+"Permissive" Scudo
+------------------
+
+It may be useful to *first* try using Scudo in its most permissive, most
+performant mode, and then remove/add options to make Scudo more secure, based
+on your application's needs.
+
+The recommended settings for such usage are as follows:
+
+.. code::
+
+  QuarantineSizeKb=0;ThreadLocalQuarantineSizeKb=0;abort_on_error=1;DeallocationTypeMismatch=false;DeleteSizeMismatch=false"
+
+The first two settings completely disable the quarantine.
+
+`abort_on_error` has Scudo print stack traces when it encounters a memory
+error, which is useful for uncovering the root cause of such errors, if your
+application encounters them frequently, but is not recommended for production
+use.
+
+The last two options disable the checks for a few additional types of memory
+errors that Scudo can check for.
