 # Python-Library-Template
-A template for Python Library
+
+This is a template for a Python library. It includes a README.md file, 
+a .gitignore file, some Github Actions, a directory for the library code
+and a directory for the tests. A module for logging is included in the 
+library code.
+
+## Using the template
+
+This template is available as a repository on GitHub. To start a new 
+library using this template, click on the green "Use this template"
+button on the repository page (or blue if you are using dark mode).
+Or simply click 
+[here](https://github.com/new?template_name=python-library-template&template_owner=framunoz). 
+
+## Adding a license
+
+This template does not include a license file. If you want to add a
+license to your project, you can do so by creating a new file called
+`LICENSE` in the root directory of the project. You can use the
+[choosealicense.com](https://choosealicense.com/) website to help you
+choose a license.
+
+GitHub allows you to add a license to your project if you create a file
+called `LICENSE` in the root directory of the project. You can choose a
+license from a list of common licenses or add a custom license.
+
+## Starting a new library
+
+Before starting a new library, you should change the name of the library
+as you wish. You can do this by changing the name of the directory
+`library`. 
+
+Next, you should install ``poetry`` if you haven't already. You can do this
+by running the following command:
+
+```bash
+pip install --upgrade pip
+pip install poetry
+```
+
+Then, you should run the following command to initialize a new Python
+project:
+
+```bash
+python -m poetry init
+```
+
+Poetry will ask you some questions about the project. You can answer them
+as you wish. After that, you can see the `pyproject.toml` file that
+Poetry has created. The tree structure of the project should look like this:
+
+```
+<PROJECT-NAME>
+├── .github
+│   └── workflows
+│       └── pep8.yml
+│       └── tests.yml
+├── .gitignore
+├── README.md
+├── pyproject.toml
+├── <LIBRARY-NAME>
+│   └── __init__.py
+│   └── logging_.py
+└── tests
+    └── __init__.py
+```
+
+Where `<LIBRARY-NAME>` is the name of the library you chose.
+
+When you want to add a new dependency to the project, you can run the
+following command:
+
+```bash
+poetry add <DEPENDENCY>
+```
+
+Where `<DEPENDENCY>` is the name of the dependency you want to add.
