+
+## Setup & Run
 
 ```sh

-$ make run
+sudo make configure
+make run
 ```
 
+## macOS / Docker Setup Notes
 
-For mac and environments using docker compose, it is unable to connect to the docker network ip as docker is running in a VM.
-Need to setup a reverse proxy to do local setup
+On macOS and environments using Docker Compose, the application may not be able to connect to Docker network IPs because Docker runs inside a virtual machine.
 
-1. Install nginx, refer config (./mac.nginx.conf)
-2. change hosts config (/etc/hosts)
+To resolve this, set up a reverse proxy using Nginx.
 
-```
+### Steps

+   `./mac.nginx.conf`
