-## about database configuration
-
-You can configure two database, one for development, other for production, at the same time in the configuration file (better in user secret file):
-
-```json
-{
-  "DatabaseConfig": {
-    "UseDevelopment": true,
-    "ConnectionString": "The secret production database string. (MySql)",
-    "DevelopmentConnectionString": "The private development database string. (Sqlite)"
-  }
-}
-```
-
-Set `UseDevelopment` to `true` to use `DevelopmentConnectionString` as sqlite connection string. Set `UseDevelopment` to `false` to use `ConnectionString` as mysql connection string. Usually you set it to `true` in development mode and `false` in production mode. But you may have to use production database to do migration in development so you may also set it to `false` in development to do that. The migrations for two database are different because they use different providers and remember to use it to switch to right database when do migration.

-If you have better solution to deal with database, please don't hesitate to tell me. 😛
