+### Using system libraries
+
+By default, ruby-jq downloads and compiles its own version of libjq. If you
+would like to use your own version of libjq, you can skip this process by
+passing the `--use-system-libraries` flag to `gem install`, or by setting the
+`RUBYJQ_USE_SYSTEM_LIBRARIES` env var.
 
 ## Usage
 
 ```ruby
 require 'jq'
