+# Gitlab runners
+
+There are three types of runners with increasing levels of access to cluster secrets.
+
+1. `public`
+2. `protected`
+3. `signing`
+
+## Public & Protected runners
+
+The `public` and `protected` runners provide multiple architectures and base OSs that run across a range of AWS nodes.
+
+* Windows
+  * `x86_64_v2`
+* Linux
+  * `x86_64_v2`
+  * `x86_64_v3`
+  * `x86_64_v4`
+  * `graviton2`
+  * `graviton3`
+
+### Special Variables
+
+* `CI_OIDC_REQUIRED`: available to be set for runners with the `service` tag.
+  This variable can be used to skip OIDC configuration.
+
+## Signing Runners
+
+The `signing` runners use either `x86_64_v3` or `x86_64_v4` Linux machines.
