+streamlit-embedcode is the easiest way to embed code snippets into your Streamlit app! This component supports the following code sharing services:
+
+- [GitHub gist](https://gist.github.com/)
+- [Gitlab snippets](https://gitlab.com/explore/snippets)
+- [Pastebin](https://pastebin.com/)
+- [CodePen](https://codepen.io/)
+- [Ideone](https://ideone.com/)
+- [TagMyCode](https://tagmycode.com/)
+
+## Installation
+
+streamlit-embedcode is distributed via PyPI:
+
+```python
+pip install streamlit-embedcode
+```
+
+## Examples
+
+Using streamlit-embedcode is as simple as importing the code service you want to use:
+
+```python
+import streamlit as st
+from streamlit_embedcode import github_gist
+
+github_gist("https://gist.github.com/randyzwitch/be8c5e9fb5b8e7b046afebcac12e5087/")
+```
+
+Optionally, you can provide arguments for `height`, `width` and `scrolling` to control the behavior of the iframe the content is displayed in.
