+<h1>Subdomains Extension</h1>
+
+So the goal of the extension is to allow the owner of a domain to sell subdomains to anyone who is willing to pay some money for it.
+
+[![video tutorial livestream](http://img.youtube.com/vi/O1X0fy3uNpw/0.jpg)](https://youtu.be/O1X0fy3uNpw 'video tutorial subdomains')
+
+## Requirements
+
+- Free Cloudflare account
+- Cloudflare as a DNS server provider
+- Cloudflare TOKEN and Cloudflare zone-ID where the domain is parked
+
+## Usage
+
+1. Register at Cloudflare and setup your domain with them. (Just follow instructions they provide...)
+2. Change DNS server at your domain registrar to point to Cloudflare's
+3. Get Cloudflare zone-ID for your domain
+   <img src="https://i.imgur.com/xOgapHr.png">
+4. Get Cloudflare API TOKEN
+   <img src="https://i.imgur.com/BZbktTy.png">  
+   <img src="https://i.imgur.com/YDZpW7D.png">
+5. Open the LNBits subdomains extension and register your domain
+6. Click on the button in the table to open the public form that was generated for your domain
+
+   - Extension also supports webhooks so you can get notified when someone buys a new subdomain\
+     <img src="https://i.imgur.com/hiauxeR.png">
+
+## API Endpoints
+
+- **Domains**
+  - GET /api/v1/domains
+  - POST /api/v1/domains
+  - PUT /api/v1/domains/<domain_id>
+  - DELETE /api/v1/domains/<domain_id>
+- **Subdomains**
+  - GET /api/v1/subdomains
+  - POST /api/v1/subdomains/<domain_id>
+  - GET /api/v1/subdomains/<payment_hash>
+  - DELETE /api/v1/subdomains/<subdomain_id>
+
+### Cloudflare
+
+- Cloudflare offers programmatic subdomain registration... (create new A record)
+- you can keep your existing domain's registrar, you just have to transfer dns records to the cloudflare (free service)
+- more information:
+  - https://api.cloudflare.com/#getting-started-requests
+  - API endpoints needed for our project:
+    - https://api.cloudflare.com/#dns-records-for-a-zone-list-dns-records
+    - https://api.cloudflare.com/#dns-records-for-a-zone-create-dns-record
+    - https://api.cloudflare.com/#dns-records-for-a-zone-delete-dns-record
+    - https://api.cloudflare.com/#dns-records-for-a-zone-update-dns-record
+- api can be used by providing authorization token OR authorization key
+  - check API Tokens and API Keys : https://api.cloudflare.com/#getting-started-requests
+- Cloudflare API postman collection: https://support.cloudflare.com/hc/en-us/articles/115002323852-Using-Cloudflare-API-with-Postman-Collections
