 **paste is a simple web app for writing & sharing code.** It's my own take on conventional pastebin sites like _pastebin.com_ or _hastebin_.

-### Host your own
+### Self-hosting
 
-It's quite simple to host your own version.
+The easiest way to self-host is using Docker (& Docker Compose). You can run the following commands to get started:
 
 ```bash
 git clone https://github.com/lucko/paste
 cd paste
-yarn install
-
-# Outputs html/css/js files to /build
-yarn build
-
-# Start a webserver for testing/development
-yarn start
-```
-
-You can then follow the [create-react-app deployment documentation](https://create-react-app.dev/docs/deployment/) for how to host the build output. I personally recommend deploying to the cloud using a service like Netlify instead of hosting on your own webserver.
-
-If you really want to self-host (including the bytebin data storage part), I suggest using Docker:
-
-```bash
-git clone https://github.com/lucko/paste
 docker compose up -d
 ```
