-## Basic Usage
+## How it works
+
+This library loads secrets on demand from APIs or files. For dotenv file, it is loaded at startup and saved in the cache.
+Secrets are encrypted when store in the cache with a master key generated at startup. Enables developers to access keys securely.
+
+Key features include:
+
+- FETCH and SET secrets.
+- Key fetch throttling.
+- Authentications with providers like Azure Keyvault and Google Secrets manager and token renewals.
+- Catching of secrets.
+- Default key options.
+- You can configure multiple secrets and access from different providers.
+- RESET and RELOAD secrets without shutting down your application.
