 To use the `requester_pays` option, you need to configure your AWS credentials.
 See [the AWS documentation](https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html) for instructions.
 
-#### USGS EROS
-
-The USGS EROS system, which hosts landsat data, requires a personal access token to download assets.
-Here's how to create and use your personal access token with **stac-asset**:
-
-1. [Create a new personal access token](https://ers.cr.usgs.gov/password/appgenerate)
-2. Set two environment variables:
-    - `USGS_EROS_USERNAME` to your username (found in the top right of the web UI)
-    - `USGS_EROS_PAT` to your personal access token
-3. Use `UsgsErosClient.default()` to create a new client.
-
-You can also provide your username and password to the `UsgsErosClient.login` method.
-
 #### Earthdata
 
 You'll need a personal access token.
