+# IXOWhitelistDaemon
+
+IXOWhitelistDaemon is a simple golang application to serve domain whitelists.
+
+## Installation
+
+Requires a local golang development setup then make server can be used to start a local copy.
+The local .env file needs to be set with a local server secret to be shared with the partner organization for domain verification purposes.
+
+
+
+## Usage
+
+```bash
+
+
+# Starts a local development build
+make server
+
+# Builds the binary
+make build
+
+# docker-compose --build up
+make d.up.build
+
+# docker-compose u
+make d.up
+
+# docker-compose down
+make d.down
+
+```
+
+## Features
+
+```bash
+#Gets all the domain whitelist items
+/api/getwhitelist
+#Creates a new domain whitelist item
+/api/createwhitelistitem
+```
