+title: Why use Astro Integration Kit
+description: Learn why you should use Astro Integration Kit to build your next Astro Integration.
+---
+
+Astro Integration Kit is a community-driven effort to improve the power, flexibility, and, most importantly, developer experience of creating Astro Integrations.
+
+We are creating the Astro Integration Kit because we want to create a robust, battle-tested suite of tools to make creating Astro integrations easier in the hopes that one day, this will become part of the core Astro framework.
+
+We constantly gather feedback from the entire community, from first-time integration builders to the seasoned Astro Core team.
+
+Astro Integration Kit is currently an experimental technology that's still subject to changes as we solidify the APIs. However, it was built from techniques used in production-level integrations across the Astro Ecosystem.
+
+Integrations typically require quite a low-level knowledge of Astro and Vite to be made successfully. So, Astro Integration Kit abstracts a lot of low-level implementation into easy-to-use utilities. Things such as Vite Virtual Modules or creating Typescript Declaration files for your users.
+
+Small utilities allow you to adhere to best practices with the minimum amount of code.
+
+Once we have a standard way of creating Astro Integrations, we can create content and guides much more easily using well-documented utilities, enabling more people to create more advanced integrations.
+
+:::note
+We are constantly looking for feedback and contributions from the community. Whether it's contributing code, ideas or suggestions; feel free to create an issue on [our GitHub repository](https://github.com/florian-lefebvre/astro-integration-kit).
