-#### Generating multiple schemas
-
-In your `package.json`, for each schema you’d like to transform add one `generate:specs:[name]` npm-script. Then combine
-them all into one `generate:specs` script, like so:
-
-```json
-"scripts": {
-  "generate:specs": "npm run generate:specs:one && npm run generate:specs:two && npm run generate:specs:three",
-  "generate:specs:one": "npx openapi-typescript one.yaml -o one.ts",
-  "generate:specs:two": "npx openapi-typescript two.yaml -o two.ts",
-  "generate:specs:three": "npx openapi-typescript three.yaml -o three.ts"
-}
-```
-
-If you use [npm-run-all][npm-run-all], you can shorten this:
-
-```json
-"scripts": {
-  "generate:specs": "run-p generate:specs:*",
-```
-
-You can even specify unique options per-spec, if needed. To generate them all together, run:
-
-```bash
-npm run generate:specs
-```
-
-Rinse and repeat for more specs.
-
-For anything more complicated, or for generating specs dynamically, you can also use the [Node API](#node).
