## Installation
The latest release of nix-init is packaged in nixpkgs and kept up to date on the unstable branches
![](https://repology.org/badge/vertical-allrepos/nix-init.svg)
If you want to use a more recent snapshot of nix-init, it is also available as a flake.
The following command is equivalent to running `nix-init --help`:
```bash
nix run github:nix-community/nix-init -- --help
```
or if you don't have flakes enabled:
```bash
nix run --extra-experimental-features "flakes nix-command" github:nix-community/nix-init -- --help
```

## Configuration
nix-init will try to find `nix-init/config.toml` under XDG configuration directories
```toml
# ~/.config/nix-init/config.toml
# maintainers that will get added to the package meta
maintainers = ["figsoda"]
# path to nixpkgs, equivalent to `--nixpkgs`
nixpkgs = "<nixpkgs>"
# access tokens to access private repositories and avoid rate limits
[access-tokens]
"github.com" = "ghp_blahblahblah..."
"gitlab.com".command = ["secret-tool", "or", "whatever", "you", "use"]
"gitlab.gnome.org".file = "/path/to/api/token"
