# TIDE

TIDE is the website and NixOS module for the Torah Im Derech Eretz community.
It serves the static landing page at `torahimderecheretz.com`, deploys the
forum with NixOS Discourse, and configures its production Borg backup.

## Landing page

The landing page is a static HTML and CSS site in [`site`](./site). Build its
deployment package with:

```console
nix build .#landing-page
```

## NixOS module

Import `nixosModules.tide` or `nixosModules.default`, then provide the runtime
secret paths:

```nix
services.tide = {
  enable = true;
  secretFiles = {
    adminPassword = "/run/secrets/tide-admin-password";
    mailPassword = "/run/secrets/tide-mail-password";
    secretKeyBase = "/run/secrets/tide-secret-key-base";
    borgPassphrase = "/run/secrets/borg-passphrase";
    borgPrivateKey = "/run/secrets/borg-private-key";
  };
};
```

The module owns the landing page and forum hostnames, site identity, SMTP
configuration, and backup policy. The importing host owns secret provisioning
and ACME account configuration.
