+# Bazel Central Registry
+
+When the ruleset is released, we want it to be published to the
+Bazel Central Registry automatically:
+<https://registry.bazel.build>
+
+This folder contains configuration files to automate the publish step.
+See <https://github.com/bazel-contrib/publish-to-bcr/blob/main/templates/README.md>

------------
+Future release
+------------
+
+6.1.4 (2025-05-01)
+------------------
+
+### Build
+- Feature: Support `bazel` build system. See #1032.
+  Proposed by Kostya Serebryany @kcc
+  If all goes well (pending), it should appear in the Bazel central repository.
+  It can be imported into your project using the following lines:
+
+  **MODULE.bazel**
+  ```bazel
+  bazel_dep(name = "ftxui", version = "6.1.4")
+  ```
+
+  **BUILD.bazel**
+  ```bazel
+  deps = [
+    // Depend on the whole library:
+    "@ftxui//:ftxui",
+
+    // Choose a specific submodule:
+    "@ftxui//:component",
+    "@ftxui//:dom",
+    "@ftxui//:screen",
+  ]
+  ```
+
 ### Component
 - Bugfix: Fix a crash with ResizeableSplit. See #1023.
   - Clamp screen size to terminal size.
