+By default, having a branch named: `feat/ticket-123-be-crete-feature-foo`
+
+Default behaviour:
+- `TICKET-123 Be create feature foo`
+
+With `PR_TITLE_REMOVE_PREFIX=be` the result will be:
+- `TICKET-123 Create feature foo`
+
+> This variable accept multiple strings to consider/remove comma separated.
