+### Security
+
+Many users of this module process untrusted, user-supplied images,
+but there are aspects of security to consider when doing so.
+
+It is possible to compile libvips with support for various third-party image loaders.
+Each of these libraries has undergone differing levels of security testing.
+
+Whilst tools such as [American Fuzzy Lop](http://lcamtuf.coredump.cx/afl/)
+and [Valgrind](http://valgrind.org/) have been used to test
+the most popular web-based formats, as well as libvips itself,
+you are advised to perform your own testing and sandboxing.
+
+ImageMagick in particular has a relatively large attack surface,
+which can be partially mitigated with a
+[policy.xml](http://www.imagemagick.org/script/resources.php)
+configuration file to prevent the use of coders known to be vulnerable.
+
+```xml
+<policymap>
+  <policy domain="coder" rights="none" pattern="EPHEMERAL" />
+  <policy domain="coder" rights="none" pattern="URL" />
+  <policy domain="coder" rights="none" pattern="HTTPS" />

+Set the `MAGICK_CONFIGURE_PATH` environment variable
+to the directory containing the `policy.xml` file.

+Greater libvips performance can be expected with caching enabled (default)
+and using 8+ core machines, especially those with larger L1/L2 CPU caches.

 The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
