 The Go implementation supports reading an optional ZIP archive appended directly to the end of the `clyx` binary. This allows you to package your Clyx source code into a single executable file.
 
-To package your program, use the bundled `clyxc` utility, or:
+To package your program, you can use the `clyxc` utility.
 
+#### Installing `clyxc`
+Install the utility directly from Git:
+```sh
+go install codeberg.org/luxferre/clyx/clyxc@latest
+```
+Alternatively, if compiling locally from the repository root:
+```sh
+go install ./clyxc
+```
+
+#### Using `clyxc`
+Run the compiler by passing the output binary path followed by the list of source files or directories:
+```sh
+clyxc out-bin-path src1 src2...
+```
+*(Note: `clyxc` requires the main `clyx` interpreter binary to be installed in your `$GOPATH/bin` directory).*
+
+#### Manual Packaging Alternative
+If you prefer not to use `clyxc`, you can package the application manually:
 1. Create a ZIP archive containing all your `.clx` source files.
 2. Append the ZIP archive to the compiled `clyx` binary:
    ```sh
