 ## Features
 
-![treeview](images/treeview-screenshot.png)
+![Entity Framework Migrations](images/treeview-screenshot.png)
 
-- List dbContexts for all projects within a solution
+- List migrations by [DbContext](https://learn.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.dbcontext)
 - Add/remove/run/undo migrations
+- Export [DbContext](https://learn.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.dbcontext) as SQL script
 
 ## Requirements
 
 - [dotnet sdk](https://dotnet.microsoft.com/download)
 - [efcore tools](https://learn.microsoft.com/en-us/ef/core/cli/dotnet)
-- A solution (`.sln`) file with projects
 - [Microsoft.EntityFrameworkCore.Design](https://www.nuget.org/packages/Microsoft.EntityFrameworkCore.Design) must be installed in one of the projects
 
 ## Extension Settings
 
 This extension contributes the following settings:
 
-- `entityframework.env`: Custom environment vars, for example:
-  ```json
-  {
-    "entityframework.env": {
-      "ASPNETCORE_ENVIRONMENT": "LocalDev",
-      "TenantId": "12345"
-    }
-  }
-  ```
 - `entityframework.commands`: Custom commands, for example:
-
   ```json

 ## Performance
 
-The EF tools execute application code at design time to get information about the project, thus performance can be slow on large projects.
