-Some Material components for Compose for Web, based on [Material Web (Web Components)](https://github.com/material-components/material-web) (preferred) and [Material Components for the web](https://github.com/material-components/material-components-web) (fallback)
+Some Material components for Compose for Web, based on [Material Web (with Web Components) (or material-web, or `mwc`)](https://github.com/material-components/material-web) (preferred) and [Material Components for the web (or material-components-web, or `mdc`)](https://github.com/material-components/material-components-web) (fallback)
 
-This project is in prototype and the components are not complete. More components will be added. It will probably go through huge refactors and API changes, too.
+~~This project is in prototype and the components are not complete. More components will be added. It will probably go through huge refactors and API changes, too.~~
+
+**This project is not currently under active development. Here is a list of reasons and alternatives:**
+
+1. The [material-web](https://github.com/material-components/material-web) team is working on Material You (Material Design 3) support and [the Material 2 branch (`mwc`)](https://github.com/material-components/material-web/tree/mwc) is no longer under active development. Existing Compose wrappers of their Material 2 components are still kept in [the `:compose-web-material` subproject](compose-web-material) but not updated.
+1. [KMDC](https://github.com/mpetuska/kmdc) wrapping around [material-components-web (`mdc`)](https://github.com/material-components/material-components-web) provides a much more complete set of Material Design components for Compose for Web.
+1. We are currently focusing more on [compose-multiplatform-material](https://github.com/huanshankeji/compose-multiplatform-material) to provide multiplatform Compose Material wrappers, whose web portion depends on KMDC and [the `:compose-web-common` subproject](compose-web-common), which may be occasionally updated for the dependent project.
 
 ## Instructions on how to use
 Some configurations are needed to use this library due to the immaturities of this project and Kotlin/JS.
