Behind the scenes

How are identified applicable files

Activated only if one of these files is found: .vale.ini
File extensions: .md, .rst

How the linting is performed

vale is called once with the list of files as arguments (list_of_files CLI lint mode)

Example calls

vale README.md file1.md file2.md file3.md

vale --config .vale.ini README.md file1.md file2.md file3.md
