 The following [`.gitlab-ci.yml`](../../../ci/yaml/index.md) example for Go uses:

+- [`gocover-cobertura`](https://github.com/boumenot/gocover-cobertura) to convert Go's coverage profile into the Cobertura XML format.
 
-This example assumes that [Go modules](https://go.dev/ref/mod) are being used.
-Using Go modules causes paths within the coverage profile to be prefixed with your
-project's module identifier, which can be found in the `go.mod` file. This
-prefix must be removed for GitLab to parse the Cobertura XML file correctly. You can use the following `sed` command to remove the prefix:
-
-```shell
-sed -i 's;filename=\"<YOUR_MODULE_ID>/;filename=\";g' coverage.xml
-```
-
-Replace the `gitlab.com/my-group/my-project` placeholder in the following example with your own module identifier to make it work.
+This example assumes that [Go modules](https://go.dev/ref/mod)
+are being used. Please note that the `-covermode count` option does not work with the `-race` flag.
+If you want to generate code coverage while also using the `-race` flag, you must switch to
+`-covermode atomic` which is slower than `-covermode count`. See [this blog post](https://go.dev/blog/cover)
+for more details.
