 ### Declare SwiftPM dependency with nightly build
 
 1. Download and install the latest Trunk Development [toolchain](https://swift.org/download/#snapshots).
 
 2. Define the `TOOLCHAINS` environment variable as below to have the `swift` command point inside the toolchain:
-
-```
-$ export TOOLCHAINS=swift
-```
+    ```bash
+    $ export TOOLCHAINS=swift

 3. To make sure everything is set up correctly, check the result of `xcrun --find swift`. It should point inside the OSS toolchain.

 If you also want to run tests locally, read the section below as testing has additional requirements.
 
 ### Local Testing
+
 SwiftSyntax uses some test utilities that need to be built as part of the Swift compiler project. To build the most recent version of SwiftSyntax and test it, follow the steps in [swift/README.md](https://github.com/apple/swift/blob/main/README.md) and pass `--llbuild --swiftpm --swiftsyntax` to the build script invocation to build SwiftSyntax and all its dependencies using the current trunk (`main`) compiler.
 
 SwiftSyntax can then be tested using the build script in `apple/swift` by running
-```
+
+```bash
 swift/utils/build-script --swiftsyntax --swiftpm --llbuild -t --skip-test-cmark --skip-test-swift --skip-test-llbuild --skip-test-swiftpm
 ```
+
 This command will build SwiftSyntax and all its dependencies, tell the build script to run tests, but skip all tests but the SwiftSyntax tests.
 
 Note that it is not currently supported by SwiftSyntax while building the Swift compiler using Xcode.

-Declarative and type-safe wrapper around SwiftSyntax.
+**Swift Syntax Builder** is an open-source package for generating Swift code in a declarative way.
 
-## Example Usage
+> Note: SwiftSyntaxBuilder is still in development, and the API is not guaranteed to
+> be stable. It's subject to change without warning.
 
 ```swift
-let sourceFile = SourceFile {
-  Import("SwiftSyntax")
+import SwiftSyntaxParser
 
-  Struct("ExampleStruct") {
-    Let("syntax", of: "Syntax")
-  }
+let source = SourceFile {

+
+## Usage
+
+### Declare SwiftPM dependency with release tag
+
+Add this repository to the `Package.swift` manifest of your project:
+
+```swift
+// swift-tools-version:5.3
+import PackageDescription
+
+let package = Package(
+  name: "MyTool",
+  dependencies: [
+    .package(name: "SwiftSyntax", url: "https://github.com/apple/swift-syntax.git", .exact("<#Specify Release tag#>")),
+  ],
+  targets: [
+    .target(name: "MyTool", dependencies: ["SwiftSyntaxBuilder"]),
+  ]
+)
+```
+
+Replace `<#Specify Release tag#>` by the version of SwiftSyntaxBuilder that you want to use. See this following [table](https://github.com/apple/swift-syntax#declare-swiftpm-dependency-with-release-tag) for mapping details.
+
+Then, import `SwiftSyntaxBuilder` in your Swift code.
+
+Note that SwiftSyntaxBuilder has limited support for pretty-printing code. We generally suggest running a formatter like [swift-format](https://github.com/apple/swift-format) on the generated code.
+
+### Reporting Issues
+
+If you should hit any issues while using SwiftSyntaxBuilder, we appreciate bug reports on [bugs.swift.org](https://bugs.swift.org) in the [SwiftSyntax component](https://bugs.swift.org/issues/?jql=component%20%3D%20SwiftSyntax).
