Deployment tip
Harper-ls Windows Deployment Tip: Download the pre-built harper-ls binary from the official GitHub releases at github.com/Automattic/harper/tree/master/harper-ls (under Windows assets), then deploy it silently via script to %LOCALAPPDATA%harper-ls—the default data directory—and add this path to the system %PATH% environment variable using setx /M PATH "%PATH%;%LOCALAPPDATA%harper-ls" for enterprise-wide LSP access in editors like VS Code or Neovim. Configure via LSP settings (e.g., userDictPath="%LOCALAPPDATA%harper-lsuser_dict.txt") or environment variables like HARPER_LS_USER_DICT_PATH for custom dictionaries at scale.
