+### Important Security Note
 
 We do not recommend running Element from the same domain name as your Matrix homeserver (Synapse). The reason is the risk of XSS (cross-site-scripting) vulnerabilities that could occur if someone caused Element to load and render malicious user generated content from a Matrix API which then had trusted access to Element (or other apps) due to sharing the same domain.
 
-We have put some coarse mitigations into place to try to protect against this situation, but it's still not good practice to do it in the first place. See vector-im/element-web#1977 for more details.
