Hello Sergey! I was about to open the same Issue, but glad you already did.
Please dear maintainers this is a pretty relevant issue, and one very easy to fix, so please fix it.
I can also help by creating a PR with a simple solution for this

Went ahead and created a PR anyways:
#108

All those new here (freshly forking the repo to skills network IDE to complete the Hands-on Lab) who haven't run npm install could first:

1. Open .gitignore file and add node_modules at the end of the line

2. Commit and push this to your repository (git add . - git commit -m "add node_modules to .gitignore" - git push -u origin main)

3. To push to your repo you would be asked to authenticate first, so create a personal access token from your github profile (google it) and use the token to push by doing: git push https://<GITHUB_ACCESS_TOKEN>@github.com/<GITHUB_USERNAME>/<REPOSITORY_NAME>.git

For those who have already ran npm install and now have a huge number of files to commit:

• Add the node_modules to the end of the .gitignore file as specified above
• Run git rm -r --cache node_modules
• Now continue making your modfications to App.js file and push it to your repo (follow step 3 above)

Anyways hope the maintainers simply validate this PR and merge, so none of us have to waste time and get frustrated doing this especially for beginners.
