## Mini App Example
You can find this example in our Github repository:
[supervisely-ecosystem/ui-widgets-demos/text-elements/005\_markdown/src/main.py](https://github.com/supervisely-ecosystem/ui-widgets-demos/blob/master/text%20elements/005_markdown/src/main.py)
### Import libraries
```python
import os
import supervisely as sly
from dotenv import load_dotenv
from supervisely.app.widgets import Card, Container, Flexbox, Markdown, Button
```
### Init API client
First, we load environment variables with credentials and init API for communicating with Supervisely Instance:
```python
load_dotenv("local.env")
load_dotenv(os.path.expanduser("~/supervisely.env"))
api = sly.Api()
```
### Initialize `Button` widgets, we will use
```python
button_text = Button(text="Set md text")
button_clean = Button(text="Clean md")
button_readme = Button(text="Set md readme")
buttons_container = Flexbox(widgets=[button_text, button_clean, button_readme])
```
### Initialize `Markdown` widget
```python
md_path = "path/to/README.md"
md = ""
with open(md_path, "r") as f:
md = f.read()
markdown = Markdown(height=400)
```
### Create app layout
Prepare a layout for the app using `Card` widget with the `content` parameter and place widget that we've just created in the `Container` widget.
```python
card = Card(title="Markdown", content=Container([markdown, buttons_container]))
layout = Container(widgets=[card], direction="vertical")
```
### Create app using layout
Create an app object with the layout parameter.
```python
app = sly.Application(layout=layout)
```
### Handle button clicks
```python
@button_text.click
def simple_content():
markdown.set_content("### Title \n *some markdown text*")
@button_clean.click
def clear_content():
markdown.set_content("")
@button_readme.click
def readme_content():
markdown.set_content(md)
```
