 # Hosts Loader
 
 Burp plugin to automatically load hosts from /etc/hosts (or the Windows equivalent) into Burp's project hostname resolution override.
+Supports adding custom dns hosts from dnsmasq on Linux.(`address=/custom1.tld/custom2.tld/custom3.tld/.../10.10.10.10`)
 
 ## Why?
 
-When I'm doing HackTheBox, changing my /etc/hosts doesn't seem to work for resolving things in Burp Suite. I assume they're cached in some way, but honestly it was quicker to write this then debug why this happens.
+When I'm doing HackTheBox or Vulnlab, changing my /etc/hosts (or the Windows equivalent or dnsmasq) doesn't seem to work (or I forget to reload dnsmasq) for resolving things in Burp Suite. I assume they're cached in some way, but honestly it was quicker to write this than try to debug why this happens.
 
 ## How to use
 
-Install the jar as you would any other extension. A new tab will appear, click reload, and hosts will be loaded.
