+## Run the Text Fixture from Command-Line
+
+```
+./gradlew -q text
+```
+
+### Specify Number of Days
+
+For e.g. 10 days:
+
+```
+./gradlew run --args 10
+```
+
+You should make sure the gradle commands shown above work when you execute them in a terminal before trying to use TextTest (see below).
+
+
+## Run the TextTest approval test that comes with this project
+
+There are instructions in the [TextTest Readme](../texttests/README.md) for setting up TextTest. What's unusual for the Java version is there are two executables listed in [config.gr](../texttests/config.gr) for Java. One uses Gradle wrapped in a python script, the other relies on your CLASSPATH being set correctly in [environment.gr](../texttests/environment.gr).
