+## Local setup
+
+Clone the reposistory to your machine and install the required dependencies.
+
+### Create a virtual environment
+
+```fish
+python3 -m venv.venv
+```
+
+### Install dependencies
+
+```fish
+pip install -r requirements.txt
+```
+
+### Demo script
+
+This demo python script will create, read, update and delete secrets via the SDK. Just update the host, app, env and token constants at the top.
+
+```python
+from src.phase import Phase, CreateSecretsOptions, GetAllSecretsOptions, UpdateSecretOptions, DeleteSecretOptions
+
+CONSOLE_HOST = 'https://console.phase.dev'
+APP_NAME = '<app-name>'
+ENV_NAME = "<env-name>"
+TOKEN = '<service-token>'
+
+# Initialize the Phase object with host and service token
+phase = Phase(init=False,
+    pss=TOKEN,
+    host=CONSOLE_HOST)
+
+# Create secrets with references
+create_options = CreateSecretsOptions(
+    env_name=ENV_NAME,
+    app_name=APP_NAME,
+    key_value_pairs=[
+        {"BASE_URL": "https://api.example.com"},
+        {"API_ENDPOINT": "${BASE_URL}/v1/data"},
+        {"NESTED_REF": "Nested ${API_ENDPOINT}"}
+    ]
+)
+create_result = phase.create_secrets(create_options)
+print(f"Create secrets result: {create_result}")
+
+# Read and resolve references
+get_options = GetAllSecretsOptions(
+    env_name=ENV_NAME,
+    app_name=APP_NAME
+)
+secrets = phase.get_all_secrets(get_options)
+
+resolved_secrets = phase.resolve_references(secrets, ENV_NAME, APP_NAME)
+
+print("\nResolved Secrets:")
+print("----------------")
+for secret in resolved_secrets:
+    print(f"{secret.key}: {secret.value}")
+
+# Update secrets
+update_options = UpdateSecretOptions(
+    env_name=ENV_NAME,
+    app_name=APP_NAME,
+    key="BASE_URL",
+    value="https://api.acme.com",
+    secret_path="/",
+    destination_path="/",  # Optional: move secret to a new path
+    override=False,  # Optional: create a personal override
+    toggle_override=False  # Optional: toggle personal override
+)
+update_result = phase.update_secret(update_options)
+
+print(f"\nUpdate secrets result: {update_result}")
+print("----------------")
+
+
+## Refetch secrets
+secrets = phase.get_all_secrets(get_options)
+
+resolved_secrets = phase.resolve_references(secrets, ENV_NAME, APP_NAME)
+
+print("\nResolved Secrets:")
+print("----------------")
+for secret in resolved_secrets:
+    print(f"{secret.key}: {secret.value}")
+
+
+# Delete secrets
+delete_options = DeleteSecretOptions(
+    env_name=ENV_NAME,
+    app_name=APP_NAME,
+    key_to_delete="BASE_URL",
+    secret_path="/"
+)
+result = phase.delete_secret(delete_options)
+print(f"Delete result: {result}")
+
+## Refetch secrets
+secrets = phase.get_all_secrets(get_options)
+
+resolved_secrets = phase.resolve_references(secrets, ENV_NAME, APP_NAME)
+
+print("\nResolved Secrets:")
+print("----------------")
+for secret in resolved_secrets:
+    print(f"{secret.key}: {secret.value}")
+```
