-### Optional Peer Dependencies for TypeScript
-
-This package has optional peer dependencies for TypeScript users.
-Recent versions of npm will automatically install peer dependencies by default.
-For those users, no additional steps are necessary for full TypeScript support,
-however users should still explicitly install the latest types (see the next section).
-
-Other package managers require peer dependencies to be added manually.
-Refer to any warnings generated by your package manager
-about missing peer dependencies and install them as needed.
-Refer to the next section for keeping the types updated.
-
-#### Keeping up with the latest types
-
-This package depends on [@seamapi/types] for the latest TypeScript types.
-New versions of this SDK are generally not released when new types are published.
-Unless your project frequently runs a blanket `npm update`,
-the types will become outdated with the Seam API over time.
-Thus, users of this package should explicitly install the types with
-
-```
-$ npm install -D @seamapi/types
-```
-
-and update them when consuming new API features with
-
-```
-$ npm install -D @seamapi/types@latest
-```
-
