+## Versioning
+
+the autoBIGS project follows [semantic versioning](https://semver.org/) where the three numbers may be interpreted as MAJOR.MINOR.PATCH.
+
+Note regarding major version 0 ([spec item 4](https://semver.org/#spec-item-4)), the following adaptation of semantic versioning definition is as follows:
+
+1. Given x.Y.z, Y is only incremented when a backwards incompatible change is made.
+
+2. Given x.y.Z, Z is only incremented when a backwards compatible change is made.
+
+Versions of autoBIGS items with a major version number of 0 will introduce numerous changes and patches. As such, changes between such versions should be considered highly variable.
