+
+A collection of all token providers. The token providers should be used when the authorization
+type is going to be token based. For example, the `bearer` authorization type set using
+[httpBearerAuth trait][http-bearer-auth-trait] in Smithy.
+
+## Static Token Provider
+
+```ts
+import { fromStatic } from "@aws-sdk/token-providers";
+
+const token = { token: "TOKEN" };
+const staticTokenProvider = fromStatic(token);
+
+const staticToken = await staticTokenProvider(); // returns { token: "TOKEN" }
+```
+
+## SSO Token Provider
+
+```ts
+import { fromSso } from "@aws-sdk/token-providers";
+
+// returns token from SSO token cache or ssoOidc.createToken() call.
+const ssoToken = await fromSso();
+```
+
+## Env Token Provider with Signing Name
+
+```ts
+import { fromEnvSigningName } from "@aws-sdk/token-providers";
+
+// returns token from environment, where token's key is based on signing name.
+const envSigningNameToken = await fromEnvSigningName({ signingName: "signing name" });
+```
+
+## Token Provider Chain
+
+```ts
+import { nodeProvider } from "@aws-sdk/token-providers";
+
+// returns token from default providers.
+const token = await nodeProvider();
+```

+### Development
+
+This package contains a minimal copy of the SSO OIDC client, instead of relying on the full client, which
+would cause a circular dependency.
+
+When regenerating the bundled version of the SSO OIDC client, run the esbuild.js script and then make the following changes:
+
+- Remove any dependency of the generated client on the credential chain such that it would create
+  a circular dependency back to this package. Because we only need the `CreateTokenCommand`, the client, and this command's
+  associated `Exception`s, it is possible to remove auth dependencies.
+- Ensure all required packages are declared in the `package.json` of token-providers.
