 ### Building for different versions of IntelliJ IDEA and Android Studio
 
-Kotlin plugin is intended to work with several recent versions of IntelliJ IDEA and Android Studio. Each platform is allowed to have a different set of features and might provide a slightly different API. Instead of using several parallel Git branches, the project stores everything in a single branch, but files may have counterparts with version extensions (\*.as32, \*.172, \*.181). The primary file is expected to be replaced with its counterpart when targeting a non-default platform.

+More detailed description of this scheme can be found at https://github.com/JetBrains/bunches/blob/master/ReadMe.md.
 
 Usually, there's no need to care about multiple platforms as all features are enabled everywhere by default. Additional counterparts should be created if there's an expected difference in behavior or an incompatible API usage is required **and** there's no reasonable workaround to save source compatibility. Kotlin plugin contains a pre-commit check that shows a warning if a file has been updated without its counterparts.

-### Dependency verification
+### Including into composite build
 
-We have a [dependencies verification](https://docs.gradle.org/current/userguide/dependency_verification.html) feature enabled in the
-repository for all Gradle builds. Gradle will check hashes (md5 and sha256) of used dependencies and will fail builds with
-`Dependency verification failed` errors when local artifacts are absent or have different hashes listed in the
-[verification-metadata.xml](https://github.com/JetBrains/kotlin/blob/master/gradle/verification-metadata.xml) file.
+To include kotlin compiler into [composite build](https://docs.gradle.org/current/userguide/composite_builds.html) you need to define `dependencySubstitution` for `kotlin-compiler` module in `settings.gradle.kts`
 
-It's expected that `verification-metadata.xml` should only be updated with the commits that modify the build. There are some tips how
-to perform such updates:
+```Kotlin
+includeBuild("/path/to/kotlin") {
+    dependencySubstitution {
+        substitute(module("org.jetbrains.kotlin:kotlin-compiler"))
+            .with(project(":include:kotlin-compiler"))
+    }
+}
+```
 
-- Use auto-generation for getting an initial list of new hashes (verify updates relate to you changes).
+or in `settings.gradle`
 
-`./gradlew -M sha256,md5 help`
-
-*(any other task may be used instead of `help`)*
-
-- Consider removing old versions from the file if you are updating dependencies.
-- Leave meaningful `origin` attribute (instead of `Generated by Gradle`) if you did some manual verification of the artifact.
-- Always do manual verification if several hashes are needed and a new `also-trust` tag has to be added.
-- If you’re adding a dependency with OS mentioning in an artifact name (`darwin`, `mac`, `osx`, `linux`, `windows`), remember to add 
-  counterparts for other platforms.
+```Groovy
+includeBuild('/path/to/kotlin') {
+    dependencySubstitution {
+        substitute module('org.jetbrains.kotlin:kotlin-compiler') with project(':include:kotlin-compiler')
+    }
+}
+```
