 ## Reporting a Vulnerability
 
-If you believe you have identified a security issue with Python-dotenv, please email
+If you believe you have identified a security issue with python-dotenv, please email
 python-dotenv@saurabh-kumar.com. A maintainer will contact you acknowledging the report
 and how to continue.
 
 Be sure to include as much detail as necessary in your report. As with reporting normal
 issues, a minimal reproducible example will help the maintainers address the issue faster.
-If you are able, you may also include a fix for the issue generated with `git
-format-patch`.
