-## Backend
+## Installation
-
-### Requirements
- - MariaDB or MySQL
- - node `10.12` or higher
- - Configure database in `.env`-file or environment variables. See `.env` for reference
- - Set API-Key for meteostat.net in `.env`-file or environment variable
- - import `setup.sql` for sample data
-
-### Start
- - Run `$(cd backend && npm run start)`
- - call http://localhost:3000/v1/update/climate to fetch climate data for sample entries.
- 
-### Search
- Customize your search with query parameters. For now, only climate parameters are supported. If you omit climate queries, all climate parameters will be randomized. 
-  
- Following queries are supperted by now:
- - from=YYYY-MM-DD   _(required)_
- - to=YYYY-MM-DD   _(required)_
- - temperature=NUMBER,NUMBER
- - raindays=NUMBER,NUMBER
- - sunhours=NUMBER,NUMBER
- - precipitation=NUMBER,NUMBER
-
-__Examples:__
-http://localhost:3000/v1/search?from=2020-06-14&to=2020-07-29&temperature=27,29&raindays=8,12&sunhours=250,300
-http://localhost:3000/v1/search?from=2020-06-14&to=2020-07-29
-
-
-### More
-To get more search results, add more entries with meteostat station IDs to the `regions` table in the database
-
-
-
-## Frontend
-
-### Installation
  - Install node 10.15.3
  - Run "(cd frontend && npm i)"
 
-### Start dev server
+# Start dev server
  - Run "(cd frontend && npm run start)"
