#### Using Docker
1. Create directories ```files``` and ```meta``` and run ```chown -R 65534:65534 meta && chown -R 65534:65534 files```
2. Create a config file (example provided in repo), we'll refer to it as __linx-server.conf__ in the following examples
Example running
```
docker run -p 8080:8080 -v /path/to/meta:/data/meta -v /path/to/files:/data/files andreimarcu/linx-server
docker run -p 8080:8080 -v /path/to/linx-server.conf:/data/linx-server.conf -v /path/to/meta:/data/meta -v /path/to/files:/data/files andreimarcu/linx-server -config /data/linx-server.conf
```
Example with docker-compose
