+# Games Shop
+This is the repository for the free games shop hosted on [shop.iedsoftworks.com](https://shop.iedsoftworks.com).
+
+## Developers and local testers
+To start a local variant of the site, you **need** Docker (with docker compose).
+
+### 1 Cloning the repo
+Start with cloning the repository 
+
+`git clone https://git.php.fail/neintonine/gamesshop.git`
+
+and entering the folder for it
+
+`cd gamesshop`
+
+### 2 Installing dependencies
+Then you need to install/build the NPM and composer portion.
+There are two ways of doing it.
+
+#### 2.1 Local NPM & Composer
+If you have NodeJS and PHP8.3 with composer installed, you can simply run:
+
+`npm install && npm run build && composer install`
+
+#### 2.2 Docker
+If you don't have those installed, and are unwilling to install them, you can use docker to install and build the required packages.
+
+JS: `docker run --rm  --volume "$PWD":/app -w /app node npm install && npm run build`
+
+PHP: `docker run --rm  --volume "$PWD":/app -w /app composer composer install --ignore-platform-req=ext-gd`
+
+### 3 Creating the environment file
+To run the site, you need a valid environment file. 
+#### 3.1 Copy the example
+Under the folder 'config', you can find a `.env.example`-file, which you can use to create your enviroment file.
+Start of by coping the file, and rename it to `.env`
+
+`cp config/.env.example config/.env`
+
+The example already includes settings for the database and logs.
+
+#### 3.2 Adding your Discord-App
+One thing, that the example doesn't contain is the discord app. Thats something you need to add.
+Simply create an app in the [Discord Developer Portal](https://discord.com/developers/applications) and add the required values in the environment file
+
+### 4 Creating the Database
+Now after ensuring you have the dependencies and a valid environment file, we can create the database.
+
+Again, if you have PHP installed you can just do: `php ./src/php/bin/doctrine.php orm:schema-tool:create`
+
+If you don't want to do this, just let docker to do it:
+
+```bash
+docker run -v .:/app --rm -it php:8.3-cli php /app/src/php/bin/doctrine.php orm:schema-tool:create
+```
+
+### 5 Running the containers
+Now finally, after creating the database, just go into the deploy folder (`cd deploy`) and start the compose file.
+
+You may see, that there are two file (`docker-compose.yaml` and `docker-compose-dev.yml`). As you may expect the second is for local development so probably the one you should use.
+The first does effectively the same thing, but for the production environment.
+
+```bash
+docker compose -f ./docker-compose-dev.yml up
+```
+
+Congratulations! The website should now boot up and after docker is done downloading, you should be able to use http://localhost:8080 to open the page.
