+It's a RESTfull application which will allows easy database manipulation. 
 
-### Example endpoints
+### Endpoints
 
-`GET:localhost/api"` - will provide json of tables inside database 
+`GET:localhost/api"` - provide json of tables inside database 
 
-`GET:localhost/table_name/` - will provide json of columns inside table
+`GET:localhost/table_name/` - provide json of columns and their values inside table
 
-`GET:localhost/api/table_name/column_name/` - will provide json of objects inside column
+`GET:localhost/api/table_name/column_name/` - provide json of values inside column
 
-`GET:localhost/api/table_name/id` - will provide json object specific to this id 
+`GET:localhost/api/table_name/id` - provide json-serilazed value from database
 
-`POST:localhost/api/sqlcommand` - will allow execute global query to database. For example creating new table.
+`POST:localhost/api/sqlcommand` - execute sql command to database.

+$ curl -X GET http://localhost:5417/api/users
+```
 
 ### Manifest of goals
 
 API **will** provide endpoint for each table and table column inside database.
 
-API **will** allow execute any SQL query.
+API **will** allow execute any SQL command.
 
 API **will NOT** protect from SQL injections. It's up to user manage security stuff.
