How to use blockcert project (Step by step)

Hi everyone. I’m Phát. i’m from Viet Nam
I have read through the topic about blockcert and projects, specifically on github as follows link :
But I still don’t understand how to deploy the demo on the device. Can any one show me how to use it. Sincerely thank you!

Hi there!
I’ve been exploring the same thing a while now and was able to come up with a development guide.
NOTE: I haven’t tested it myself yet, so not sure about it!
You need to:
-creating cert template - /blockchain-certificates/cert-tools
-issuing cert on the blockchain - /blockchain-certificates/cert-issuer
-verifying cert - /blockchain-certificates/cert-verifier-js
(All the above links are for their GitHub repositories)
All of these are JS libraries.

I would appreciate if someone were to suggest changes in this.
