+# Gilded Rose starting position in C with CMocka
+
+Use CMake to build it. Run the target "sample_test" to run the sample unit test using the cmocka framework.
+
+## Run the TextTest fixture on the command line
+
+When you build this project this executable should be created:
+
+    c_cmocka/cmake-build-debug/main
+
+Execute it on the command line with an argument for the number of days:
+
+    c_cmocka/cmake-build-debug/main 10
+
+## 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 C executable in [config.gr](../texttests/config.gr). Uncomment this line to use it:
+
+    executable:${TEXTTEST_HOME}/c_cmocka/cmake-build-debug/main
