 4 | ## Usage
 5 | ![forthebadge](https://forthebadge.com/images/badges/60-percent-of-the-time-works-every-time.svg)
 6 | 
 7 | `<template name>, count` where count is an optional parameter specifying number of images returned.
 8 | 
 9 | Examples: 
10 | * `i am in danger, 3` – returns top 3 image for the query
11 | * `i am once again asking for your financial support` – returns 1 image for the query
12 | 
13 | 
14 | ## Setting up
15 | To set up your own version of this Whatsapp bot
16 | - Create an account on Twilio and obtain the auth token and account SSID.
17 | - Set up the Whatsapp sandbox on Twilio. ([Docs here](https://www.twilio.com/docs/whatsapp/api#twilio-sandbox-for-whatsapp))
18 | - Deploy this node project to service of your choice. I prefer `repl.it`
19 | - Create `.env` file with the following:
20 | 
21 | ```
22 | 
23 | TWILIO_ACCOUNT_SID = Your account SSID (obtained from Twilio)
24 | 
25 | TWILIO_AUTH_TOKEN = Twilio Authorisation Token (obtained from Twilio)
26 | 
27 | SANDBOX_NUMBER = The twilio number with which you interact (obtained from Twilio)
28 | 
29 | ```
