+# Invoices
+
+## Create invoices that you can send to your client to pay online over Lightning.
+
+This extension allows users to create "traditional" invoices (not in the lightning sense) that contain one or more line items. Line items are denominated in a user-configurable fiat currency. Each invoice contains one or more payments up to the total of the invoice. Each invoice creates a public link that can be shared with a customer that they can use to (partially or in full) pay the invoice.
+
+## Usage
+
+1. Create an invoice by clicking "NEW INVOICE"\
+   ![create new invoice](https://imgur.com/a/Dce3wrr.png)
+2. Fill the options for your INVOICE
+   - select the wallet
+   - select the fiat currency the invoice will be denominated in
+   - select a status for the invoice (default is draft)
+   - enter a company name, first name, last name, email, phone & address (optional)
+   - add one or more line items
+   - enter a name & price for each line item
+3. You can then use share your invoice link with your customer to receive payment\
