 # untis-ics-sync
 
+[![Node CI](https://github.com/bddvlpr/untis-ics-sync/actions/workflows/node-ci.yaml/badge.svg)](https://github.com/bddvlpr/untis-ics-sync/actions/workflows/node-ci.yaml) [![Docker CD](https://github.com/bddvlpr/untis-ics-sync/actions/workflows/docker-cd.yaml/badge.svg)](https://github.com/bddvlpr/untis-ics-sync/actions/workflows/docker-cd.yaml)
+
 Serves a calendar API (ICS) for events provided from Untis.
 
+![Banner](.github/assets/banner.jpg)
+
+
 ## Use case
 
 Some schools, universities, or workspaces do not enable the iCalendar API that Untis provides by default. Due to this limitation, I've written my implementation to dynamically sync class schedules to my agenda.
 
 ## Installation
 
-Simply clone the repository and cd into it using `git clone https://github.com/bddvlpr/untis-ics-sync && cd untis-ics-sync`.
-If you're planning on using Docker, you could use the [bddvlpr/untis-ics-sync](https://hub.docker.com/r/bddvlpr/untis-ics-sync/) image from Docker Hub instead of the git repository.
-
-### Redis
-
-Version 0.7.0 and above require a redis server to be supplied in environment variables for queue processing. Either externally provide one, or define one in a Docker compose environment.
+### Using Docker
 
-### Setup SSL
+To deploy a quick Docker environment, fill in the target school credentials in `docker-compose.yml` and start the service by running `docker compose up -d`. Do note that if you'd like to use SSL, add any reverse proxy such as Nginx, Caddy or Traefik. View the table below for all possible environment variables.
 
-From version 0.2.6 and forward, SSL will not be natively supported anymore. Please use a reverse proxy instead of supplying the docker container with an SSL certificate.
+### Using NixOS
 
-### Using Docker
+Firstly add this repository to your flake's inputs.
+```nix
+{
+  inputs = {
+    # ...
+    untis-ics-sync.url = "github:bddvlpr/untis-ics-sync/<rev/version>";
+    untis-ics-sync.inputs.nixpkgs.follows = "nixpkgs";
+  };
 
-To run the app using Docker, copy over the `.env.example` to `.env` and fill in the parameters to get the app to work.
-Deploy the app (in a test environment) using `docker run -d --env-list .env -p 3000:3000 bddvlpr/untis-ics-sync`.
+  # ...
+}
+```
 
-### Using Yarn
+Secondly, enable the service. Please **DO NOT** use a writeText derivative as this will add your credentials to the Nix store. Use agenix or nix-sops. A local Redis service will automatically be started.
+```nix
+{
+  inputs,
+  ...
+}: {
+  imports = [
+    inputs.untis-ics-sync.nixosModules.default
+  ];
 
-To run the app using Yarn, copy over the `.env.example` to `.env` and fill in the parameters to get the app to work.
-Hot run the app using `yarn start:dev`, or build it using `yarn build`.
+  services.untis-ics-sync = {
+    enable = true;
+    envFile = ./; # Path to your credentials.
+  };
+}
+```
