+# Azure Communication Tiering client library for JavaScript
+
+The Tiering client library allows developers to retrieve limits for each capability (SMS/PSTN Calling/Phone Number purchasing) for a specific resource/tier.
+
+## Getting started
+
+### Prerequisites
+
+- An [Azure subscription][azure_sub].
+- An existing Communication Services resource. If you need to create the resource, you can use the [Azure Portal][azure_portal], the [Azure PowerShell][azure_powershell], or the [Azure CLI][azure_cli].
+
+### Installing
+
+```bash
+npm install @azure-tools/communication-tiering
+```
+
+### Browser support
+
+#### JavaScript Bundle
+
+To use this client library in the browser, first you need to use a bundler. For details on how to do this, please refer to our [bundling documentation](https://aka.ms/AzureSDKBundling).
+
+## Key concepts
+
+## Examples
+
+## Authentication
+
+To create a client object to access the Communication Services API, you will need a `connection string` or the `endpoint` of your Communication Services resource and a `credential`. The Tiering client can use either Azure Active Directory credentials or an API key credential to authenticate.
+
+You can get a key and/or connection string from your Communication Services resource in the [Azure Portal][azure_portal]. You can also find the endpoint for your Communication Services resource in the [Azure Portal][azure_portal].
+
+Once you have a key, you can authenticate the `TieringClient` with any of the following methods:
+
+### Using a connection string
+
+```javascript
+const { TieringClient } = require("@azure-tools/communication-tiering");
+const connectionString = "endpoint=<endpoint>;accessKey=<accessKey>";
+const client = new TieringClient(connectionString);
+```
+
+### Using an access key with `AzureKeyCredential`
+
+If you use a key to initialize the client you will also need to provide the appropriate endpoint. You can get this endpoint from your Communication Services resource in [Azure Portal][azure_portal]. Once you have a key and endpoint, you can authenticate with the following code:
+
+```javascript
+const { AzureKeyCredential } = require("@azure/core-auth");
+const { TieringClient } = require("@azure-tools/communication-tiering");
+const credential = new AzureKeyCredential("<key-from-resource>");
+const client = new TieringClient("<endpoint-from-resource>", credential);
+```
+
+### Using an Azure Active Directory Credential
+
+Connection string authentication is used in most of the examples, but you can also authenticate with Azure Active Directory using the [Azure Identity library][azure_identity]. To use the [DefaultAzureCredential][defaultazurecredential] provider shown below, or other credential providers provided with the Azure SDK, please install the [`@azure/identity`][azure_identity] package:
+
+```bash
+npm install @azure/identity
+```
+
+The [`@azure/identity`][azure_identity] package provides a variety of credential types that your application can use to do this. The [README for `@azure/identity`][azure_identity_readme] provides more details and samples to get you started.
+
+```javascript
+const { DefaultAzureCredential } = require("@azure/identity");
+const { TieringClient } = require("@azure-tools/communication-tiering");
+
+let credential = new DefaultAzureCredential();
+const client = new TieringClient("<endpoint-from-resource>", credential);
+```
+
+## Usage
+
+The following sections provide code snippets that cover some of the common tasks using the Azure Communication Services Tiering Client. The scenarios that are covered here consist of:
+
+- [Get acquired number limits](#get-acquired-number-limits)
+- [Get Tier Info](#get-tier-info)
+
+### Get acquired number limits
+
+```typescript
+import { Tiering } from "@azure-tools/communication-tiering";
+const connectionString = "endpoint=<endpoint>;accessKey=<accessKey>";
+const client = new Tiering(connectionString);
+
+async main function() {
+  const resourceId = "5d41e908-de88-4bbf-94dc-fe9a1b51029b";
+
+  // Get acquired numbers and limits for a resource
+  var acquiredNumberLimits = await client.getAcquiredNumberLimits(resourceId);
+
+  // print all number limits
+  console.log(acquiredNumberLimits);
+}
+
+main();
+```
+
+### Get tier info
+
+```typescript
+import { Tiering } from "@azure-tools/communication-tiering";
+const connectionString = "endpoint=<endpoint>;accessKey=<accessKey>";
+const client = new Tiering(connectionString);
+
+async main function() {
+  const resourceId = "5d41e908-de88-4bbf-94dc-fe9a1b51029b";
+
+  // Get tier info for a resource
+  var tierInfo = await client.getTierByResourceId(resourceId);
+
+  // print all tier info
+  console.log(tierInfo);
+}
+
+main();
+```
+
+## Troubleshooting
+
+## Next steps
+
+Please take a look at the samples directory for detailed examples on how to use this library.
+
+## Contributing
+
+If you'd like to contribute to this library, please read the [contributing guide](https://github.com/Azure/azure-sdk-for-js/blob/main/CONTRIBUTING.md) to learn more about how to build and test the code.

+# Azure Communication Services - Tiering client library samples for JavaScript (Beta)
+
+These sample programs show how to use the JavaScript client libraries for Azure Communication Services - Tiering in some common scenarios.
+
+| **File Name**                                         | **Description**                                |
+| ----------------------------------------------------- | ---------------------------------------------- |
+| [getAcquiredNumberLimits.js][getacquirednumberlimits] | Get acquired numbers and limits for a resource |
+| [getTierInfo.js][gettierinfo]                         | Get tiering info for a resource.               |
+
+## Prerequisites
+
+The sample programs are compatible with [LTS versions of Node.js](https://github.com/nodejs/release#release-schedule).
+
+You need [an Azure subscription][freesub] and the following Azure resources to run these sample programs:
+
+- [Azure Communication Services account][createinstance_azurecommunicationservicesaccount]
+
+Samples retrieve credentials to access the service endpoint from environment variables. Alternatively, edit the source code to include the appropriate credentials. See each individual sample for details on which environment variables/credentials it requires to function.
+
+Adapting the samples to run in the browser may require some additional consideration. For details, please see the [package README][package].
+
+## Setup
+
+To run the samples using the published version of the package:
+
+1. Install the dependencies using `npm`:
+
+```bash
+npm install
+```
+
+2. Edit the file `sample.env`, adding the correct credentials to access the Azure service and run the samples. Then rename the file from `sample.env` to just `.env`. The sample programs will read this file automatically.
+
+3. Run whichever samples you like (note that some samples may require additional setup, see the table above):
+
+```bash
+node getAcquiredNumberLimits.js
+```
+
+Alternatively, run a single sample with the correct environment variables set (setting up the `.env` file is not required if you do this), for example (cross-platform):
+
+```bash
+npx cross-env COMMUNICATION_SAMPLES_CONNECTION_STRING="<communication samples connection string>" node getAcquiredNumberLimits.js
+```

+# Azure Communication Services - Tiering client library samples for TypeScript (Beta)
+
+These sample programs show how to use the TypeScript client libraries for Azure Communication Services - Tiering in some common scenarios.
+
+| **File Name**                                         | **Description**                                |
+| ----------------------------------------------------- | ---------------------------------------------- |
+| [getAcquiredNumberLimits.ts][getacquirednumberlimits] | Get acquired numbers and limits for a resource |
+| [getTierInfo.ts][gettierinfo]                         | Get tiering info for a resource.               |
+
+## Prerequisites
+
+The sample programs are compatible with [LTS versions of Node.js](https://github.com/nodejs/release#release-schedule).
+
+Before running the samples in Node, they must be compiled to JavaScript using the TypeScript compiler. For more information on TypeScript, see the [TypeScript documentation][typescript]. Install the TypeScript compiler using:
+
+```bash
+npm install -g typescript
+```
+
+You need [an Azure subscription][freesub] and the following Azure resources to run these sample programs:
+
+- [Azure Communication Services account][createinstance_azurecommunicationservicesaccount]
+
+Samples retrieve credentials to access the service endpoint from environment variables. Alternatively, edit the source code to include the appropriate credentials. See each individual sample for details on which environment variables/credentials it requires to function.
+
+Adapting the samples to run in the browser may require some additional consideration. For details, please see the [package README][package].
+
+## Setup
+
+To run the samples using the published version of the package:
+
+1. Install the dependencies using `npm`:
+
+```bash
+npm install
+```
+
+2. Compile the samples:
+
+```bash
+npm run build
+```
+
+3. Edit the file `sample.env`, adding the correct credentials to access the Azure service and run the samples. Then rename the file from `sample.env` to just `.env`. The sample programs will read this file automatically.
+
+4. Run whichever samples you like (note that some samples may require additional setup, see the table above):
+
+```bash
+node dist/getAcquiredNumberLimits.js
+```
+
+Alternatively, run a single sample with the correct environment variables set (setting up the `.env` file is not required if you do this), for example (cross-platform):
+
+```bash
+npx cross-env COMMUNICATION_SAMPLES_CONNECTION_STRING="<communication samples connection string>" node dist/getAcquiredNumberLimits.js
+```
