-# Microsoft SQL Server Database Projects for Azure Data Studio and VS Code
+# SQL Database Projects for Azure Data Studio and VS Code
 
 ## Overview
 
-Microsoft SQL Server Database Projects for Azure Data Studio and VS Code provides a way to design, edit, and publish schemas for SQL databases from a source controlled project.
+SQL Database Projects for Azure Data Studio and VS Code provides a way to design, edit, and publish schemas for SQL databases from a source controlled project.  For a complete development workflow, build and deploy your database projects in CI/CD pipelines, such as [GitHub Actions](https://github.com/azure/sql-action) or Azure DevOps.
 
-### VS Code
+Learn more about the SQL Database Projects extension in the documentation: https://aka.ms/azuredatastudio-sqlprojects
 
-This extension is bundled into the `SQL Server (MSSQL)` extension for VS Code and will be installed automatically when that extension is updated or installed.
+## Features
 
-### Azure Data Studio
+- Develop database objects using T-SQL
+- Store the database schema in source control
+- Validate object relationships with project build
+- Publish the database objects to a SQL Server or Azure SQL instance
+- Publish the database objects to a local development container
+- Update the database project from a database
 
-This extension is provided as a separate extension in the marketplace.
+### Preview Features
+
+- Microsoft.Build.Sql SDK-style projects
+- Generate SQL projects from OpenAPI/Swagger specs
 
 
-Please report issues and feature requests [here.](https://github.com/microsoft/azuredatastudio/issues)
+![AdventureWorks SQL project](images/readme-sqlproj.png)
+
 
 ## Getting Started with Database Projects
 
 * Create a new database project by going to the `Database Projects` view or by searching `Database Projects: New` in the command palette.
 * Existing database projects can be opened by going to the `Database Projects` view or by searching `Database Projects: Open existing` in the command palette.
-* Start from an existing database by using the `Create Project from Database` from the command palette or database context menu.
+* Start from an existing database by using `Create Project from Database` from the command palette or database context menu.
 * Start from an OpenAPI/Swagger spec by using the `Generate SQL Project from OpenAPI/Swagger spec` command (Preview).
 
+## Settings
+
+### General Settings
+- `sqlDatabaseProjects.dotnetSDK Location`: The path to the folder containing the `dotnet` folder for the .NET SDK. If not set, the extension will attempt to find the .NET SDK on the system.
+- `sqlDatabaseProjects.microsoftBuildSqlVersion`: Version of Microsoft.Build.Sql binaries used when building SQL projects that are not SDK-style SQL projects. If not set, the extension will use Microsoft.Build.Sql 0.1.9-preview.
+- `sqlDatabaseProjects.netCoreDoNotAsk`: When true, no longer prompts to install .NET SDK when a supported installation is not found.
+- `sqlDatabaseProjects.collapseProjectNodes`: Option to set the default state of the project nodes in the database projects view to collapsed. If not set, the extension will default to expanded.
+
+### AutoRest Settings (preview)
+
+- `sqlDatabaseProjects.nodejsDoNotAsk`: When true, no longer prompts to install Node.js when a supported installation is not found.
+- `sqlDatabaseProjects.autorestSqlVersion`: Version of AutoRest.sql to use for generating SQL projects from OpenAPI/Swagger specs. If not set, the extension will use the latest version.
