 # Secure Coding with Python.
 
 ## Chapter 1: Project Bootstrap
-### Testing
-In order to make sure our libraries don't containg any know vulnerabilities, we can use a dependency scanner such as [Safety](https://pyup.io/safety/).
-
-```
- > $ pip install safety
- > $ safety check -r requirements.txt --full-report

+### Fix
+In this case the fix is extremely simple, we just need up upgrade Flask to 1.0.3 in the `requirements.txt` file and run:
+```bash
+> pip install -r requirements.txt --upgrade
 ```
-**Note:** The free version of safety updates it's database once a month, so latest vulnerabilities might not show up. For better security a paid API key can be used to get more up-to-date releases information.
-
-We can start building our CI build script with a simple dependency vulnerabilities check using [Safety](https://pyup.io/safety/) as shown in build.sh
