Could you provide some information on what kind of a background you have in development? That will enable others to help you better.
As far as GitHub goes, I’m guessing you are also not very comfortable with git in general. I recommend you go to learngitbranching.com: this website has interactive git tutorials you can jump in straight away. You only need to do some of the initial lessons to get the hang of it. By spending even less than an hour on this website, you’ll know most of what you will need to for a long time. It also has a section called “remote” which will be helpful in learning how pulling, pushing, etc work for remote repositories like those on GitHub. All of this is going to be very useful to you if you are going to regularly deploy models, put your code on GitHub, etc. Nonetheless, the best part is that this won’t take any longer than an hour to get through.
If there are particular features of GitHub you want to familiarize yourself with, you can go to https://lab.github.com and go through any relevant tutorials. Right now you should just go through their “Introduction to GitHub” tutorial: it’s a very short tutorial that you can complete in less than 10 minutes and know more than what you need to get started without having to search the web for every little thing.
In that case, if you only need to make minor adjustments you can open
app/static/style.css in the repo and edit any specific parts of it to change how your page looks. CSS looks mostly like English, so you should be well on your way here with a few google searches. You can also edit
app/view/index.html to have more control over your webapp but it may be harder for you to make sense of this file if you aren’t familiar with HTML. Try looking at how it’s structured and make educated guesses on what you need to edit.
The best course of action here according to me is (that will pay dividends later on in life) that you should go through a small course which introduces you to web development in general so that you have a fundamental understanding of how these Web apps work and so that you’re never handicapped as a data scientist when having to deal with them (which will be quite often).
Just by the end of the third week of this course, you will know way more than enough to create and deploy such a web app of your own from scratch. They also teach you git and Github in the beginning so that’s a plus for you. This course has a lot of positive reviews all over the internet, I’m sure you’ll like it
Anyways, I hope this helped!
