 Python Package Index (PyPI). This package is particularly useful for users who want to retrieve and analyze metadata for packages
 maintained by a specific PyPI user.
 
+## Significant Update From 0.1.3
+
+pypi.org no longer allow you to scrap details using the requests package, or any package that does not support JavaScript. To resolve this we have
+updated this package to utilise [PlayWright](https://pypi.org/project/playwright/) when retrieving a list of packages for a given user. While we have 
+attempted to automate as much as possible you might want to do some of the work manually.
+
+Playwright needs two commands to be run in order for it to function correctly:
+
+```
+playwright install
+playwright install-deps
+```
+
+We have added an `auto_install` option to the main class so that you can instruct the package to do the install for you, this helps when installing the
+package in a fully automated way, e.g. Puppet or similar.
+
 ## Features
 
 - Retrieve a list of packages maintained by a specific PyPI user.
