+=======================
+Vendored library policy
+=======================
+
+To simplify Bleach development, we're now vendoring certain libraries that
+we use.
+
+Vendored libraries must follow these rules:
+
+1. Vendored libraries must be pure Python--no compiling.
+2. Source code for the libary is included in this directory.
+3. License must be included in this repo and in the Bleach distribution.
+4. Requirements of the library become requirements of Bleach.
+5. No modifications to the library may be made.
+
+
+Adding/Updating a vendored library
+==================================
+
+Way to vendor a library or update a version:
+
+1. Update ``vendor.txt`` with the library, version, and hash. You can use 
+   `hashin <https://pypi.org/project/hashin/>`_.
+2. Remove all old files and directories of the old version.
+3. Run ``pip_install_vendor.sh`` and check everything it produced in including
+   the ``.dist-info`` directory and contents.
+
+
+Reviewing a change involving a vendored library
+===============================================
+
+Way to verify a vendored library addition/update:
+
+1. Pull down the branch.
+2. Delete all the old files and directories of the old version.
+3. Run ``pip_install_vendor.sh``.
+4. Run ``git diff`` and verify there are no changes.
