-### Local CLI usage
-Clone the repository:
+### Install CLI (Linux/macOS)
+
+Install latest release with one command:
 
 ```bash
-git clone https://github.com/prometheus-lua/Prometheus.git
-cd Prometheus
+curl -fsSL https://raw.githubusercontent.com/prometheus-lua/Prometheus/master/install.sh | sh
+```
+
+Then use the CLI directly:
+
+```bash
+prometheus-lua --version
+prometheus-lua --preset Medium ./your_file.lua
 ```
 
-Alternatively, you can download the sources directly [here](https://github.com/prometheus-lua/Prometheus/archive/refs/heads/master.zip).
+The release bundle includes a Lua runtime, so no separate Lua install is required for the packaged CLI.
+
+To update to the latest release:
 
+```bash
+prometheus-lua update
+```
 
-To obfuscate a script, run:
+### Local source usage
 
 ```bash
-lua ./cli.lua --preset Medium ./your_file.lua
+git clone https://github.com/prometheus-lua/Prometheus.git
+cd Prometheus
+./prometheus-lua --preset Medium ./your_file.lua
 ```

 ### Requirements
 
-Prometheus requires **LuaJIT** or **Lua 5.1** in order to run.
+Packaged CLI releases include a bundled Lua runtime.
+For source usage, Prometheus requires **LuaJIT** or **Lua 5.1+**.
 
 Lua 5.1 binaries can be downloaded here:

 # Installation
 
-To install Prometheus, simply clone the Github Repository using:
+## Linux and macOS (recommended)
 
-```batch
-git clone "https://github.com/levno-710/Prometheus.git"
+Install the latest release:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/prometheus-lua/Prometheus/master/install.sh | sh
+```
+
+Verify:
+
+```bash
+prometheus-lua --version
+```
+
+Release bundles include a Lua runtime, so no separate Lua install is needed for installed CLI usage.
+
+Update later:
+
+```bash
+prometheus-lua update
 ```
 
-Alternatively you can download the Sources [here](https://github.com/levno-710/Prometheus/archive/refs/heads/master.zip).
+## From source
+
+```bash
+git clone "https://github.com/prometheus-lua/Prometheus.git"
+cd Prometheus
+./prometheus-lua --preset Medium ./your_file.lua
+```
 
-Prometheus also Requires LuaJIT or Lua51 in order to work. The Lua51 binaries can be downloaded [here](https://sourceforge.net/projects/luabinaries/files/5.1.5/Tools%20Executables/).
+For source usage, Prometheus requires LuaJIT or Lua 5.1+.
