## Getting Started
### Nix shell (reproducible development environment)
If `nix` is available, can get several reproducible build environments
```
$ cd xo-umbrella2
$ nix-shell -A shell0 # just nix stdenv: make,gcc,bash etc.
$ nix-shell -A shell1 # stable environment
$ nix-shell -A shell2 # stable environment + emacs + lsp
$ nix-shell -A shell # bleeding edge environment
```
### Cmake build
If `nix` is available, you probably prefer the nix build.
