 # Timetable V2
 
-## Project Setup

+
+Timetable V2 is a **substitution plan and timetable viewer** that is meant to be a placement for the HTML files that my school provides via [~~DSB Mobile~~](https://dsbmobile.de/) [BOLLE](https://bolle-software.de/).
+
+This Project fetches the latest substitution plan files from the specified source and parses them, which converts the HTML files exported by [Untis](https://www.untis.at/) to a JSON format. The Programm then compares the new substitution plan to the previous one and finds changed, deleted and newly added substitutions and adds them to the database.
+
+The substitutions in the database and their history can then be viewed in the web browser, where they are also being filtered by class and linked with the students timetable.
+
+## Setup with Docker
+
+To setup Timetable V2 in a docker container, you firstly have to build the docker image:
+
+```sh
+docker-compose build
+```
+
+Next you will need to set your environment variables. For that rename `.env.sample` in the server directory to `.env` and change the variables as described in the file.
+
+Then you can run the app
+
+```sh
+docker-compose up -d
+```
+
+And check its logs
+
+```sh
+docker-compose logs -f
+```
+
+If everything is working, you should be able to connect to the app at http://localhost:3000 (or the IP address of your docker host)
+
+## Setup for Development
+
+To setup a development environment for Timetable V2, you will need to have NodeJS and Docker installed. (If you don't want to install Docker, you can also install PostgreSQL natively on your computer)
+
+### Build the frontend
+
+To build the Vue.js based frontend, you will need to be in the root folder of the project and run
 
 ```sh
 npm install
+npm run build
 ```
 
-### Compile and Hot-Reload for Development
+Or if you want to work on the frontend you can run
 
 ```sh
 npm run dev
 ```
 
-### Compile and Minify for Production
+This creates a development server with live reload on port 3001. This also proxies all API routes to the backend running on port 3000.
+
+### Run the backend
+
+First you will need to install a PostgreSQL instance. This can be simply done by launching a PostgreSQL docker container:
 
 ```sh
-npm run build
+docker run --name timetable-postgres -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres
+
 ```
 
-### Lint with [ESLint](https://eslint.org/)
+The backend can be found at `./server`, so all upcomming commands need to be run in that directory.
+
+For the app to be able to fetch substitution plan files, you need to create a `.env` file (you can use the `.env.sample` as a template) and set the values correctly. You don't need to change the database url used in `.env.sample` for development.
+
+To apply the database schema to the newly created database, you need to run:
 
 ```sh
-npm run lint
+npx prisma db push
+```
+
+Now you just need to install the dependencies and are ready to run the app:
+
+```sh
+npm install
+node index.js
 ```
