 Users install NVDA add-ons at their own risk.
 Therefore, the following considerations should be kept in mind when installing them:
-- Check out the developer’s website to see if it’s a serious source you can trust.
+- If the developer has a website, spend some time evaluating whether it appears to be a serious source you can trust.
 - Read the description carefully. Does the add-on need questionable permissions? Does it track data? Does it share sensitive data with other sources that you don’t trust?
 - Check out the [community reviews #AddonStoreReviews] for the add-on. Are there any complaints about the add-on? Are there any reports about data being taken, or for anything that makes you feel unsafe?
 - The risk of vulnerabilities increases the more add-ons you installed. So be careful to keep the overview of the sources your add-ons come from.
