+* Optional on-disk encryption
+* Optional single use pastes
+* IP/network whitelisting and blocking
+* Endpoint rate limiting
+* Fully configurable via environment variables
+* Included script for uploading files/content from stdin

+
+# Installation
+### Docker
+It is highly recommended that you use the official Docker image to run Pastey. To do so, simply run:
+```
+$ docker run -d -p 5000:5000 -v /path/to/local/dir:/app/data cesura/pastey:latest
+```
+Change **/path/to/local/dir** to a local folder you would like to use for persistent paste storage. It will be mounted in the container at **/app/data**.
+
+Pastey will then be accessable at *http://localhost:5000*
+
+
+### Local
+Requirements:
+* Python 3.8
+* AVX-enabled processor (or a Python environment configured to use Anaconda's TensorFlow)
+
+```
+$ git clone https://github.com/Cesura/pastey.git && cd pastey
+$ pip3 install -r requirements.txt
+$ python3 app.py 
+```
