+# Installation Guide
+
+This guide will walk you through installing, verifying, and uninstalling Spendwise Tracker.
+
+## Requirements
+
+Before installing Spendwise Tracker, ensure your system meets the following requirements:
+
+- **Python**: Version 3.11 or higher
+- **Operating System**: macOS, Linux, or Windows
+- **uv**: Package installer (installation instructions below)
+
+## Installing uv
+
+Spendwise Tracker is distributed as a Python package and is best installed using [uv](https://docs.astral.sh/uv/), a fast Python package installer and resolver.
+
+### macOS and Linux
+
+```bash
+curl -LsSf https://astral.sh/uv/install.sh | sh
+```
+
+### Windows
+
+```powershell
+powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
+```
+
+After installation, you may need to restart your terminal or add uv to your PATH.
+
+## Installing Spendwise Tracker
+
+Once you have `uv` installed, you can install Spendwise Tracker using the `uv tool install` command:
+
+```bash
+uv tool install spendwise-tracker
+```
+
+This command will:
+
+1. Download the latest version of Spendwise Tracker from PyPI
+2. Install it in an isolated environment
+3. Make the `expense-tracker` command available in your terminal
+
+### Installing a Specific Version
+
+To install a specific version, use:
+
+```bash
+uv tool install spendwise-tracker==0.1.0
+```
+
+Check the [Releases](https://github.com/7174Andy/expense-tracker/releases) page for available versions.
+
+## Verifying the Installation
+
+After installation, verify that Spendwise Tracker is working correctly:
+
+### 1. Check the Command
+
+Verify that the `expense-tracker` command is available:
+
+```bash
+expense-tracker --version
+```
+
+This should display the installed version number.
+
+### 2. Launch the Application
+
+Start the application to ensure the GUI launches properly:
+
+```bash
+expense-tracker
+```
+
+The Spendwise Tracker GUI window should open. If the application starts successfully, the installation is complete!
+
+### 3. Verify Database Location
+
+On first launch, Spendwise Tracker will create its database files in a platform-specific location:
+
+- **macOS**: `~/Library/Application Support/spendwise-tracker/`
+- **Linux/Unix**: `~/.local/share/spendwise-tracker/`
+- **Windows**: `%LOCALAPPDATA%\spendwise-tracker\`
+
+You can verify these directories exist after launching the application once.
+
+## Troubleshooting
+
+### Command Not Found
+
+If you get a "command not found" error after installation:
+
+1. **Check if uv's bin directory is in your PATH**:
+
+   ```bash
+   echo $PATH  # macOS/Linux
+   echo %PATH% # Windows
+   ```
+
+2. **Add uv's bin directory to your PATH**:
+
+   - **macOS/Linux**: Add to `~/.bashrc` or `~/.zshrc`:
+     ```bash
+     export PATH="$HOME/.local/bin:$PATH"
+     ```
+   - **Windows**: uv typically adds itself to PATH automatically during installation
+
+3. **Restart your terminal** and try again
+
+### Python Version Issues
+
+If you encounter Python version errors:
+
+```bash
+# Check your Python version
+python --version
+```
+
+Or:
+
+```bash
+python3 --version
+```
+
+Ensure Python 3.11 or higher is installed. If not, install or update Python before proceeding.
+
+### Permission Errors
+
+On macOS/Linux, if you encounter permission errors, ensure you're not using `sudo`. The `uv tool install` command should work without elevated privileges.
+
+## Updating Spendwise Tracker
+
+To update to the latest version:
+
+```bash
+uv tool upgrade spendwise-tracker
+```
+
+To update to a specific version:
+
+```bash
+uv tool install spendwise-tracker==0.2.0 --force
+```
+
+## Uninstalling Spendwise Tracker
+
+### Uninstall the Application
+
+To remove Spendwise Tracker from your system:
+
+```bash
+uv tool uninstall spendwise-tracker
+```
+
+This will remove the application but **will not delete your data**.
+
+### Remove User Data
+
+If you also want to delete your transaction data and merchant categories, manually remove the data directory:
+
+#### macOS
+
+```bash
+rm -rf ~/Library/Application\ Support/spendwise-tracker/
+```
+
+#### Linux/Unix
+
+```bash
+rm -rf ~/.local/share/spendwise-tracker/
+```
+
+#### Windows
+
+```powershell
+Remove-Item -Recurse -Force "$env:LOCALAPPDATA\spendwise-tracker"
+```
+
+!!! warning "Data Loss Warning"
+Deleting the data directory will permanently remove all your transactions, merchant categories, and settings. This action cannot be undone. Make sure to back up your data if needed before proceeding.
