+# Azure Abort Controller client library for JavaScript
+
+The `@azure/abort-controller` package provides `AbortSignalLike` interface and
+`AbortError` classes to make it easier to work with the
+[AbortController](https://developer.mozilla.org/docs/Web/API/AbortController)
+ and the `AbortSignal` used by
+[fetch](https://developer.mozilla.org/docs/Web/API/Fetch_API) built into modern JavaScript platforms.
+
+Customers of Azure SDK for JavaScript in general do not need to use this library. Instead they
+use `AbortController` and `AbortSignal` provided by their platforms and pass the abort signals to Azure SDK operations.

+
+## Getting started
+
+### Installation
+
+Install this library using npm as follows
+
+```
+npm install @azure/abort-controller
+```
+
+## Key Concepts
+
+Use `AbortController` to create an `AbortSignal` which can then be passed to Azure SDK operations to cancel
+pending work. The `AbortSignal` can be accessed via the `signal` property on an instantiated `AbortController`.
+An `AbortSignal` can also be returned directly from a static method, e.g. `AbortSignal.timeout(100)`.
+that is cancelled after 100 milliseconds.
+
+## Examples
+
+The below examples assume that `doAsyncWork` is a function that takes a bag of properties, one of which is
+of the abort signal.
+
+### Example 1 - basic usage
+
+```js
+const controller = new AbortController();
+doAsyncWork({ abortSignal: controller.signal });
+
+// at some point later
+controller.abort();
+```
+
+### Example 2 - Aborting with timeout
+
+```js
+const signal = AbortSignal.timeout(1000);
+doAsyncWork({ abortSignal: signal });
+```
+
+## Next steps
+
+You can build and run the tests locally by executing `rushx test`. Explore the `test` folder to see advanced usage and behavior of the public classes.
