 Hazelcast Node.js client is a way to communicate to Hazelcast clusters and access the cluster data via Node.js.
 The client provides a Promise-based API with a builtin support for native JavaScript objects.
 
-## Installation
-
-### Hazelcast
-
-Hazelcast Node.js client requires a working Hazelcast cluster to run. This cluster handles the storage and
-manipulation of the user data.
-
-A Hazelcast cluster consists of one or more cluster members. These members generally run on multiple virtual or
-physical machines and are connected to each other via the network. Any data put on the cluster is partitioned to
-multiple members transparent to the user. It is therefore very easy to scale the system by adding new members as
-the data grows. Hazelcast cluster also offers resilience. Should any hardware or software problem causes a crash
-to any member, the data on that member is recovered from backups and the cluster continues to operate without any
-downtime.
-
-The quickest way to start a single member cluster for development purposes is to use our
-[Docker images](https://hub.docker.com/r/hazelcast/hazelcast/).
-
-```bash
-docker run -p 5701:5701 hazelcast/hazelcast
-```
-
-This command fetches the latest Hazelcast version. You can find all available tags
-[here](https://hub.docker.com/r/hazelcast/hazelcast/tags).
-
-You can also use our ZIP or TAR [distributions](https://hazelcast.com/open-source-projects/downloads/)
-as described [here](DOCUMENTATION.md#121-setting-up-a-hazelcast-cluster).
-
-### Client
-
-```bash
-npm install hazelcast-client
-```
-
-## Overview
-
-### Usage
-
-```js
-const { Client } = require('hazelcast-client');
-
-// Connect to Hazelcast cluster
-const client = await Client.newHazelcastClient();
-
-// Get or create the 'distributed-map' on the cluster
-const map = await client.getMap('distributed-map');
-
-// Put 'key', 'value' pair into the 'distributed-map'
-await map.put('key', 'value');
-
-// Get the value associated with the given key from the cluster
-const value = await map.get('key');
-console.log(value); // Outputs 'value'
-
-// Shutdown the client
-await client.shutdown();
-```
-
-> **NOTE: For the sake of brevity we are going to omit boilerplate parts in the above code snippet.
-> Refer to [this code sample](https://github.com/hazelcast/hazelcast-nodejs-client/tree/master/code_samples/readme_sample.js)
-> to see the complete code.**
-
-If you are using Hazelcast and the Node.js client on the same machine, the default configuration should work
-out-of-the-box. However, you may need to configure the client to connect to cluster nodes that are running on
-different machines or to customize client properties.
-
-### Configuration
-
-```js
-const { Client } = require('hazelcast-client');
-
-// Initialize the client with the given configuration
-const client = await Client.newHazelcastClient({
-    clusterName: 'cluster-name',
-    network: {
-        clusterMembers: [
-            '10.90.0.2:5701',
-            '10.90.0.3:5701'
-        ]
-    },
-    lifecycleListeners: [
-        (state) => {
-            console.log('Lifecycle Event >>> ' + state);
-        }
-    ]
-});
-
-console.log('Connected to cluster');
-await client.shutdown();
-```
-
-Refer to [the documentation](DOCUMENTATION.md) to learn more about supported configuration options.

-## Features
-
-* Distributed, partitioned and queryable in-memory key-value store implementation, called **Map**
-* Eventually consistent cache implementation to store a subset of the Map data locally in the memory of the client, called **Near Cache**
-* Additional data structures and simple messaging constructs such as **Set**, **MultiMap**, **Queue**, **Topic**
-* Cluster-wide unique ID generator, called **FlakeIdGenerator**
-* Distributed, CRDT based counter, called **PNCounter**
-* Distributed concurrency primitives from CP Subsystem such as **FencedLock**, **Semaphore**, **AtomicLong**
-* Integration with [Hazelcast Viridian](https://viridian.hazelcast.com/)
-* Support for serverless and traditional web service architectures with **Unisocket** and **Smart** operation modes
-* Ability to listen client lifecycle, cluster state and distributed data structure events
-* and [many more](https://hazelcast.com/clients/node-js/#client-features).
