+Remember to create a title following the Conventional Commits guidelines. Examples for valid PR titles are:
+
+fix: Some thing found in the repo
+feat: Add some feature
+refactor!: Make some refactor
+feat(wallet-connect): Add some feature
+
+Note that since PR titles only have a single line, you have to use the ! syntax for breaking changes.
