# Welcome to Streamlit 👋



**A faster way to build and share data apps.**



Streamlit lets you turn data scripts into shareable web apps in minutes, not weeks. It’s all Python, open-source, and free! And once you’ve created an app you can use our [Community Cloud platform](https://streamlit.io/cloud) to deploy, manage, and share your app.



## Installation



Open a terminal and run:



```bash

$ pip install streamlit

$ streamlit hello

```



If this opens our sweet _Streamlit Hello_ app in your browser, you're all set! If not, head over to [our docs](https://docs.streamlit.io/library/get-started) for specific installs.



The app features a bunch of examples of what you can do with Streamlit. Jump to the [quickstart](#quickstart) section to understand how that all works.



Streamlit Hello



## Quickstart



### A little example



Create a new file `streamlit_app.py` with the following code:

```python

import streamlit as st

x = st.slider("Select a value")

st.write(x, "squared is", x * x)

```



Now run it to open the app!

```

$ streamlit run streamlit_app.py

```



Little example



### Give me more!
