+## Updated and Consolidated Documentation
+
+### Overview
+
+The VTK (Visualization Toolkit) documentation has undergone a major update and
+consolidation to enhance its usefulness for developers. The
+`/Documentation/docs` directory now contains the contents and configuration for
+the Sphinx-based website, published on the ReadTheDocs platform at
+https://docs.vtk.org. This consolidates all existing documentation for VTK,
+including the newly added list of supported data formats, API of all VTK public
+CMake modules, the VTK formats specification (previously part of vtk-examples),
+and the general information about the VTK project. Software process and
+conventions documentation has also been moved from docs.google.com to the new
+website.
+
+In addition to the documentation website, two new resources have been
+introduced: the VTK book, which hosts the markdown version of the VTK book at
+https://book.vtk.org and VTK examples at https://examples.vtk.org, which
+contain many examples with redirects put in place to ensure the previous URL
+remains functional. Many other updates to the documentation have also been
+made, including improved documentation structure, removal of obsolete
+documents, and addition of imported third-party projects to the developer
+guide. VTK documentation now follows a versioning system and is actively
+maintained alongside the code.
+
+Contributions and feedback are welcome for all three websites to ensure that
+the VTK documentation remains up-to-date.
+
+### Next steps
+
+The next steps for the VTK documentation project include setting up a
+versioning system for docs, doxygen, and the book. Work is also underway to
+include a description of each `Modules` (as well as a `README.md` file) in
+`docs.vtk.org`. And there are plans to explore the possibility of using merge
+request previews for the documentation so that contributors don't have to
+compile it themselves.
+
+For `examples.vtk.org`, the plan is to consolidate examples from VTK and
+`vtk-examples`.
+
+Pages on the `mediawiki` site will be marked as deprecated, and a link to
+`docs.vtk.org` will be included.
+
+These efforts will help ensure that VTK documentation remains user-friendly and
+accessible to all developers.
