This could be a neat thing - configure gentype automatically whenever adding to an existing project with TS already installed. We could: - Detect the config needed for `"module"` and `"moduleResolution"` in gentype via `tsconfig.json` - Warn of `allowJs` is not `true` in `tsconfig.json` and explain why it's needed Going for a "1 command to get setup" approach. cc @cometkim
