@@ -8,3 +8,21 @@ The support for cross-compilation is currently under development.
 File created there, `config.bzl`, consists of many variables. In particular:
 * `SCALA_VERSION` – representing the default Scala version, e.g. `"3.3.1"`;
 * `SCALA_VERSIONS` – representing all configured Scala versions (currently one), e.g. `["3.3.1"]`.
+
+
+## Version-dependent behavior
+Don't rely on `SCALA_VERSION` as it represents the default Scala version, not necessarily the one that is currently requested.
+
+If you need to customize the behavior for specific Scala version, there are two scenarios.
+
+### From toolchain
+If you have an access to the Scala toolchain (`@io_bazel_rules_scala//scala:toolchain_type`), there is `scala_version` field provided in there:
+```starlark
+def _rule_impl(ctx):
+    ...
+    ctx.toolchains["@io_bazel_rules_scala//scala:toolchain_type"].scala_version
+    ...
+```
+
+### From config setting
