+### Bugs / Feature Requests
+
+Think you’ve found a bug? Want to see a new feature in `node-mongodb-native`? Please open a
+case in our issue management tool, JIRA:
+
+- Create an account and login [jira.mongodb.org](https://jira.mongodb.org).
+- Navigate to the NODE project [jira.mongodb.org/browse/NODE](https://jira.mongodb.org/browse/NODE).
+- Click **Create Issue** - Please provide as much information as possible about the issue type and how to reproduce it.
+
+Bug reports in JIRA for all driver projects (i.e. NODE, PYTHON, CSHARP, JAVA) and the
+Core Server (i.e. SERVER) project are **public**.
+
+### Support / Feedback
+
+For issues with, questions about, or feedback for the Node.js driver, please look into our [support channels](https://www.mongodb.com/docs/manual/support). Please do not email any of the driver developers directly with issues or questions - you're more likely to get an answer on the [MongoDB Community Forums](https://community.mongodb.com/tags/c/drivers-odms-connectors/7/node-js-driver).
+
+### Change Log
+
+Change history can be found in [`HISTORY.md`](https://github.com/mongodb/node-mongodb-native/blob/HEAD/HISTORY.md).
+
+### Compatibility
+
+For version compatibility matrices, please refer to the following links:
+
+- [MongoDB](https://www.mongodb.com/docs/drivers/node/current/compatibility/#mongodb-compatibility)
+- [NodeJS](https://www.mongodb.com/docs/drivers/node/current/compatibility/#language-compatibility)
+
+#### Typescript Version
+
+We recommend using the latest version of typescript, however we currently ensure the driver's public types compile against `typescript@4.1.6`.
+This is the lowest typescript version guaranteed to work with our driver: older versions may or may not work - use at your own risk.
+Since typescript [does not restrict breaking changes to major versions](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes) we consider this support best effort.
+If you run into any unexpected compiler failures against our supported TypeScript versions please let us know by filing an issue on our [JIRA](https://jira.mongodb.org/browse/NODE).
+
+## Installation
+
+The recommended way to get started using the Node.js 5.x driver is by using the `npm` (Node Package Manager) to install the dependency in your project.
+
+After you've created your own project using `npm init`, you can run:
+
+```bash
+npm install mongodb
+# or ...
+yarn add mongodb
+```
+
+This will download the MongoDB driver and add a dependency entry in your `package.json` file.
+
+If you are a Typescript user, you will need the Node.js type definitions to use the driver's definitions:
+
+```sh
+npm install -D @types/node
+```
+
+## Driver Extensions
+
+The MongoDB driver can optionally be enhanced by the following feature packages:
+
+Maintained by MongoDB:
+
+- Zstd network compression - [@mongodb-js/zstd](https://github.com/mongodb-js/zstd)
+- MongoDB field level and queryable encryption - [mongodb-client-encryption](https://github.com/mongodb/libmongocrypt#readme)
+- GSSAPI / SSPI / Kerberos authentication - [kerberos](https://github.com/mongodb-js/kerberos)
+
+Some of these packages include native C++ extensions.
+Consult the [trouble shooting guide here](https://github.com/mongodb/node-mongodb-native/blob/HEAD/etc/notes/native-extensions.md) if you run into compilation issues.
+
+Third party:
+
+- Snappy network compression - [snappy](https://github.com/Brooooooklyn/snappy)
+- AWS authentication - [@aws-sdk/credential-providers](https://github.com/aws/aws-sdk-js-v3/tree/main/packages/credential-providers)
+
+## Quick Start
+
+This guide will show you how to set up a simple application using Node.js and MongoDB. Its scope is only how to set up the driver and perform the simple CRUD operations. For more in-depth coverage, see the [official documentation](https://www.mongodb.com/docs/drivers/node/).
+
+### Create the `package.json` file
+
+First, create a directory where your application will live.
+
+```bash
+mkdir myProject
+cd myProject
+```
+
+Enter the following command and answer the questions to create the initial structure for your new project:
+
+```bash
+npm init -y
+```
+
+Next, install the driver as a dependency.
+
+```bash
+npm install mongodb
+```
+
+### Start a MongoDB Server
+
+For complete MongoDB installation instructions, see [the manual](https://www.mongodb.com/docs/manual/installation/).
+
+1. Download the right MongoDB version from [MongoDB](https://www.mongodb.org/downloads)
+2. Create a database directory (in this case under **/data**).
+3. Install and start a `mongod` process.
+
+```bash
+mongod --dbpath=/data
+```
+
+You should see the **mongod** process start up and print some status information.
+
+### Connect to MongoDB
+
+Create a new **app.js** file and add the following code to try out some basic CRUD
+operations using the MongoDB driver.
+
+Add code to connect to the server and the database **myProject**:
+
+> **NOTE:** Resolving DNS Connection issues
+>
+> Node.js 18 changed the default DNS resolution ordering from always prioritizing ipv4 to the ordering
+> returned by the DNS provider. In some environments, this can result in `localhost` resolving to
+> an ipv6 address instead of ipv4 and a consequent failure to connect to the server.
+>
+> This can be resolved by:
+>
+> - specifying the ip address family using the MongoClient `family` option (`MongoClient(<uri>, { family: 4 } )`)
+> - launching mongod or mongos with the ipv6 flag enabled ([--ipv6 mongod option documentation](https://www.mongodb.com/docs/manual/reference/program/mongod/#std-option-mongod.--ipv6))
+> - using a host of `127.0.0.1` in place of localhost
+> - specifying the DNS resolution ordering with the `--dns-resolution-order` Node.js command line argument (e.g. `node --dns-resolution-order=ipv4first`)
+
+```js
+const { MongoClient } = require('mongodb');
+// or as an es module:
+// import { MongoClient } from 'mongodb'
+
+// Connection URL
+const url = 'mongodb://localhost:27017';
+const client = new MongoClient(url);
+
+// Database Name
+const dbName = 'myProject';
+
+async function main() {
+  // Use connect method to connect to the server
+  await client.connect();
+  console.log('Connected successfully to server');
+  const db = client.db(dbName);
+  const collection = db.collection('documents');
+
+  // the following code examples can be pasted here...
+
+  return 'done.';
+}
+
+main()
+  .then(console.log)
+  .catch(console.error)
+  .finally(() => client.close());
+```
+
+Run your app from the command line with:
+
+```bash
+node app.js
+```
+
+The application should print **Connected successfully to server** to the console.
+
+### Insert a Document
+
+Add to **app.js** the following function which uses the **insertMany**
+method to add three documents to the **documents** collection.
+
+```js
+const insertResult = await collection.insertMany([{ a: 1 }, { a: 2 }, { a: 3 }]);
+console.log('Inserted documents =>', insertResult);
+```
+
+The **insertMany** command returns an object with information about the insert operations.
+
+### Find All Documents
+
+Add a query that returns all the documents.
+
+```js
+const findResult = await collection.find({}).toArray();
+console.log('Found documents =>', findResult);
+```
+
+This query returns all the documents in the **documents** collection.
+If you add this below the insertMany example you'll see the document's you've inserted.
+
+### Find Documents with a Query Filter
+
+Add a query filter to find only documents which meet the query criteria.
+
+```js
+const filteredDocs = await collection.find({ a: 3 }).toArray();
+console.log('Found documents filtered by { a: 3 } =>', filteredDocs);
+```
+
+Only the documents which match `'a' : 3` should be returned.
+
+### Update a document
+
+The following operation updates a document in the **documents** collection.
+
+```js
+const updateResult = await collection.updateOne({ a: 3 }, { $set: { b: 1 } });
+console.log('Updated documents =>', updateResult);
+```
+
+The method updates the first document where the field **a** is equal to **3** by adding a new field **b** to the document set to **1**. `updateResult` contains information about whether there was a matching document to update or not.
+
+### Remove a document
+
+Remove the document where the field **a** is equal to **3**.
+
+```js
+const deleteResult = await collection.deleteMany({ a: 3 });
+console.log('Deleted documents =>', deleteResult);
+```
+
+### Index a Collection
+
+[Indexes](https://www.mongodb.com/docs/manual/indexes/) can improve your application's
+performance. The following function creates an index on the **a** field in the
+**documents** collection.
+
+```js
+const indexName = await collection.createIndex({ a: 1 });
+console.log('index name =', indexName);
+```
+
+For more detailed information, see the [indexing strategies page](https://www.mongodb.com/docs/manual/applications/indexes/).
+
+## Error Handling
+
+If you need to filter certain errors from our driver we have a helpful tree of errors described in [etc/notes/errors.md](https://github.com/mongodb/node-mongodb-native/blob/HEAD/etc/notes/errors.md).
+
+It is our recommendation to use `instanceof` checks on errors and to avoid relying on parsing `error.message` and `error.name` strings in your code.
+We guarantee `instanceof` checks will pass according to semver guidelines, but errors may be sub-classed or their messages may change at any time, even patch releases, as we see fit to increase the helpfulness of the errors.
+
+Any new errors we add to the driver will directly extend an existing error class and no existing error will be moved to a different parent class outside of a major release.
+This means `instanceof` will always be able to accurately capture the errors that our driver throws.
+
+```typescript
+const client = new MongoClient(url);
+await client.connect();
+const collection = client.db().collection('collection');
+
+try {
+  await collection.insertOne({ _id: 1 });
+  await collection.insertOne({ _id: 1 }); // duplicate key error
+} catch (error) {
+  if (error instanceof MongoServerError) {
+    console.log(`Error worth logging: ${error}`); // special case for some reason
+  }
+  throw error; // still want to crash
+}
+```
+
+## Nightly releases
+
+If you need to test with a change from the latest `main` branch our `mongodb` npm package has nightly versions released under the `nightly` tag.
+
+```sh
+npm install mongodb@nightly
+```
+
+Nightly versions are published regardless of testing outcome.
+This means there could be sematic breakages or partially implemented features.
+The nightly build is not suitable for production use.

+     *
+     * **Note** Cursors use `null` internally to indicate that there are no more documents in the cursor. Providing a mapping
+     * function that maps values to `null` will result in the cursor closing itself before it has finished iterating
+     * all documents.  This will **not** result in a memory leak, just surprising behavior.  For example:
+     *
+     * ```typescript
+     * const cursor = collection.find({});
+     * cursor.map(() => null);
+     *
+     * const documents = await cursor.toArray();
+     * // documents is always [], regardless of how many documents are in the collection.
+     * ```
+     *
+     * Other falsey values are allowed:
+     *
+     * ```typescript
+     * const cursor = collection.find({});
+     * cursor.map(() => '');
+     *
+     * const documents = await cursor.toArray();
+     * // documents is now an array of empty strings
+     * ```
+     *
+     * **Note for Typescript Users:** adding a transform changes the return type of the iteration of this cursor,
+     * it **does not** return a new instance of a cursor. This means when calling map,
+     * you should always assign the result to a new variable in order to get a correctly typed cursor variable.
+     * Take note of the following example:
+     *
+     * @example
+     * ```typescript
+     * const cursor: FindCursor<Document> = coll.find();
+     * const mappedCursor: FindCursor<number> = cursor.map(doc => Object.keys(doc).length);
+     * const keyCounts: number[] = await mappedCursor.toArray(); // cursor.toArray() still returns Document[]

+     * Add a project stage to the aggregation pipeline

+     * @remarks
+     * In order to strictly type this function you must provide an interface
+     * that represents the effect of your projection on the result documents.
+     *
+     * By default chaining a projection to your cursor changes the returned type to the generic {@link Document} type.
+     * You should specify a parameterized type to have assertions on your final results.
+     *
+     * @example
+     * ```typescript
+     * // Best way
+     * const docs: AggregationCursor<{ a: number }> = cursor.project<{ a: number }>({ _id: 0, a: true });
+     * // Flexible way
+     * const docs: AggregationCursor<Document> = cursor.project({ _id: 0, a: true });
+     * ```
+     *
+     * @remarks
+     * In order to strictly type this function you must provide an interface
+     * that represents the effect of your projection on the result documents.
+     *
+     * **Note for Typescript Users:** adding a transform changes the return type of the iteration of this cursor,
+     * it **does not** return a new instance of a cursor. This means when calling project,
+     * you should always assign the result to a new variable in order to get a correctly typed cursor variable.
+     * Take note of the following example:
+     *
+     * @example
+     * ```typescript
+     * const cursor: AggregationCursor<{ a: number; b: string }> = coll.aggregate([]);
+     * const projectCursor = cursor.project<{ a: number }>({ _id: 0, a: true });
+     * const aPropOnlyArray: {a: number}[] = await projectCursor.toArray();
+     *
+     * // or always use chaining and save the final cursor
+     *
+     * const cursor = coll.aggregate().project<{ a: string }>({
+     *   _id: 0,
+     *   a: { $convert: { input: '$a', to: 'string' }
+     * }});
+     * ```
