  - Dependencies need to list `node-pre-gyp`
  - Your devDependencies should list `aws-sdk` so that you can run `node-pre-gyp publish` locally or a CI system. We recommend using `devDependencies` only since `aws-sdk` is large and not needed for `node-pre-gyp install` since it only uses http to fetch binaries
  - You should add `"bundledDependencies":["node-pre-gyp"]`. This ensures that when you publish your module that the correct version of node-pre-gyp will be included in the `node_modules` folder during publishing. Then when uses install your module `node-pre-gyp` will already be present. Without this your module will not be safely installable for downstream applications that have a depedency on node-pre-gyp in the npm tree (without bundling npm deduping might break the install when node-pre-gyp is moved in flight)
- - Your `scripts` section should optionally add `"prepublish": "npm ls"` to ensure the right node-pre-gyp version is bundled before publishing your module. If node-pre-gyp is missing or an old version is present then this will catch that error before you publish a broken package.
+ - Your `scripts` section should optionally add `"prepublishOnly": "npm ls"` to ensure the right node-pre-gyp version is bundled before publishing your module. If node-pre-gyp is missing or an old version is present then this will catch that error before you publish a broken package.
  - Your `scripts` section should override the `install` target with `"install": "node-pre-gyp install --fallback-to-build"`. This allows node-pre-gyp to be used instead of the default npm behavior of always source compiling with `node-gyp` directly.
  - Your package.json should contain a `binary` section describing key properties you provide to allow node-pre-gyp to package optimally. They are detailed below.
