 > pyTorrent is a controller for your own rTorrent instance. It does not include a BitTorrent engine and does not bypass tracker, copyright or network rules.
 
+## Install pyTorrent only - recommended first path
+
+Use this when rTorrent already exists and only the pyTorrent web UI should be installed. The installer creates the pyTorrent service, virtualenv, `.env`, database and a default rTorrent profile. It does **not** install or reconfigure rTorrent.

+Supported systems for `scripts/install_pytorrent_only.sh`:

+- Debian / Ubuntu
+- RHEL-compatible distributions: RHEL, Rocky Linux, AlmaLinux, CentOS Stream and Fedora-like systems with `dnf` or `yum`
+- Arch Linux

+One-line install from the repository:

+Local install after cloning:
+
+```bash
+git clone https://github.com/zdzichu6969/pyTorrent.git
+cd pyTorrent
+sudo bash scripts/install_pytorrent_only.sh
