 ## Usage
 
+### Installation
+
+```sh
+npm install calamine-node
+# or: pnpm add calamine-node
+# or: bun add calamine-node
+```
+
+Requires Node.js >=22.13 or Bun. Prebuilt native binaries are installed automatically
+on the supported platforms; a Rust toolchain is only needed to build from source.
+Keep optional dependencies enabled so your package manager installs the matching binary.
+
 Use `read` for complete data with automatic cleanup. Use `openFile`, `openBuffer`,
 or `openStream` to keep a workbook open for inspection or repeated reads.
 A workbook is a spreadsheet file; a sheet is one tab inside it.
