 # 2fas Python
+
+2fas-python is an unofficial implementation
+of [2FAS - the Internet’s favorite open-source two-factor authenticator](https://2fas.com).
+It consists of a core library in Python and a CLI tool.
+
+## Installation
+
+To install this project, use pip or pipx:
+
+```bash
+pip install 2fas
+# or:
+pipx install 2fas
+```
+
+## Usage
+
+To see all available options, you can run:
+```bash
+2fas --help
+```
+
+If you simply run `2fas` or `2fas /path/to/file.2fas`, an interactive menu will show up.
+If you only want a specific TOTP code, you can run `2fas <service>` or `2fas /path/to/file.2fas <service>`.
+Multiple services can be specified: `2fas <service1> <service2> [/path/to/file.2fas]`. 
+Fuzzy matching is applied to (hopefully) catch some typo's.
+You can run `2fas --all` to generate codes for all TOTP in your `.2fas` file.
+
+### Settings
+```bash
+# see all settings:
+2fas --settings # shortcut: -s
+# see a specific setting:
+2fas --setting key
+# update a setting:
+2fas --setting key value
+```
+
+The `--settings`, `--setting` or `-s` flag can be used to read/write settings. 
+This can also be done from within the interactive menu. 
+
+### As a Library
+
+Please see the documentation of [lib2fas-python](https://github.com/robinvandernoord/lib2fas-python) for more details on
+using this as a Python library.
