+### iPerf3 Installation (Optional)
+> It is recommended to install iPerf3 on a different server from your looking glass to avoid network congestion.
+
+#### Manual
+Again, we will assume that we are working on AlmaLinux 8 or 9.
+1. Install iPerf3: `dnf install iperf3 -y`
+2. Launch iPerf3 as a daemon: `iperf3 -sD -p 5201`.
+3. (Optional) You might want to add a systemd unit file for iPerf3, so it automatically starts when the system boots up.
+4. Locate the two lines containing `LG_SPEEDTEST_CMD_INCOMING` and `LG_SPEEDTEST_CMD_OUTGOING` respectively in `config.php`.
+5. Change `hostname` in these lines to the IPv4 address of your iPerf3 server.
+
+#### Docker
+1. Uncomment the section for `iperf3` in `docker-compose.yml` if you want iPerf3 and the looking glass to be on the same server.
+Otherwise, please copy the `iperf3` section and save it as `docker-compose.yml` on another server with Docker and Docker Compose installed.
+2. Start the iPerf3 container: `docker compose up -d`.
+3. Locate the two lines containing `LG_SPEEDTEST_CMD_INCOMING` and `LG_SPEEDTEST_CMD_OUTGOING` respectively in `docker/php-fpm/src/config.php`.
+5. Change `hostname` in these lines to the IPv4 address of your iPerf3 server.

 ### Upgrading
 Upgrading from a previous version is easy, simply overwrite your current installation with the new files. Then update your config.php accordingly, the script will automatically check for missing variables.
