Select one of these and delete the others:

If adding a new definition:

• The package does not already provide its own types, or cannot have its .d.ts files generated via --declaration
• If this is for an npm package, match the name. If not, do not conflict with the name of an npm package.
• Create it with dts-gen --dt, not by basing it on an existing project.
• Represents shape of module/library correctly
• tslint.json should contain { "extends": "dtslint/dt.json" }, and no additional rules.
• tsconfig.json should have noImplicitAny, noImplicitThis, strictNullChecks, and strictFunctionTypes set to true.

If changing an existing definition:

• Provide a URL to documentation or source code which provides context for the suggested changes: <>
• If this PR brings the type definitions up to date with a new version of the JS library, update the version number in the header.

If removing a declaration:

• If a package was never on Definitely Typed, you don't need to do anything. (If you wrote a package and provided types, you don't need to register it with us.)
• Delete the package's directory.
• Add it to notNeededPackages.json.
