+```
+src/
+    cli.py OR app.py
+    constants.py
+    __init__.py
+tests/
+requirements.txt
+setup.py
+```
 
+## `requirements.txt`
+
+Dependencies used within the venv for the project, e.g:
+
+```
+google-auth==1.35.0
+google-auth-httplib2==0.1.0
+google-auth-oauthlib==0.4.6
+google-api-python-client==2.26.1
+gspread==3.7.0
+requests==2.25.1
+oauth2client==4.1.3
+```
+
+## `setup.py`
+
+The declaration file for the application, equivalent to `package.json`, e.g:
+
+```py
+from setuptools import setup, find_packages
+
+setup(
+    name="eolas-db",
+    version="0.1",
+    packages=find_packages(where="src"),
+    package_dir={"": "src"},
+    install_requires=[
+        # List your project dependencies here
+    ],
+    entry_points={
+        "console_scripts": [
+            "eolas-db=cli:main",
+        ],
+    },
+)
+```
+
+The `entry_points` key is important. This is the first execution point of the
+application. Typically you would name your entry-point script as `app.py` or
+`cli.py` and then specify its `main` function.
+
+E.g. in `cli.py`:
+
+```py
+def main():
+    print('run the application')
+
+if __name__ == "__main__":
+    main()
+
+```
+
+## `__init__.py`
