+# Configure gvisor-containerd-shim (Shim V1)
+
+This document describes how to configure runtime options for `gvisor-containerd-shim`.
+
+The shim configuration is stored in `/etc/containerd/gvisor-containerd-shim.toml`.  The configuration file supports two values.
+
+`runc_shim`: The path to the runc shim. This is used by the gvisor-containerd-shim to run normal containers.
+`runsc_config`: This is a set of key/value pairs that are converted into `runsc` command line flags. You can learn more about which flags are available by running `runsc flags`.
+
+## Example: Enable the KVM platform
+
+gVisor enables the use of a number of platforms. This configuration enables the
+KVM platform.
+
+Find out more about platform in the
+(gVisor documentation)[https://gvisor.dev/docs/user_guide/platforms/].
+
+```shell
+cat <<EOF | sudo tee /etc/containerd/gvisor-containerd-shim.toml
+[runsc_config]
+platform = "kvm"
+EOF
+```
+
+## 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/gvisor-containerd-shim.toml
+# This is the path to the default runc containerd-shim.
+runc_shim = "/usr/local/bin/containerd-shim"
+[runsc_config]
+  debug=true
+  debug-log=/var/log/%ID%/gvisor.log
+EOF
+```
