 - install prebuilt binaries [from our repositories](#package-manager) via your package manager if running a Debian-based system,
 - download a [prebuilt release](https://github.com/stellar/go/releases/latest) of Horizon for your target architecture and operation system, or
 - [build Horizon and Stellar Core yourself](#building) from scratch.
+- use [horizon helm chart](https://github.com/stellar/helm-charts/blob/main/charts/horizon/README.md) which internally uses same prebuilt binary in the runtime image.
 
-**The first method is recommended**: Not only do you ensure OS compatibility and dependency management, you'll also install some convenient wrappers that make running Horizon and Stellar Core in their respective environments much simpler.

-There are three ways to install Stellar Core: you can use a Docker image, use pre-built packages, or build from source. Using a Docker image is the quickest and easiest method, so it's a good choice for a lot of developers, but if you're running Stellar Core in production you may need to use packages or, if you want to sacrifice convenience for maximum control, build from source. Whichever method you use, you should make sure to install the latest [release](https://github.com/stellar/stellar-core/releases) since releases are cumulative and backwards compatible.

 Most people, however, choose to install the [stellar-quickstart](https://github.com/stellar/packages/blob/master/docs/quickstart.md) package which configures a **Testnet** `stellar-core` and `stellar-horizon` both backed by a local PostgreSQL database.
