 # Publication validator
 
-This is a supplementary subproject of kotlinx.coroutines to test its publication correctness.
+This is a supplementary subproject of kotlinx.coroutines that provides a new
+task, `testPublishing`, to test its publication correctness.
 
-It is used as part of "Dependency validation" build chain on TeamCity:
-* kotlinx.corotoutines are built with `publishToMavenLocal`
-* kotlinx.coroutines are built with `npmPublish -PdryRun=true` to have a packed publication
+The tests are the following:
 * `NpmPublicationValidator` tests that version of NPM artifact is correct and that it has neither source nor package dependencies on atomicfu
 * `MavenPublicationValidator` depends on the published artifacts and tests artifacts binary content and absence of atomicfu in the classpath
+
+To test publication, one needs to run gradle with `-PdryRun=true`, and the
+task that actually does the testing is `publication-validator:test`.
+`-PdryRun` affects `npmPublish` so that it only provides a packed publication
+and does not in fact attempt to send the build for publication.
