+If you want to install cosign from its main version by using 'go install' under the hood, you can set 'cosign-release' as 'main'. Once you did that, cosign will be installed via 'go install' which means that please ensure that go is installed.
+
+Example of installing cosign via go install:
+
+```yaml
+jobs:
+  test_cosign_action:
+    runs-on: ubuntu-latest
+
+    permissions:
+      actions: none

+    name: Install Cosign via go install
