# Cwtch Server
|
||||
|
||||
## Building
|
||||
|
||||
Pretty straight forward:
|
||||
- build the app in `app/` with `go build`
|
||||
- build the docker container in `docker/` with `docker build . -t openpriv/server`
|
||||
|
||||
### Windows
|
||||
|
||||
The server package relies on sqlite which in turn requires the use of CGO. As per [this issue](https://github.com/golang/go/issues/12029) that means [TDM-GCC](https://jmeubank.github.io/tdm-gcc/download/) is required to be installed and used to compile on Windows
|
||||
|
||||
## Running
