+# Aegis Helm Chart
+
+Aegis keeps your secrets secret. With Aegis, you can rest assured that your sensitive data is always secure and protected. Aegis is perfect for securely storing arbitrary configuration information at a central location and securely dispatching it to workloads.
+
+## Installation
+
+To use Aegis, follow the steps below:
+
+1. Add Aegis Helm repository:
+
+    ```bash
+    helm repo add aegis https://shieldworks.github.io/aegis/
+    ```
+
+2. Update helm repository:
+
+    ```bash
+    helm repo update
+    ```
+
+3. Install Aegis using Helm:
+
+    ```bash
+    helm install aegis aegis/aegis --version 0.1.0
+    ```
+
+## Options
+
+The following options can be passed to the `helm install` command to set global variables:
+
+- `--set global.deploySpire=<true/false>`: This flag can be passed to install or skip Spire.
+- `--set global.baseImage=<distroless/distroless-fips/photon/photos-fips>`: This flag can be passed to install Aegis with the given baseImage Docker image.
+
+Default values are `true` and `distroless` for `global.deploySpire` and `global.baseImage` respectively.
+
+Here's an example command with the above options:
+
+```bash
+helm install aegis aegis/helm-charts --version 0.1.0 --set global.deploySpire=true --set global.baseImage=distroless
+```
+
+Make sure to replace `<true/false>` and `<distroless/distroless-fips/photon/photos-fips>` with the desired values.
