-# @design.estate/private/dedocument-catalog
+# @design.estate/dees-document
 a catalog for creating documents like invoices
 
-## Usage
+## Install
+To install `@design.estate/dees-document`, run the following command in your project directory:
+```shell
+npm install @design.estate/dees-document --save
+```
 
-Use TypeScript for best in class intellisense
-For further information read the linked docs at the top of this readme.
+This will add `@design.estate/dees-document` to your project's dependencies and ensure it's installed into your `node_modules` folder.
+
+## Usage
+The `@design.estate/dees-document` package is a comprehensive toolkit for creating various types of documents, such as invoices, with ease. It leverages modern ECMAScript (ES) modules and TypeScript for a type-safe, developer-friendly experience. Below, you'll find detailed examples covering how to utilize the package to its full potential.
+
+### Setting Up the Document Service
+Before diving into creating documents, you first need to set up the document service. This involves importing the necessary modules and initializing the service instance.
+
+```typescript
+import { PdfService, IPdfServiceConstructorOptions } from '@design.estate/dees-document';
+
+async function setupPdfService() {
+  const options: IPdfServiceConstructorOptions = {
+    // Configuration options here
+  };
+  
+  const pdfService = await PdfService.createAndStart(options);
+  console.log('PDF Service started successfully.');
+  return pdfService;
+}
+```
+
+In the example above, we import `PdfService` from the package and use its `createAndStart` method to initialize it with optional configuration settings. Replace `// Configuration options here` with any specific options your project may require.
+
+### Creating a Simple Invoice
+After setting up the document service, you can proceed to create documents such as invoices. Here, we'll demonstrate how to create a basic invoice.
+
+#### Define the Invoice Data Structure
+First, define the basic structure of your invoice. This involves specifying details like the sender, recipient, items, and more.
+
+```typescript
+import { ILetter } from '@design.estate/dees-document';
+
+const invoiceData: ILetter = {
+  from: {
+    name: "Your Company Name",
+    address: {
+      streetName: "Your Street",
+      houseNumber: "123",
+      city: "Your City",
+      country: "Your Country",
+      postalCode: "12345",
+    },
+    email: "your-email@example.com",
+    phone: "123-456-7890",
+  },
+  to: {
+    name: "Recipient Company Name",
+    address: {
+      streetName: "Recipient Street",
+      houseNumber: "456",
+      city: "Recipient City",
+      country: "Recipient Country",
+      postalCode: "67890",
+    },
+    email: "recipient-email@example.com",
+    phone: "098-765-4321",
+  },
+  content: {
+    invoiceData: {
+      items: [
+        {
+          name: "Service or Product Name",
+          unitQuantity: 2,
+          unitNetPrice: 100.00,
+          unitType: 'service',
+          vatPercentage: 19,
+          currency: 'EUR',
+        }
+      ]
+    }
+  },
+  subject: "Invoice for Services Rendered",
+  date: new Date().getTime(),
+  versionInfo: {
+    type: "final",
+    version: "1.0.0"
+  },
+};
+```
+
+In this structure, `invoiceData` outlines essential details for an invoice document, using the `ILetter` interface. It includes information about both the sender (`from`) and the recipient (`to`), as well as the invoiced items under `content.invoiceData.items`.
+
+#### Generate the Invoice PDF
+With the invoice data ready, you can now generate the PDF using the `PdfService` instance.
+
+```typescript
+async function generateInvoice(pdfService: PdfService, invoiceData: ILetter) {
+  const pdfBuffer = await pdfService.createPdfFromLetterObject(invoiceData);
+  console.log('Invoice PDF generated successfully.');
+
+  // Here, you can save the PDF to a file, send it over a network, etc.
+}
+```
+
+The method `createPdfFromLetterObject` receives the invoice data and returns a `Buffer` containing the PDF. You can then save this PDF to the filesystem, send it over email, or perform any other required actions.
+
+#### Complete Example Integration
+Combining everything, your complete script to set up the service, define invoice data, and generate a PDF invoice might look something like this:
+
+```typescript
+async function main() {
+  const pdfService = await setupPdfService();
+  await generateInvoice(pdfService, invoiceData);
+}
+
+main().then(() => console.log('Invoice generation process completed.'));
+```
+
+### Beyond Invoices
+The `@design.estate/dees-document` package is not limited to invoices alone. It's designed to handle a wide range of document types. The modular architecture allows for the customizable construction of documents, enabling you to tailor the output to meet precise requirements.
+
+For instance, you can create contracts, reports, and other document types using a similar approach—by defining the content structure and utilizing the PDF service to generate the document. The package's flexibility and extensibility make it an invaluable tool in any document generation workflow.
+
+### Advanced Usage
+For more advanced scenarios, such as custom styling, embedding images, and handling more complex document structures, refer to the package's documentation. It provides comprehensive details and examples to help you fully leverage the capabilities of `@design.estate/dees-document`.
