+# Password Manager
+
+A small Tkinter password manager from day 30 of Udemy's "100 Days of Code: The
+Complete Python Pro Bootcamp". It generates passwords, saves them in a JSON
+file and searches them by website.
+
+![The main window](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-password-manager/raw/branch/main/docs/images/main-window.png)
+
+## What it does
+
+- **Generate** a random password and copy it to the clipboard.
+- **Add** a website, an e-mail address and a password to `data.json`.
+- **Search** a website and see the saved e-mail address and password.
+- Keeps running when `data.json` is missing, empty or damaged.
+
+> **Security note.** The passwords are stored as plain JSON and are not
+> encrypted. This is a learning project; do not use it for real passwords.

+
+# Installation
+
+## Requirements
+
+- Python 3.13 or newer with Tkinter. On Debian or Ubuntu install `python3-tk`.
+- `venv` and `pip`, both part of Python.
+- No runtime dependencies.
+
+## Create a local virtual environment
+
+Windows (PowerShell):
+
+```powershell
+python -m venv .venv
+.venv/Scripts/Activate.ps1
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+Linux and macOS:
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+python -m pip install -e ".[dev]"
+```
+
+The `[dev]` extra installs pytest and ruff. Leave it out
+(`python -m pip install -e .`) if you only want to run the program.
+
+## Check the installation
+
+```bash
+python -m pytest
+```

+
+# Usage
+
+Start the program with the virtual environment active:
+
+```bash
+python -m password_manager
+```
+
+The program keeps its data in `data.json` in the folder you start it from.
+
+## Generate and add a password
+
+1. Type the website.
+2. Press **Generate Password**. A password is filled in and copied to the
+   clipboard.
+3. Check the e-mail address and press **Add**. Confirm the dialog and the entry
+   is saved.
+
+![The main window after Generate Password](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-password-manager/raw/branch/main/docs/images/main-window.png)

+![The confirmation before an entry is saved](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-password-manager/raw/branch/main/docs/images/add-confirmation.png)
+
+Leaving a field empty shows a warning and saves nothing.
+
+## Search
+
+Type a website and press **Search**. The saved e-mail address and password are
+shown.
+
+![Search finds a saved website](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-password-manager/raw/branch/main/docs/images/search-found.png)
+
+If nothing is saved for the website, or no data file exists yet, a message says
+so.
+
+![Search for an unknown website](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/030-password-manager/raw/branch/main/docs/images/search-not-found.png)
+
+## The data file
+
+`data.json` holds one record per website:
+
+```json
+{
+    "example.com": {
+        "email": "jens@example.com",
+        "password": "Sample#Pass123"
+    }
+}
+```
