.ignore files
Many tools use hidden files ending with ignore such as:
Most share the same syntax based on wildcards. They will "ignore" any matching file.
* # all files
*.exe # all files ending with .exe
!test.exe # do not ignore "test.exe"
build/ # any build folder
/build/ # only the build inside the root
**/build/ # any nested build folder
➡️ A .ignore file is applied starting from the root directory, which is the directory the .ignore file is in.
