## TLDR;
-1. Use afl-clang-lto/afl-clang-lto++ because it is faster and gives better
+1. This compile mode is very frickle if it works it is amazing, if it fails
+ - well use afl-clang-fast
+
+2. Use afl-clang-lto/afl-clang-lto++ because it is faster and gives better
coverage than anything else that is out there in the AFL world
-2. You can use it together with llvm_mode: laf-intel and whitelisting
+3. You can use it together with llvm_mode: laf-intel and whitelisting
features and can be combined with cmplog/Redqueen
-3. It only works with llvm 9 (and likely 10+ but is not tested there yet)
+4. It only works with llvm 9 (and likely 10+ but is not tested there yet)
