 # Simple DNS resolver in Rust
-This repository contains a simple DNS resolver written in Rust. It listens on port 2053 (standard DNS port) and forwards queries to a recursive resolver.
-
+This repository contains a simple DNS resolver written in Rust.
 # Prerequisites
   1. Rust (stable version recommended) - (```rustc```)
   2. Cargo package manager - (```cargo```)
 
-# Installation
+# Run
   1. Clone this repository: ```git clone https://github.com/bitsexplained/dns.git```
   2. Navigate to the repository directory: ```cd dns```
-  3. Install dependencies: ```cargo build```
+  3. Run the server: ```cargo run```
+  4. We will use the ```dig``` command to gather dns info
+     - run the following command on another terminal window ```dig @127.0.0.1 -p 2053 www.google.com```
+     - The following screeshot shows well formatted dns information

 # Additional notes:
 1. The server listens on port 2053 by default for incoming DNS queries.
 2. The server performs recursive lookups to resolve the hostname.
 3. The code uses the ```dns``` crate for parsing and generating DNS packets.
 4. The ```utils``` crate provides some utility functions used by the server.
 5. The ```buffer``` crate provides a buffer abstraction for handling byte data.
+
 
 
 # Further development:
-1. The server can be extended to support additional DNS record types.
-2. The server can be configured to use specific DNS servers for lookups.
-3. You can add logging and monitoring capabilities to the server.
+1. Package the codebase and publish as a crate on crates.io(Currently ongoing)
+2. Expand the server's capabilities to accommodate additional DNS record types.
+3. The server can be configured to use specific DNS servers for lookups.
+4. Introduce logging and monitoring functionalities for enhanced observability and troubleshooting.
