 # Buf for Visual Studio Code
 
-## Installation
+The [VS Code Buf extension](https://marketplace.visualstudio.com/items?itemName=bufbuild.vscode-buf) provides rich support for [Protocol Buffers](https://protobuf.dev/) using the [Buf](https://buf.build/) development environment.
 
-Install via the Visual Studio Code extension browser or see
-[the extension page](https://marketplace.visualstudio.com/items?itemName=bufbuild.vscode-buf)
-for detailed installation instructions.
-
-## Features
+## Requirements
 
-- Lints your protobuf files using `buf lint`. It checks your currently opened file
-  whenever you save it.
+* Visual Studio Code
+* A [Buf](https://buf.build/) configuration environment.
 
-  ![Lint errors](./lint_errors.png)
+## Getting Started
 
-- Formats your protobuf files using `buf format`.
+The Buf CLI is the ultimate tool for modern, fast, and efficient Protobuf API management. Getting started is simple!
 
-- Provides syntax highlighting for `.proto` files.
+1. Install the [VS Code Buf extension](https://marketplace.visualstudio.com/items?itemName=bufbuild.vscode-buf).
+2. Create a [buf.yaml](https://buf.build/docs/cli/#default-configuration) in the root of your workspace.
+3. Open any Protobuf file to automatically activate the extension. A Buf status bar appears in the bottom right corner of the window.
+4. The extension depends on the [Buf CLI](https://buf.build/docs/cli/). If a Buf binary is not found in your path, the extension will attempt to install the latest release from Github.
 
-## Requirements
+## Features
 
-- [buf](https://docs.buf.build/installation)
+- **Code navigation** - Jump to or peek at a symbol's declaration.
+- **Syntax highlighting** - Protobuf specific color and styling of code.
