+## Private Registry Authentication
 
-**Recommended (macOS and Linux)**
-```bash
-# install the latest version to /usr/local/bin
-curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b /usr/local/bin
+### Local Docker Credentials
+When a container runtime is not present, Syft can still utilize credentials configured in common credential sources (such as `~/.docker/config.json`). 
+It will pull images from private registries using these credentials. The config file is where your credentials are stored when authenticating with private registries via some command like `docker login`. 
+For more information see the `go-containerregistry` [documentation](https://github.com/google/go-containerregistry/tree/main/pkg/authn).
 
-# install a specific version into a specific dir
-curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b <SOME_BIN_PATH> <RELEASE_VERSION>
+
+An example `config.json` looks something like this:
+```
+// config.json
+{
+	"auths": {
+		"registry.example.com": {
+			"username": "AzureDiamond",
+			"password": "hunter2"
+		}
+	}
+}
 ```
 
-**Homebrew (macOS)**
-```bash
-brew tap anchore/syft
-brew install syft
-```
+You can run the following command as an example. It details the mount/environment configuration a container needs to access a private registry:
+
+`docker run -v ./config.json:/config/config.json -e "DOCKER_CONFIG=/config" anchore/syft:latest  <private_image>`
+
+
+### Docker Credentials in Kubernetes
+The below section shows a simple workflow on how to mount this config file as a secret into a container on kubernetes.
+1. Create a secret. The value of `config.json` is important. It refers to the specification detailed [here](https://github.com/google/go-containerregistry/tree/main/pkg/authn#the-config-file). 
+Below this section is the `secret.yaml` file that the pod configuration will consume as a volume. 
+The key `config.json` is important. It will end up being the name of the file when mounted into the pod.
+    ```
+    # secret.yaml
+    
+    apiVersion: v1
+    kind: Secret
+    metadata:
+      name: registry-config
+      namespace: syft
+    data:
+      config.json: <base64 encoded config.json>
+    ```
+
+    `kubectl apply -f secret.yaml`
+
+
+2. Create your pod running syft. The env `DOCKER_CONFIG` is important because it advertises where to look for the credential file. 
+In the below example, setting `DOCKER_CONFIG=/config` informs syft that credentials can be found at `/config/config.json`. 
+This is why we used `config.json` as the key for our secret. When mounted into containers the secrets' key is used as the filename. 
+The `volumeMounts` section mounts our secret to `/config`. The `volumes` section names our volume and leverages the secret we created in step one.
+    ```
+    # pod.yaml
+    
+    apiVersion: v1
+    kind: Pod
+    spec:
+      containers:
+        - image: anchore/syft:latest
+          name: syft-private-registry-demo
+          env:
+            - name: DOCKER_CONFIG
+              value: /config
+          volumeMounts:
+          - mountPath: /config
+            name: registry-config
+            readOnly: true
+          args:
+            - <private_image>
+      volumes:
+      - name: registry-config
+        secret:
+          secretName: registry-config
+    ```
+
+    `kubectl apply -f pod.yaml`
+
+
+3. The user can now run `kubectl logs syft-private-registry-demo`. The logs should show the syft analysis for the `<private_image>` provided in the pod configuration.
+
+Using the above information, users should be able to configure private registry access without having to do so in the `grype` or `syft` configuration files.
+They will also not be dependent on a docker daemon, (or some other runtime software) for registry configuration and access.
