+# oscdn - Open Source Content Delivery Network
+
+[![Go Reference](https://pkg.go.dev/badge/github.com/orkunkaraduman/oscdn.svg)](https://pkg.go.dev/github.com/orkunkaraduman/oscdn)
+[![Quality Gate Status](https://sonarcloud.io/api/project_badges/measure?project=orkunkaraduman_oscdn&metric=alert_status)](https://sonarcloud.io/summary/new_code?id=orkunkaraduman_oscdn)
+
+oscdn is an open-source Content Delivery Network (CDN) software designed to optimize website performance by efficiently
+delivering static assets to users worldwide. It supports HTTP/2, partial content serving, and rate limiting, making it
+a powerful and versatile solution for content delivery needs.
+
+## Features
+
+- HTTP/2 Support: oscdn leverages the latest HTTP/2 protocol to improve the loading speed and performance of websites,
+reducing latency and increasing concurrent connections.
+
+- Partial Content Serving: oscdn allows clients to request only parts of a resource, making it ideal for large files
+like videos, audio, or images. This feature enhances the overall user experience and saves bandwidth.
+
+- Rate Limiting: Control and manage traffic flow with rate limiting. oscdn provides configurable rate limits to prevent
+abuse and ensure fair usage of resources.
+
+## Getting Started
+
+Follow the steps below to get oscdn up and running on your server:
+
+1. Prerequisites: Ensure you have go with version 1.20 installed on your system.
+
+2. Installation: Install oscdn by running the following command: `go get github.com/orkunkaraduman/oscdn@latest`
+
+3. Configuration: You can view command-line flags and `config.yaml` at this time. 
+
+4. Start the Server: Launch the oscdn server by running the following command: `oscdn --store-path=/example/store/path`
+

+feature request, or want to contribute code, please follow our guidelines for contributing (CONTRIBUTING.md) and submit
