 ### Importance of using languages matrices with code scanning
 
 1. **Simplicity**: Using a language matrix with CodeQL simplifies your workflow by allowing you to manage multiple languages in a single workflow file. This eliminates the need for separate workflows for each language, making your code scanning process more streamlined and manageable.
-2. **Flexibility**: A language matrix provides flexibility as it allows you to easily add or remove languages from your workflow. This means you can quickly adapt your code scanning process to changes in your project's language usage.
+2. **Flexibility**: A language matrix provides flexibility, as it allows you to easily add or remove languages from your workflow. This means you can quickly adapt your code scanning process to changes in your project's language usage.
 3. **Consistency**: By using a language matrix, you ensure consistent code scanning across all languages used in your project. This helps maintain the quality and security of your codebase, regardless of the language it's written in.
 
 Remember, a well-configured CodeQL setup is key to maintaining a secure and reliable codebase.

-With the language matrix specified we can see the languages that we want to scan. One of those languages is a compiled language, and as such will not work correctly with how we have the workflow set up. We need to make sure that the autobuild step is included _and_ only runs when it is needed.

 Autobuild for CodeQL is a feature that automatically attempts to build any compiled languages in your repository. It works by detecting the build system in your repository and executing the appropriate commands to compile the code, enabling CodeQL to analyze the compiled language.
