[RUBY] TECH CAMP learning personal app ④ git ignore

What is 5K! ??

While creating a personal app, I noticed that I did not make a pull request to Git Hub while creating user management. It was written with caution that a lot of data was accumulated and something like "5K" was displayed in the workspace and I could not pull request all.

Changes was displayed as ** 500 ** on the Git Hub desktop, and it became ** 500 !! ?? **. Does this mean 5K? ??

And I wondered if it was too late, how to make a pull request, or if I had to delete one of the files, and somehow deleted some files.

However, that alone didn't work at all, and it didn't decrease, and I just googled and googled, and finally I found ** git ignore !!!** I made a .git ignore file in VS code and put the following code.

Now the changes have been reduced to 91 at once, and you can now make pull requests.
