 Clicking on a pipeline will show the builds that were run for that pipeline.
+## Badges
+
+There are build status and test coverage report badges available.
+
+Go to pipeline settings to see available badges and code you can use to embed
+badges in the `README.md` or your website.
+
+### Build status badge
+
+You can access a build status badge image using following link:
+
+```
+http://example.gitlab.com/namespace/project/badges/branch/build.svg
+```
+
+### Test coverage report badge
+
+GitLab makes it possible to define the regular expression for coverage report,
+that each build log will be matched against. This means that each build in the
+pipeline can have the test coverage percentage value defined.
+
+You can access test coverage badge using following link:
+
+```
+http://example.gitlab.com/namespace/project/badges/branch/coverage.svg
+```
+
+If you would like to get the coverage report from the specific job, you can add
+a `job=coverage_job_name` parameter to the URL. For example, it is possible to
+use following Markdown code to embed the est coverage report into `README.md`:
+
+```markdown
+![coverage](http://gitlab.com/gitlab-org/gitlab-ce/badges/master/coverage.svg?job=coverage)
+```
