+## Versioning Scheme
+
+Releases will be identified via Git tags, which will always be in the format
+
+```
+v{{ MAJOR }}.{{ MINOR }}.{{ PATCH }}
+```
+
+where `MAJOR`, `MINOR`, and `PATCH` are non-negative integers.
+
+Release version numbers are chosen by considering the following rules, in short-circuit order:
+
+* Whenever existing assertions in the test suit are changed or removed, we will bump the `MAJOR` version (with `MINOR` and `PATCH` rolling over to `0`).
+
+* Whenever new assertions are added that enhance the granularity of syntax highlighting, we will bump the `MINOR` version (with `PATCH` rolling over to `0`).
+
+* Whenever a bug is fixed, with or without adding assertions, we will bump the `PATCH` version.
+
+It's worth noting that the distinction between `MINOR` bumps and `PATCH` bumps is somewhat vague, sometimes making the decision a matter of taste. The rule defining a `MAJOR` bump, however, is unambiguous.
