In readme, link formatting is backwards ((Katacoda)[https://www.katacoda.com/patternfly] should be [Katacoda](https://www.katacoda.com/patternfly))
Links to component docs are outdated (ex: https://www.patternfly.org/v4/documentation/core/components/chip should now be https://www.patternfly.org/v4/components/chip)
Links to developer get started page are incorrect (https://www.patternfly.org/v4/get-started/developers should be https://www.patternfly.org/v4/get-started/develop)
Links to charts docs go to 404, these can link to docs site rather than react workspace (ex: https://patternfly-react.surge.sh/patternfly-4/charts/chartpie/ becomes https://www.patternfly.org/v4/charts/pie-chart)
A few groups of broken links:
