<b>Hey!</b> Stan here, if you've used FossFLOW and it's helped you, <b>I'd really appreciate if you could donate something small :)</b> I work full time, and finding the time to work on this project is challenging enough.
If you've had a feature that I've implemented for you, or fixed a bug it'd be great if you could :) if not, that's not a problem, this software will always remain free!
<b>Also!</b> If you haven't yet, please check out the underlying library this is built on by <a href="https://github.com/markmanx/isoflow">@markmanx</a> I truly stand on the shoulders of a giant here 🫡

FossFLOW is a powerful, open-source Progressive Web App (PWA) for creating beautiful isometric diagrams. Built with React and the <a href="https://github.com/markmanx/isoflow">Isoflow</a> (Now forked and published to NPM as fossflow) library, it runs entirely in your browser with offline support.

## 🐳 Quick Deploy with Docker
```bash
# Using Docker Compose (recommended - includes persistent storage)
docker compose up
# Or run directly from Docker Hub with persistent storage
docker run -p 80:80 -v $(pwd)/diagrams:/data/diagrams stnsmith/fossflow:latest
```
Server storage is enabled by default in Docker. Your diagrams will be saved to `./diagrams` on the host.
To disable server storage, set `ENABLE_SERVER_STORAGE=false`:
```bash
docker run -p 80:80 -e ENABLE_SERVER_STORAGE=false stnsmith/fossflow:latest
```
