 # MapGuesser
 
-This is the MapGuesser Application project.
+This is the MapGuesser Application project. This is a game about guessing where you are based on a street view panorama - inspired by existing applications.
 
-License: GNU AGPL 3.0
+## Installation
+
+### Clone the Git repository
+
+The first step is obviously cloning the repository to your machine:
+
+```
+git clone https://gitea.e5tv.hu/esoko/mapguesser.git
+```
+
+All the commands listed here should be executed from the repository root.
+
+### Setup Docker stack (recommended)
+
+The easiest way to build up a fully working application with web server and database is to use Docker Compose with the included `docker-compose.yml`.
+
+All you have to do is executing the following command:
+
+```
+docker-compose up -d
+```
+
+Attach shell to the container of `mapguesser_app`:
+
+```
+docker exec -it mapguesser_app_1 bash
+```
+
+All of the following commands should be executed there.
+
+### Manual setup (alternative)
+
+If you don't use the Docker stack you need to install your environment manually. Check `docker-compose.yml` and `docker/Dockerfile` to see the system requirements.
+
+### Initialize project
+
+This command installes all of the Composer requirements and creates a copy of the example `.env` file.
+
+```
+composer create-project
+```
+
+### Set environment variables
+
+The `.env` file contains several environment variables that are needed by the application to work properly. These should be configured for your environment.
+
+One very important variable is `DEV`. This indicates that the application operates in development (staging) and not in production mode.
+
+**Hint:** If you install the application in the Docker stack for development (staging) environment, only the variables for external dependencies (API keys, map attribution, etc.) should be adapted. All other variables (for DB connection, static root, mailing, multiplayer, etc.) are fine with the default value.
+
+#### API keys
+
+**You should set the API keys that enable playing the game. Without these API keys the application cannot work well. To get Google API keys visit this page: https://console.developers.google.com/**
+
+Required Google APIs:
+* **Maps JavaScript API**: for the interactive maps and street views
+* **Maps Static API**: for the static map images
+* **Street View Static API**: for the backend metadata requests
+
+Required API keys:
+* **GOOGLE_MAPS_SERVER_API_KEY**: this it used by the backend and should have access to **Street View Static API**
+* **GOOGLE_MAPS_JS_API_KEY**: this is used by the frontend and should have access to **Maps JavaScript API** and **Maps Static API**
+
+Additionally, a tile provider is also needed for map editor. This should be configured by `LEAFLET_TILESERVER_URL`, `LEAFLET_TILESERVER_SUBDOMAINS` and `LEAFLET_TILESERVER_ATTRIBUTION`. You can find some providers here: https://wiki.openstreetmap.org/wiki/Tile_servers. OpenStreetMap's tile server is fine for testing.
+Example:
+```
+LEAFLET_TILESERVER_URL=https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png
+LEAFLET_TILESERVER_SUBDOMAINS=abc
+LEAFLET_TILESERVER_ATTRIBUTION="&copy; <a href=\"https://www.openstreetmap.org/copyright\">OpenStreetMap</a> contributors"
+```
+
+### (Production only) Create cron job
+
+To maintain database (delete inactive users, old sessions etc.), the command `db:maintain` should be regularly executed. It is recommended to create a cron job that runs every hour:
+
+```
+0 * * * * /path/to/your/installation/mapg db:maintain >>/var/log/cron-mapguesser.log 2>&1
+```
+
+### Finalize installation
+
+After you followed the above steps, execute the following command:
+
+```
+scripts/install.sh
+```
+
+**Warning: Because of a known issue the image `mapguesser_multi` fails to run without the installation steps. You have to relauch `docker-compose up -d` after you finished the installation process.**
+
+**And you are done!** The application is ready to use and develop. In development mode an administrative user is also created by the installation script, email is **mapg@mapg.dev**, password is **123456**. In production mode you should create the first administrative user with the following command:
+
+```
+./mapg user:add EMAIL PASSWORD admin
+```
+
+If you installed it in the Docker stack, you can reach it on http://localhost. The mails that are sent by the application can be found on http://localhost:8080/. If needed, the database server can be directly reached on localhost:3306.
