+ICE validation scripts
+======================
+
+The ICE validation scripts are based on the python ``pytest`` tool.
+These scripts check that the Heat Templates are compliant with the ONAP Heat Template Guidelines.
+
+Installation
+------------
+
+This software is not platform dependent and can be run in a Windows, Unix or
+OS X environment.
+
+- Install python 2.7 or python 3
+- Install pip
+
+In addition to python, this project requires the following packages:
+
+- pytest
+- PyYAML
+
+Depending on the desired output format, you should add the following optional packages:
+
+- pytest-tap
+- pytest-html
+
+These can be installed using pip (assuming pip is installed) with the command:
+
+``$ pip install pytest PyYAML pytest-tap pytest-html``
+
+Usage
+-----
+
+Retrieve the ICE scripts, by cloning the sources:
+
+``$ git clone https://git.onap.org/vnfsdk/ice``
+
+Go into the ice_validator directory:
+
+``$ cd ice/validation-scripts/ice_validator``
+
+The Heat templates validation may generate different ouput format (plain, tap, html):
+
+- plain format
+
+``$ pytest --template-directory=<Directory>``
+
+- tap format
+
+``$ pytest --tap-stream --template-directory=<Directory>``
+
+- html format
+
+``$ pytest --html=/path/to/report.html --template-directory=<Directory>``
+
+NB: ``<Directory>`` is the absolute path of the folder containing the Heat
+Templates to be verified.
