+### Custom Compose Compiler
+
+Each version of Molecule ships with a specific JetBrains Compose compiler version which works with
+a single version of Kotlin (see [version table](#Usage) above). Newer versions of the Compose
+compiler or alternate Compose compilers can be specified using the Gradle extension.
+
+To use a new version of the JetBrains Compose compiler version:
+```kotlin
+molecule {
+  kotlinCompilerPlugin.set("1.4.8")
+}
+```
+
+To use an alternate Compose compiler dependency:
+```kotlin
+molecule {
+  kotlinCompilerPlugin.set("com.example:custom-compose-compiler:1.0.0")
+}
+```
