First React deployment

Hi!
This time I decided, I will try to deploy my app. In the past I deployed my another app to Heroku, so it wasn't my first time. I thought it will be hard and complicated because it's React app but actually it was quick and simple. Here are steps I followed to get deployed app

• First of all I found this tutorial. Every step is described very fine there.
• I could skip first 2 steps, because I already had project on GitHub and on my pc. So I moved to step 3 and installed "gh-pages" DevDependecy
• After that I added "homepage" property into my package.json and 2 scripts to scripts section:

"homepage": "http://jakubkus.github.io/Food-Picker",

"scripts": {
  "predeploy": "npm run build",
  "deploy": "gh-pages -d build",

• 5th step I could skip either
• 6th step was the first problem I had with deployment but I fixed it very fast. I thought if my local repository is connected to remote one, then I don't have to do anything in this step. But the problem was that I named my connection "gh" and I had to add another with original name "origin". After that it worked perfectly.
• Finally the last thing left to do was to use 1 command "npm run deploy". It made production version of my app and pushed it to new branch "gh-pages". On my project's GitHub in settings I had to enable GitHub Pages and choose branch and my project was actually published!

Now you can go and try my app here :) Thanks for reading. Have a good day/night! ;D
