+# Secret Manager
+
+A simple CLI tool to manage Kubernetes Secrets from your local machine. It handles Base64 encoding/decoding automatically, allowing you to work with plain text values.
+
+## Features
+
+- **List**: View all keys and values in a secret (decoded).
+- **Add/Update**: Add a new key-value pair or update an existing one using plain text.
+- **Delete**: Remove a specific key from a secret.
+
+## Prerequisites
+
+- Local `kubeconfig` file (usually at `~/.kube/config`).
+- `cluster-admin` or sufficient RBAC permissions to manage secrets in the target namespace.
+
+## Build
+
+From the root of the repository:
+
+```bash
+make build
+# The binary will be located at bin/secret-manager
+```
+
+## Usage
+
+```bash
+./bin/secret-manager --secret <name> [options]
+```
+
+### Options
+
+- `--namespace`: Namespace of the secret (default: `default`).
+- `--secret`: **(Required)** Name of the Kubernetes secret.
+- `--op`: Operation to perform: `list`, `add`, or `delete` (default: `list`).
+- `--key`: The key to add or delete.
+- `--value`: The plain text value to add (required for `add` operation).
+- `--kubeconfig`: Path to a custom kubeconfig file.
+
+### Examples
+
+**1. List keys and values:**
+```bash
+./bin/secret-manager --namespace gps-system --secret test-daemonset-7v1v1 --op list
+```
+
+**2. Add or update a key:**
+```bash
+./bin/secret-manager --namespace gps-system --secret test-daemonset-7v1v1 --op add --key my-key --value "my-value"
+```
+
+**3. Delete a key:**
+```bash
+./bin/secret-manager --namespace gps-system --secret test-daemonset-7v1v1 --op delete --key my-key
+```
