+# Validation Configuration
+The configuration file for validations is written in JSON. Each file has two sections.
+
+	{
+	  "headers" : {
+		...
+	  },
+
+	  "columns" : {
+		 ...
+	  }
+	}
+
+## header section
+In the header section a list of headers are defined. The CSV file should have the same headers in the same order. Otherwise the validation fails.
+
+	"headers" : {
+		"list": ["COLUMN 1","COLUMN 2","NAME","SOME OTHER COLUMN"]
+	}
+
+
+## column section
+In the column section, each column that should be validated, should have an entry. Columns without the need of validation can be omitted. Each column can have multiple validations and each of them is checked.
+
+	"columns" : {
+		  "COLUMN 1": {
+			"integer" : true,
+			"not empty" : true,
+			"maxlength" : 4,
+			"minlength" : 4
+		  },
+		  
+		  "COLUMN 2": {
+			"value of" : ["0", "1"]
+		  },
+		  
+		  "SOME OTHER COLUMN": {
+			"double" : true
+		  }
+	}	  
+
+## Available Validations
