+## Contributor Ladder

+We've designed a clear progression path that recognizes your growing expertise and contributions. For complete details on contributor roles and how to advance from contributor to maintainer, please check out our [Contributor Ladder](https://github.com/WasmEdge/WasmEdge/blob/master/docs/CONTRIBUTOR_LADDER.md)).
