+### Delete oldest x number of versions while ignoring particular package versions in the same repo as the workflow
+
+To delete oldest x number of versions while ignoring all the major package versions in the same repo as the workflow the __package-name__, __num-oldest-versions-to-delete__ and __ignore-versions__ inputs are required.
+
+There is a possibility if the oldest x number of versions contain ignored package versions, actual package versions to ge deleted will be less than x.
+
+__Example__
+
+Delete 3 oldest versions excluding major versions as per semver is the same repo as the workflow
+
+```yaml

+  with: 
+    package-name: 'test-packae'

+```
+
+### Delete all pre-release package versions in the same repo as the workflow
+
+To delete all pre release package versions in the same repo as the workflow the __package-name__ and __delete-only-pre-release-versions__ inputs are required.
