 ### How to generate the JUnit result files
 
-You just have to execute Robot Framework with `-x` parameter followed by the xml result file name to instruct it to generate the JUnit result file. For testing purposes, you can clone this project and execute Robot Framework like so:
+You just have to execute Robot Framework with `-x` parameter followed by the xml result file name to instruct it to generate the JUnit result file. Here is an example:
 
 ```
-robot -x junitresult.xml calculator.robot
+robot -x junitresult.xml mytest.robot
+```
+
+This will execute `mytest.robot` test file and generate the JUnit result file `junitresult.xml` that you'll [`POST /automations/executions/junit`](https://support.smartbear.com/zephyr-scale-cloud/api-docs/#operation/createJUnitExecutions).
+
+
+### Requirements to run this example project
+
+In order to execute this example on your local machine you’ll have to checkout this repository and install python 3. Here is how you can do it on mac:
+
+```
+brew upgrade pyenv
+pyenv install 3.6.0
+pyenv global 3.6.0
+echo 'eval "$(pyenv init -)"' >> ~/.zshrc
+source ~/.zshrc
 ```
 
-This will generate the JUnit result file `junitresult.xml` that you'll [`POST /automations/executions/junit`](https://support.smartbear.com/zephyr-scale-cloud/api-docs/#operation/createJUnitExecutions).
+Now you have to install robot framework and docutils library:
+
+```
+pip install robotframework
+pip install docutils
+```
+
+You can now make Robot Framework to generate the JUnit result file by executing the following command:
+
+```
+robot -x junitresult.xml calculator.robot
+```
