 Some users choose to disable JIT as a hardening measure against theoretical browser exploits. This is a reasonable choice if you face targeted attacks from well-resourced adversaries (such as nation-state actors), but it comes with real performance costs.
 
 If you've disabled JIT and find Anubis checks slow, re-enabling JIT is the fix. There is no way for Anubis to work around this on our end.

+## What versions of browsers does Anubis support?
+
+Anubis is written mainly by a single person in a basement in Canada. As such it is impossible for Anubis to support every version of every browser on the planet. As such, here's a few rules of thumb for the browsers that Anubis focuses on supporting:
+
+- At least the two (2) most recent LTS releases of Firefox and Chrome.
+- At least the version of Chromium as used by the Samsung Browser on Android.
+- At least the last version of Chromium and Firefox that are known to run on Windows 7.
+- At least the version of Safari that runs on the second-to-oldest iPhone model currently on the market.
+
+We cannot give more cohesive version bounds than this. If you run into problems, please file an issue. Sometimes you may just need to upgrade hardware though.
