+
+### Start developing
+* Install node.js
+```
+$ git clone git@github.com:koodiklinikka/koodiklinikka.fi-api.git
+$ cd koodiklinikka.fi-api
+$ npm install
+```
+
+* Create `config.json` file. See [config.template.json](https://github.com/koodiklinikka/koodiklinikka.fi-api/blob/master/config.template.json) for possible options.
+The config file consists of environment specific blocks. Environment variable `NODE_ENV` determines which block is used. If the environment variable is not present, the `development` block will be selected. 
+`all` block is always used and the block selected is merged into it so that it overwrites the values defined in it.
+
+* ```
+$ npm start
+```
