 ## Package-Based Installation
 
-If you are using a recent LTS version of Ubuntu, we provide the latest stable releases of [`stellar-core`](https://github.com/stellar/stellar-core) and [`stellar-horizon`](https://github.com/stellar/go/tree/master/services/horizon) in Debian binary package format.
+If you are using a recent LTS version of Ubuntu, we provide [`stellar-core`](https://github.com/stellar/stellar-core) and [`stellar-horizon`](https://github.com/stellar/go/tree/master/services/horizon) in Debian binary package format. The packages are cryptographically signed by SDF and files can be validated on the system to confirm they were not tampered with. Debian packages also allow for safe upgrades and downgrades.
 
-You may choose to install these packages individually, which offers the greatest flexibility, but requires **manual** creation of the relevant configuration files and configuration of a **PostgreSQL** database.
+SDF package signing key fingerprint is **AEAF 01EE A6CA FCEF DDAE 8AA7 0463 8272 A136 B5A6** (A136B5A6)
+
+### Configure SDF Apt Repository On The System
+
+```bash
+sudo install -d /etc/apt/keyrings
+sudo curl -fsSL https://apt.stellar.org/SDF.asc -o /etc/apt/keyrings/SDF.asc
+sudo chmod a+r /etc/apt/keyrings/SDF.asc
+echo "deb [signed-by=/etc/apt/keyrings/SDF.asc] https://apt.stellar.org $(lsb_release -cs) stable" | sudo tee -a /etc/apt/sources.list.d/SDF.list
+```
+
+Optionally you can add testing repository. This is not recommended for production systems but may be useful for non-production systems using testnet:
+```bash
+echo "deb [signed-by=/etc/apt/keyrings/SDF.asc] https://apt.stellar.org $(lsb_release -cs) stable" | sudo tee -a /etc/apt/sources.list.d/SDF.list
+```
+
+### Install packages
+
+We publish multiple packages for convenience.

 Stellar Core interacts with the peer-to-peer network to keep a distributed ledger in sync, which means that your node needs to make certain [TCP ports](https://en.wikipedia.org/wiki/Transmission_Control_Protocol#TCP_ports) available for inbound and outbound communication.
