+This tutorial will give you a first overview of ReFrame and will acquaint you with its basic concepts.
 We will start with a simple "Hello, World!" test running with the default configuration and we will expand the example along the way.
 We will also explore performance tests and we will port our tests to an HPC cluster.
 The examples of this tutorial can be found under :obj:`tutorials/basics/`.

+Unless a test is rather generic, you will need to make some adaptations for the system that you port it to.
 In this case, we will adapt the STREAM benchmark so as to run it with multiple compiler and adjust its execution parameters based on the target architecture of each partition.

 Once the commands are executed, the container is stopped and ReFrame goes on with the sanity and performance checks.
 Users may also change the default mount point of the stage directory by using :attr:`workdir <reframe.core.pipeline.RegressionTest.container_platform.workdir>` attribute:
