 # rt-validation
 
 Containers to validate real-time (PREEMPT_RT) support in TorizonCore

+
+# Build containers (on target machine)
+
+For armhf:
+```
+docker build -t torizon/rt-validation-stress stress-tests
+docker build -t torizon/rt-validation-rt rt-tests
+```
+
+For arm64:
+```
+docker build --build-arg IMAGE_ARCH=linux/arm64 -t torizon/rt-validation-stress stress-tests
+docker build --build-arg IMAGE_ARCH=linux/arm64 -t torizon/rt-validation-rt rt-tests
+```
+
+
+# Run the tests (on target machine)
