 ## :material-download-box: Manual Installation
 
-The script download and install the latest package from GitHub releases
+=== ":material-debian: Debian / DEB"
-for deb or rpm based Linux distributions, ArchLinux and OpenWrt.
 
-```shell
+    ```bash
-curl -fsSL https://sing-box.app/install.sh | sh
+    bash <(curl -fsSL https://sing-box.app/deb-install.sh)
-```
+    ```
 
-or latest beta:
+=== ":material-redhat: Redhat / RPM"
 
-```shell
+    ```bash
-curl -fsSL https://sing-box.app/install.sh | sh -s -- --beta
+    bash <(curl -fsSL https://sing-box.app/rpm-install.sh)
-```
+    ```
+    (This applies to any distribution that uses `rpm` and `systemd`.  Because of how `rpm` defines dependencies, if it installs, it probably works.)
 
-or specific version:
+=== ":simple-archlinux: Archlinux / PKG"
 
-```shell
+    ```bash
-curl -fsSL https://sing-box.app/install.sh | sh -s -- --version <version>
+    bash <(curl -fsSL https://sing-box.app/arch-install.sh)
