Without type definitions for our external dependencies, we are unable to typecheck anything we `import`. If you are using a dependency that does not come with type definitions, see the [typescript consumption guide](https://www.typescriptlang.org/docs/handbook/declaration-files/consumption.html) for how to find and use community-created type definitions.

-Not every JavaScript package has an available flow-typed definition. In this case, flow-typed will generate a stub file in the directory `flow-typed/npm/`. You may find it useful to fill out this stub; See the [flow-typed wiki][writing-flow-definitions] for a library definition writing guide.
