+# Go on Docker Hub
+
+Dagger stand as a powerful CI/CD tool that works on any environment.
+
+For instance, you can use [go package](https://github.com/dagger/dagger/tree/main/pkg/universe.dagger.io/go)
+to control the whole CI/CD process, from test to push into a remote registry.
+
+:::tip
+Following examples can be used as a template for any standalone go project.
+:::
+
+## Test
+
+```cue file=../tests/use-cases/ci-cd-for-go-project/test/dagger.cue
+```
+
+You can then run unit test in your go project with
+
+```shell
+dagger do unit-test
+```
+
+<!-- FIXME: we should write a bunch of documentation about TDD with dagger -->
+:::tip
+You can also use dagger to write integration tests
+:::
+
+## Build
+
+```cue file=../tests/use-cases/ci-cd-for-go-project/build/dagger.cue
+```
+
+:::tip
+You can control the binary platform with `os` and `arch` field.
+:::
+
+You can then build your binary with
+
+```shell
+dagger do build
+```
+
+## Push
+
+```cue file=../tests/use-cases/ci-cd-for-go-project/push/dagger.cue
+```
+
+You can then build and push your go project with
+
+```shell
+dagger do push
+```
+
+## Push multi-platform
+
