+# tiny-checktime.nvim
+
+A tiny plugin for Neovim 0.12+ that checks for externally modified files when
+focus returns.
+
+Zero config. ~12 lines of Lua.
+
+## Features
+
+- Runs `:checktime` on focus gain and terminal events
+- Pairs with `autoread` to auto-reload changed files
+- Configurable trigger events
+- Works out of the box — no setup call required
+
+## Requirements
+
+- Neovim >= 0.12
+
+## Installation
+
+Add to your `vim.pack.add()` call:
+
+```lua
+"https://github.com/swaits/tiny-checktime.nvim",
+```
+
+## Configuration
+
+All options are optional. Call `setup()` only if you want to customize:
+
+```lua
+require("tiny-checktime").setup({
+  events = { "FocusGained", "TermClose", "TermLeave" },
+})
+```
+
+## How it works
+
+When Neovim regains focus (switching back from another app or terminal pane),
+it runs `:checktime` to ask Neovim to check if any buffers were modified on
+disk. Combined with `vim.opt.autoread = true`, changed files reload
+automatically.
