 ### VRS Versioning
 
 The variation-normalization repo depends on VRS models, and therefore each variation-normalizer package on PyPI uses a particular version of VRS. The correspondences between packages may be summarized as:
 
 | variation-normalization branch | variation-normalizer version | gene-normalizer version | VRS version |
 | ---- | --- | ---- | --- |
 | [main](https://github.com/cancervariants/variation-normalization/tree/main) | 0.6.X | 0.1.X | [1.X.X](https://github.com/ga4gh/vrs) |
-| [staging](https://github.com/cancervariants/variation-normalization/tree/staging) | 0.8.X | 0.3.X | [2.0-alpha](https://github.com/ga4gh/vrs/tree/2.0-alpha) |
