+## CircleCI Integration
+
+Enable CircleCI support in your `build.sbt`:
+
+```scala
+import org.scoverage.coveralls.Imports.CoverallsKeys._
+import org.scoverage.coveralls.CircleCI
+
+coverallsService := Some(CircleCI)
+```
+
+Add the following step to your `config.yml` right after your test step:
+
+```yaml
+- run:
+    name: Generate and upload coverage report
+    when: always
+    command: sbt ";coverageReport ;coverageAggregate ;coveralls"
+```
+
