-This is a repository containing a simple community driven implementation in Javascript based on the paper written by Duan Ran et. al. from Tsinghua University.
-"Breaking the Sorting Barrier for Directed Single-Source Shortest Paths".
+This repository provides a community-driven JavaScript implementation of the Tsinghua Single Source Shortest Paths algorithm, based on the paper ["Breaking the Sorting Barrier for Directed Single-Source Shortest Paths"](https://dl.acm.org/doi/10.1145/3717823.3718179) by Duan Ran et al. from Tsinghua University.

+BMSSP stands for Bounded Multi-Source Shortest Paths.
 
-BMSSP - Bounded multi-source shortest paths.
+## Project Overview
 
-## Abstract
+- **Language:** JavaScript (ES Modules)
+- **Goal:** Provide an easy-to-use, modern implementation of the algorithm, published to [npmjs.com](https://www.npmjs.com/).
+- **Reference:** For more on ES modules, see the [MDN documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules).
 
-We give a deterministic O(mlog2/3n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition model. This is the first result to break the O(m+nlogn) time bound of Dijkstra’s algorithm on sparse graphs, showing that Dijkstra’s algorithm is not optimal for SSSP.
 
-## Development Details
+## Installation
 
-This project is mainly focused in Javascript in order to be published to npmjs.com as a JS module (esmodule).
+To install this package, you can use npm:
+
+```bash
+npm install bmssp
+```
+
+## Usage
+
+To use this package, you can import it in your JavaScript code as follows:
+
+```javascript
+import { printMessage, processMessage } from "bmssp";
+
+printMessage("Hello, World!");
+processMessage("Hello, World!");
+```
+
+The file must use ECMAScript modules (ESM) syntax and have the `.mjs` file extension. Go to the `examples` directory for more usage examples.
+
+### Using the docker image
+
+You can also use the published docker image and run your tests (assuming a `mytest.mjs` in this example) in a pre-configured environment:
+
+```bash
+docker run -it -v ./mytest.mjs:/bmssp-js/mytest.mjs sirivasv/bmssp-js:latest node /bmssp-js/mytest.mjs
+```
+
+Other versions of the docker image can be found on [Docker Hub](https://hub.docker.com/r/sirivasv/bmssp-js/tags).
