+# Gilded Rose starting position in Csharp Core
+
+## Build the project
+
+Use your normal build tools. 
+
+## Run the TextTest fixture from the Command-Line
+
+For e.g. 10 days:
+
+```
+GildedRoseTests/bin/Debug/net7.0/GildedRoseTests 10
+```
+
+You should make sure the command shown above works when you execute it in a terminal before trying to use TextTest (see below). If your tooling has placed the executable somewhere else, you will need to adjust the path above.
+
+
+## Run the TextTest approval test that comes with this project
+
+There are instructions in the [TextTest Readme](../texttests/README.md) for setting up TextTest. You will need to specify the GildedRoseTests executable and interpreter in [config.gr](../texttests/config.gr). Uncomment this line:
+
+    executable:${TEXTTEST_HOME}/csharpcore/GildedRoseTests/bin/Debug/net7.0/GildedRoseTests
+
