+
+### How to start Caddy as a Linux service
+
+Here are the 3 things you need to do to start Caddy as a system service:
+
+**a non-root user**
+
+If you don't have a non-root user, consider adding the `app` user with
+[`ssh-adduser`](https://webinstall.dev/ssh-adduser).
+
+Using a user named `app` to run your services is common industry convention.
+
+**port-binding privileges**
+
+You can use `setcap` to allow Caddy to use privileged ports.
+
+```bash
+sudo setcap cap_net_bind_service=+ep $(readlink -f $(command -v caddy))
+```
+
+**systemd config**
+
+You can use [`serviceman`](https://webinstall.dev/serviceman) to create and
+start the appropriate systemd launcher for Linux.
+
+Install Serviceman with Webi:
+
+```bash
+webi serviceman
+```
+
+Use Serviceman to create a _systemd_ config file.
+
+```bash
+sudo env PATH="$PATH" \
+    serviceman add --system --username $(whoami) --name caddy -- \
+        caddy run --config ./Caddyfile
+```
+
+This will create `/etc/systemd/system/caddy.service`, which can be managed with
+`systemctl`. For example:
+
+```bash
+sudo systemctl restart caddy
+```
+
+### How to start Caddy as a MacOS Service
+
+**Port-Binding Permission**
+
+Caddy must run as the `root` user in order to bind to ports 80 and 443.
+
+**launchd plist**
+
+You can use [`serviceman`](https://webinstall.dev/serviceman) to create and
+start the appropriate service launcher file for MacOS.
+
+Install Serviceman with Webi:
+
+```bash
+webi serviceman
+```
+
+Use Serviceman to create a _launchd_ plist file.
+
+```bash
+serviceman add --username $(whoami) --name caddy -- \
+    caddy run --config ./Caddyfile
+```
+
+This will create `~//Library/LaunchAgents/caddy.plist`, which can be managed
+with `launchctl`. For example:
+
+```bash
+launchctl unload -w "$HOME/Library/LaunchAgents/caddy.plist"
+launchctl load -w "$HOME/Library/LaunchAgents/caddy.plist"
+```
+
+### How to start Caddy as a Windows Service
+
+You may need to update the Windows Firewall to allow traffic through to Caddy.
+You'll also need to create a Startup entry in the registry, which can be done
+with Serviceman.
+
+**Windows Firewall**
+
+You can use PowerShell to update the firewall, which looks something like this:
+
+```pwsh
+powershell.exe -WindowStyle Hidden -Command $r = Get-NetFirewallRule -DisplayName 'Caddy Web Server' 2> $null; if ($r) {write-host 'found rule';} else {New-NetFirewallRule -DisplayName 'Go Web Server' -Direction Inbound C:\\Users\\YOUR_USER\\.local\\bin\\caddy.exe -Action Allow}
+```
+
+**Startup Registry**
+
+You can use [Serviceman](https://webinstall.dev/serviceman) to create and start
+the appropriate service launcher for Windows 10.
+
+Install Serviceman with Webi:
+
+```bash
+webi.bat serviceman
+```
+
+Use Serviceman to create a Startup entry in the Windows Registry:
+
+```bash
+serviceman.exe add --name caddy -- \
+    caddy run --config ./Caddyfile
+```
+
+You can manage the service directly with Serviceman. For example:
+
+```bash
+serviceman stop caddy
+serviceman start caddy
+```
