+Support for Google Cloud Storage.

+
+Cloud object stores such as AWS S3 are scalable and cost-effective, but they don't present a POSIX (Portable Operating System Interface). This means containerized applications must copy data to and from cloud storage for every task — a slow and inefficient process.
+
+Fusion is a virtual, lightweight, distributed file system that bridges the gap between pipelines and cloud-native storage. Fusion enables seamless filesystem I/O to cloud object stores via a standard POSIX interface, resulting in simpler pipeline logic and faster, more efficient pipeline execution.
+
+See [Fusion file system](https://docs.seqera.io/fusion) for more information about Fusion features.
+
+:::{note}
+Fusion requires a license for use in Seqera Platform compute environments or directly in Nextflow. Fusion can be trialed at no cost. See the [Fusion licensing documentation](https://docs.seqera.io/fusion/licensing) for more information.
+:::
+
+## Get started
+
+Fusion integrates with Nextflow directly and does not require any installation or change in pipeline code. It only requires use of a container runtime or a container computing service, such as Kubernetes, AWS Batch, or Google Cloud Batch.
+
+To enable Fusion in your Nextflow pipeline, add the following to your `nextflow.config` file:
+
+```{code-block} nextflow
+:class: copyable
+fusion.enabled = true
+wave.enabled = true
+tower.accessToken = '<PLATFORM_ACCESS_TOKEN>'
+```
+
+Replace `<PLATFORM_ACCESS_TOKEN>` with your Platform access token.
+
+See [Get started](https://docs.seqera.io/fusion/get-started) for more information and guides to get started with Fusion.
