-2. Configure `/etc/containerd/runsc.toml` with the desired options. The set of options that can be configured can be found in [options.go](../pkg/v2/options/options.go). This example shows how to configure `containerd-shim-runsc-v1` to use gvisor with the kvm platform.
+### Configure `/etc/containerd/runsc.toml`
+
+The set of options that can be configured can be found in
+[options.go](../pkg/v2/options/options.go).
+
+#### Example: Enable the KVM platform
+
+gVisor enables the use of a number of platforms. This example shows how to
+configure `containerd-shim-runsc-v1` to use gvisor with the KVM platform.
+
+Find out more about platform in the
+(gVisor documentation)[https://gvisor.dev/docs/user_guide/platforms/].
 
 ```shell
-{ # Step 2: Create containerd-shim-runsc-v1 runtime options config
 cat <<EOF | sudo tee /etc/containerd/runsc.toml
 [runsc_config]
 platform = "kvm"
 EOF
-}
 ```
 
-3. Restart `containerd`
+### Example: Enable gVisor debug logging
+
+gVisor debug logging can be enabled by setting the `debug` and `debug-log`
+flag. The shim will replace "%ID%" with the container ID in the path of the
+`debug-log` flag.
+
+Find out more about debugging in the
+(gVisor documentation)[https://gvisor.dev/docs/user_guide/debugging/].
+
+```shell
+cat <<EOF | sudo tee /etc/containerd/runsc.toml
+[runsc_config]
+  debug=true
+  debug-log=/var/log/%ID%/gvisor.log
+EOF
+```
+
+## Restart `containerd`
+
+When you are done restart containerd to pick up the new configuration files.
 
 ```shell
 sudo systemctl restart containerd
