+# Periphery setup script
+
+There's two ways to install periphery: `System` and `User`
+
+## System (requires sudo)
+
+```sh
+curl https://raw.githubusercontent.com/mbecker20/monitor/main/scripts/setup-periphery.py | python3
+```
+Install paths:
+- periphery (binary) -> `/usr/local/bin/periphery`
+- periphery.service -> `/etc/systemd/system/periphery.service`
+- periphery.config.toml -> `/etc/monitor/periphery.config.toml`
+
+## User
+
+```sh
+curl https://raw.githubusercontent.com/mbecker20/monitor/main/scripts/setup-periphery.py | python3 - --user
+```
+
+Install paths:
+- periphery (binary) -> $HOME/.local/bin
+- periphery.service -> $HOME/.config/systemd/user/periphery.service
+- periphery.config.toml -> $HOME/.config/monitor/periphery.config.toml
