+          CARA is a risk assessment tool developed to model the concentration of viruses in enclosed spaces, in order to inform space-management decisions.
+          It does this by simulating the long-range airborne spread SARS-CoV-2 virus in a finite volume, assuming homogenous mixing, and it estimates the risk of COVID-19 airborne transmission therein.
+          Please see the <a href="/about">About</a> page for more details on the methodology, assumptions and limitations of CARA.

-          <p>
-          CARA is a risk assessment tool developed to model the concentration of viruses in enclosed spaces, in order to inform space-management decisions.
-          It does this by simulating the long-range airborne spread SARS-CoV-2 virus in a finite volume, assuming homogenous mixing, and it estimates the risk of COVID-19 airborne transmission therein.
-          Please see the <a href="/about">About</a> page for more details on the methodology, assumptions and limitations of CARA.
-          </p>
-          <p>
-          The full CARA source code can be accessed freely under an Apache 2.0 open source license from our <a href="https://gitlab.cern.ch/cara/cara">code repository</a>.
-          It includes detailed instructions on how to run your own version of this tool.

+# locust
+
+A simple open source load testing tool that allows to define user behavior.
+
+In order to set it up for the first time, we followed the documentation at https://locust.io/. In particular, we:
+
+* Defined a class for the users that will be simulating.
+* Defined a ``wait_time`` variable that will make the simulated users wait between the specified seconds after each task executed.
+* Decorated our method with ``@Task`` that creates a micro-thread that calls this method.
+* Defined the ``self.client`` attribute that makes it possible to make HTTP calls that will be logged by Locust.
+
+To use, uncomment the desired method on ``lucust.py``` file, open the terminal on this folder and run the following command:
+
+``locust -f locust.py --host https://cara.web.cern.ch``
+
+Then, open up a browser and point it to http://localhost:8089. 
+By default we pointed out the test to our own web server.
+``Start swarming`` will trigger the simulation.
