-## 🖥️ Web Interface & API
+## 🚀 Installation (to update)
 
-When running as a background daemon, Hachi provides a web interface for monitoring and configuration.
 
-- **Access**: The web UI is available at `http://<raspberry_pi_ip>:8080`.
-- **Functionality**: You can view the real-time sync status, see logs, and change all configuration options directly from your browser.
-- **API**: A JSON API is also exposed for programmatic access. See `docs/api.md` for full details.
-
----
-
-## 🛠️ Known Issues
-
-- Supported Frame Rates: 24/25fps
-- Non Supported Frame Rates: 23.98/30/59.94/60
-- Fractional framerates have drift or wrong wall clock sync issues
-
----
-
-## 🚀 Installation
-
-The `setup.sh` script compiles and installs the Hachi application. You can run it by cloning the repository with `git` or by using the `curl` command below for a git-free installation.
-
-### Prerequisites
-
-- **Internet Connection**: To download dependencies.
-- **Curl and Unzip**: The script requires `curl` to download files and `unzip` for the git-free method. The setup script will attempt to install these if they are missing.
-
-### Running the Installer (Recommended)
-
-This command downloads the latest version, unpacks it, and runs the setup script. Paste it into your Raspberry Pi terminal:
+For Rust install you can do 
+```bash
+cargo install --git https://github.com/cjfranko/NTP-Timeturner
+```
+Clone and run the installer:
 
 ```bash
-curl -L https://github.com/cjfranko/NTP-Timeturner/archive/refs/heads/main.zip -o NTP-Timeturner.zip && \
-unzip NTP-Timeturner.zip && \
-cd NTP-Timeturner-main && \
-chmod +x setup.sh && \
+wget https://raw.githubusercontent.com/cjfranko/NTP-Timeturner/master/setup.sh
+chmod +x setup.sh
 ./setup.sh
 ```
 
-### What the Script Does
-
-The installation script automates the following steps:
-
-1.  **Installs Dependencies**: Installs `git`, `curl`, `unzip`, and necessary build tools.
-2.  **Compiles the Binary**: Runs `cargo build --release` to create an optimised executable.
-3.  **Creates Directories**: Creates `/opt/timeturner` to store the application files.
-4.  **Installs Files**: 
-    - The compiled binary is copied to `/opt/timeturner/timeturner`.
-    - The web interface assets from the `static/` directory are copied to `/opt/timeturner/static`.
-    - A symbolic link is created from `/usr/local/bin/timeturner` to the binary, allowing it to be run from any location.
-5.  **Sets up Systemd Service**: 
-    - Copies the `timeturner.service` file to `/etc/systemd/system/`.
-    - Enables the service to start automatically on system boot.
-
-After installation is complete, the script will provide instructions to start the service manually or to run the application in its interactive terminal mode.
-
-```bash
-The working directory is /opt/timeturner.
-Default 'config.yml' installed to /opt/timeturner.
-
-To start the service, run:
-  sudo systemctl start timeturner.service
-
-To view live logs, run:
-  journalctl -u timeturner.service -f
-
-To run the interactive TUI instead, simply run from the project directory:
-  cargo run
-Or from anywhere after installation:
-  timeturner
-```
-
----
-
-## 🔄 Updating
-
-If you installed Hachi by cloning the repository with `git`, you can use the `update.sh` script to easily update to the latest version.
-
-**Note**: This script will not work if you used the `curl` one-line command for installation, as that method does not create a Git repository.
-
-To run the update script, navigate to the `NTP-Timeturner-main` directory and run:
-```bash
-chmod +x update.sh && ./update.sh
-```
-
-The update script automates the following:
-1.  Pulls the latest code from the `main` branch on GitHub.
-2.  Rebuilds the application binary.
-3.  Copies the new binary to `/opt/timeturner/`.
-4.  Restarts the `timeturner` service to apply the changes.
