etc.) 
- Arbitrary file formats (video games, music files, art files) 
- Data serialization (XML, JSON)  
- Documentation (technical documentation, API docs) 
- Markup formats (blog posts, forum posts) 

Below are some of the popular tools that use the YAML data format. 


### Travis CI

Travis CI is a hosted continuous integration service used to build and test software projects hosted at GitHub and Bitbucket. 

Travis CI uses a YAML file named _.travis.yml_ to store its configuration in your repository.
The concepts covered in this course are very important as your project will only build with Travis CI if it contains a valid configuration.

### Azure DevOps

A service to continuously build, test, and deploy to any platform and cloud. You define pipelines, which are stages of your CI/CD process, using YAML. 

Azure DevOps also provides other options like a visual designer for defining build and release pipelines. However, using YAML provides you additional flexibility as you can manage these pipelines like any other source file and version control it.
