+# Flask_Basic
+![logo](https://github.com/prabhakarvenkat/Flask_Basic/blob/94bd3b3d6d8f4736188bff6dcead36b086ad8f5a/flask.png)
+
+This repo has been updated to work with `Python v3.8` and up.
+
+## How To Run
+1. Install `virtualenv`:
+```
+$ pip install virtualenv
+```
+
+2. Open a terminal in the project root directory and run:
+```
+$ virtualenv env
+```
+
+3. Then run the command:
+```
+$ .\env\Scripts\activate
+```
+
+4. Then install the dependencies:
+```
+$ (env) pip install -r requirements.txt
+```
+
+5. Finally start the web server:
+```
+$ (env) python app.py
+```
+
+This server will start on port 5000 by default. You can change this in `app.py` by changing the following line to this:
+
+```python
+if __name__ == "__main__":
+    app.run(debug=True, port=<desired port>)
+```
+
+## Contributing
+
+Since this is a repository for an introduction, the code should remain the same as the code that was shown in the repository. Any pull requests that don't address security flaws or fixes for language updates will be automatically closed. Style changes, adding libraries, etc are not valid changes for submitting a pull request.
+Thank you.
