+# Overlays
+
+This directory contains composable Nix overlays used by the Neovim wrapper configuration. Each overlay is small and focused, so you can reuse or override them downstream.
+
+## Files
+
+- `r.nix`  
+  R-related overrides (rix overlay). Exposes `pkgs.rpkgs` from rstats-on-nix and creates pre-configured `rWrapper` and `quarto` with standard R packages.
+
+- `python.nix`  
+  Python-related overrides and package additions (e.g., extra Python packages).
+
+- `plugins.nix`  
+  Neovim plugin overrides (e.g., patching or pinning plugin derivations).
+
+- `default.nix`  
+  Aggregates and exports the overlays in a composable way. Includes the fran overlay for custom R packages.
+
+## Exports from `default.nix`
+
+`overlays/default.nix` exposes:
+
+- `rOverlay` - rix overlay for R packages from rstats-on-nix
+- `franOverlay` - fran overlay for custom R packages and tools  
+- `pythonOverlay`  
+- `pluginsOverlay`  
+- `dependencyOverlays` (list of overlays in order)  
+- `dependencyOverlay` (composed overlay via `lib.composeManyExtensions`)  
+- `default` (alias of `dependencyOverlay`)  
+- `dependencies` (alias of `dependencyOverlays`)
+
+## Downstream usage examples
+
+### Use the composed default overlay
+
+```/dev/null/example.nix#L1-18
+{
+  inputs,
+  ...
+}:
+let
+  overlayDefs = import ./overlays/default.nix inputs;
+in {
+  nixpkgs.overlays = [
+    overlayDefs.default
+  ];
+}
+```
+
+### Use specific overlays only
+
+```/dev/null/example.nix#L1-22
+{
+  inputs,
+  ...
+}:
+let
+  overlayDefs = import ./overlays/default.nix inputs;
+in {
+  nixpkgs.overlays = [
+    overlayDefs.rOverlay
+    overlayDefs.pluginsOverlay
+  ];
+}
+```
+
+### Extend with your own overlay (composition)
+
+```/dev/null/example.nix#L1-29
+{
+  inputs,
+  ...
+}:
+let
+  overlayDefs = import ./overlays/default.nix inputs;
+  myOverlay = final: prev: {
+    # Example: override a package
+    myTool = prev.myTool.override { /* ... */ };
+  };
+in {
+  nixpkgs.overlays = [
+    overlayDefs.default
+    myOverlay
+  ];
+}
+```
+
+## Adding a new overlay
+
+1. Create a new overlay file in this directory (e.g., `foo.nix`).
+2. Import it in `overlays/default.nix` and add it to `dependencyOverlays`.
+3. Optionally expose it as a named export (e.g., `fooOverlay`) for downstream reuse.
+
+## Notes
+
+- Keep overlays composable and focused.
+- Avoid monolithic overlays; prefer small, purpose-specific overlays.
+- When overriding plugins, keep patches minimal and document the intent.

+#   - pkgs.rpkgs: R packages from rstats-on-nix
+#   - pkgs.rpkgs.rPackages: All CRAN packages

+#
+# Custom R packages and tools (radianWrapper, air-formatter) come from
