1. How to setup 1.1. place whole application in web server. use appropriate value of parameters in .env APP_URL=http://erp.dev -- replace with exact domain DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 -- Database port on which mysql running DB_DATABASE=erp -- create a blank database in mysql and put the database name here DB_USERNAME=root -- database user name DB_PASSWORD= -- database user password MAIL_USERNAME=alamin16au@gmail.com -- set sender email address MAIL_PASSWORD=xxxxxx -- password to authenticate

   1.2. run 'php artisan migrate' and 'php artisan db:seed --class=Categories' . This will create tables with proper relationship.

   1.3. The application holding an order.json file containing sample order in ../public direcorty. Right now application will read order from this file. When this application will be atached with the third-party application from where order will come it need to change at line 23 in SaleController.

2. How to operate 2.1. run http://domain/order . This will place order in the system. Fristly it will check is the customer is an existing one otherwise it will create new customer. Then it will check whether the order is valid/consist any ordered item. If it is valid it creates order with items. 2.2. If it need to change logical/physical status of any item just click on the field. it will allow you to change status on that page. If you want attach any item with an other you need to go to edit of that item and put the order number.

3. Here I feel I no need to run additional background script as all this will be done based on different action.
