-- Parameters used by scene tiling updated for TiTiler 0.11.x. Previously, parameters
-  were for TiTiler 0.6.0. The `bidx`
-  parameter was named `asset_bidx` and the `assets` parameter was to be passed once for
-  each value instead of with a comma-separated list of values. It is unknown when these
-  parameters changed, but it is recommended that TiTiler >= 0.11.x is used.

-### TiTiler
-
-The scene and mosaic views require instances of TiTiler be deployed and configured.
-
-The configuration `SCENE_TILER_URL` must be pointed at a TiTiler deployment. At
-least 0.11.x is recommended, but this may work with other versions 0.7.x and greater.
-
-The configuration `MOSAIC_TILER_URL` must be pointed at a deployment of the
-[Element 84 TiTiler MosaicJSON fork](https://github.com/Element84/titiler-mosaicjson)
-of the [NASA IMPACT Titiler fork](https://github.com/NASA-IMPACT/titiler). This
-adds support for creating mosaics from STAC API searches to Titiler.
-
-If the Mosiac TiTiler is deployed, it can be used for both the scene and mosaic tiler URL
-configurations.
