+# Metadata Service Package
+
+🔍 This package provides a set of tools for managing metadata. It includes a `MetadataService` for handling metadata operations and a `MetadataProvider` for providing metadata context to React components.

+
+## Getting started
+
+First, install the package in your project:
+
+```bash
+yarn add metadata-service
+```
+
+### MetadataProvider
+
+Wrap your application in the `MetadataProvider`:
+
+```jsx
+import { MetadataProvider } from "metadata-service";
+
+function App() {
+  return (
+    <MetadataProvider>
+      <YourComponent />
+    </MetadataProvider>
+  );
+}
+```
+
+Now you can use the `useMetadata` hook to access metadata context in your components:
+
+```jsx
+import { useMetadata } from "metadata-service";
+
+function YourComponent() {
+  const metadata = useMetadata();
+
+  // Use the metadata here...
+
+  return <div>{/* Your component's JSX... */}</div>;
+}
+```
+
+### MetadataService
+
+You can also use the `MetadataService` directly to perform metadata operations:
+
+```jsx
+import { MetadataService } from "metadata-service";
+
+const metadataService = new MetadataService({
+  cip: CIP_Reference["0108"],
+  hashAlgorithm: "blake2b-256",
+  body: {
+    title: "My title",
+    abstract: "My abstract",
+    motivation: "My motivation",
+    rationale: "My rationale",
+    references: [{ label: "some url", uri: "http://some.url" }],
+  },
+});
+
+metadataService.initialize().then((service) => {
+  // ...use the service here
+});
+```
