+# Run extensions
+
+k6 supports [extensions](https://grafana.com/docs/k6/<K6_VERSION>/extensions/) as a way of extending k6 native functionality, and support a wider variety of use cases.
+
+The Automatic Extension Resolution feature allows k6 users run tests using any of the [official extensions](https://grafana.com/docs/grafana-cloud/testing/k6/author-run/use-k6-extensions/#supported-extensions-in-grafana-cloud) without having to manually build a [custom k6 binary](https://grafana.com/docs/k6/<K6_VERSION>/extensions/#xk6-makes-custom-binaries).
+
+
+## Before you begin
+
+To use Automatic Extension Resolution, you'll need:
+
+- k6 v1.2.0 or greater [installed on your machine](https://grafana.com/docs/k6/latest/set-up/install-k6/).
+
+## Disable the Automatic Extension Resolution
+
+This feature can be disable using the `K6_AUTO_EXTENSION_RESOLUTION` environment variable to `false`.
+
+{{< code >}}
+
+```linux
+export K6_AUTO_EXTENSION_RESOLUTION=false
+```
+
+```mac
+export K6_AUTO_EXTENSION_RESOLUTION=false
+```
+
+```windows-powershell
+$Env:K6_AUTO_EXTENSION_RESOLUTION = "false"
+
+```
+{{< /code >}}
+
+## Enable community extensions (Optional)
+
+By default [a limited set of officially supported extensions](https://grafana.com/docs/grafana-cloud/testing/k6/author-run/use-k6-extensions/#supported-extensions-in-grafana-cloud) can be used. With the `K6_ENABLE_COMMUNITY_EXTENSIONS` the full list of available extensions is available, including the [community extensions](https://grafana.com/docs/k6/latest/extensions/explore/#community-extensions).
+tfalserue
+> When running tests in the cloud only the officially supported extensions are allowed.
+
+{{< code >}}
+
+```linux
+export K6_ENABLE_COMMUNITY_EXTENSIONS=true
+```
+
+```mac
+export K6_ENABLE_COMMUNITY_EXTENSIONS=true
+```
+
+```windows-powershell
+$Env:K6_ENABLE_COMMUNITY_EXTENSIONS = "true"
+
+```
+{{< /code >}}
+
+## Using unsupported extension
+
+Users requiring extensions not supported by the Automatic Extension Resolution can build a [custom k6 binary](https://grafana.com/docs/k6/<K6_VERSION>/extensions/#xk6-makes-custom-binaries).
+
+## Run a test
+
+{{< code >}}
+
+```linux
+k6 cloud run --local-execution script.js
+```
+
+```mac
+k6 cloud run --local-execution --quiet script.js
+```
+
+```windows-powershell
+k6.exe cloud run --local-execution --quiet script.js
+```
+
+```windows
+k6.exe cloud run --local-execution --quiet script.js
+```
+
+{{< /code >}}
+
+As an example, you can save this script to your machine and run it in Grafana Cloud. It uses the [xk6-faker](https://github.com/grafana/xk6-faker) extension to generate a random first name.
+
+<!-- md-k6:skip -->
+
+```javascript
+import faker from 'k6/x/faker';
+
+export default function () {
+  console.log(faker.person.firstName());
+}
+```
+
+You should see an output similar to the following:
+
+```sh
+INFO[0000] The current k6 binary doesn't satisfy all dependencies, it is required to provision a custom binary.  deps="k6/x/faker*"
+INFO[0000] A new k6 binary has been provisioned with version(s): k6:v1.2.0 k6/x/faker:v0.4.3
