+## Running a local environment for development 
+If you do not have the proper Postgres database running locally, you can instead use the default embedded database:
+1. Remove the Postgres-related connection strings from TagzApp.Blazor\appsettings.Development.json
+2. Run from the command line: `dotnet watch --project .\src\TagzApp.Blazor\`.
+   The site should spin up and open the First Start Configuration page.
+3. Choose Sqlite and submit. After a short delay, The home page should show.
