+Library dependency
+==================
+
+This document defines the qualification criteria for external libraries that may be
+used as dependencies in DPDK drivers or libraries.
+
+- **Free availability**: The library must be freely available to build in either source or binary
+  form, with a preference for source form.
+
+- **Compiler compatibility**: The library must be able to compile with a DPDK supported compiler
+  for the given execution environment. For example, For Linux, the library must be able to compile
+  with GCC and/or clang.
+
+- **Documentation**: Must have adequate documentation for the steps to build it.
+
+- **Meson build integration**: The library must have standard method like ``pkg-config``
+  for seamless integration with DPDK's build environment.
+
+- **Code readability**: When the depended library is optional, use stubs to reduce the ``ifdef``
+  clutter to enable better code readability.
