 Before we begin larger updates to the site with the help of Copilot, we want to ensure Copilot has a good understanding of how we're building our application. As a result, we're going to add a Copilot instructions file to the repository.
 
-Copilot instructions is a markdown file is placed in your **.github** folder. It becomes part of your project, and in turn is available to all contributors to your codebase. You can use this file to indicate various coding standards you wish to follow, the technologies your project uses, or anything else important for Copilot Chat to understand when generating suggestions.

 > The *copilot-instructions.md* file is included in **every** call to GitHub Copilot Chat, and will be part of the context sent to Copilot. Because there is always a limited set of tokens an LLM can operate on, a large Copilot instructions file can obscure relevant information. As such, you should limit your Copilot instructions file to project-wide information, providing an overview of what you're building and how you're building it. If you need to provide more specific information for particular tasks, you can create [prompt files](https://docs.github.com/copilot/customizing-copilot/adding-repository-custom-instructions-for-github-copilot?tool=vscode#about-prompt-files).

 # Part 05: Implementing Features with Copilot Agent
 
-Previously we utilized Copilot chat, which is great for working with an individual file or asking questions about our code. However, many updates necessitate changes to multiple files throughout a codebase. Even a seemingly basic change to a webpage likely requires updating HTML, CSS, Razor, and C# files. Copilot Agent allows you to modify multiple files at once across your project, self heals, and can run commands if granted permission like installing NuGet packages.

 With Copilot Agent, you will add the files which need to be updated to the context. Once you provide the prompt, Copilot Agent will begin the updates across all files in the context. It also has the ability to create new files or add files to the context as it deems appropriate.
