+# jwt-tui.nvim
+
+A Neovim plugin for [jwt-tui](https://github.com/anotherhadi/jwt-tui): open a floating JWT inspector from Neovim, optionally pre-filled with a token from your visual selection.
+
+## Requirements
+
+- Neovim 0.10+
+- [jwt-tui](https://github.com/anotherhadi/jwt-tui) installed and available in `$PATH`
+
+## Installation
+
+**lazy.nvim**
+
+```lua
+{
+  'anotherhadi/jwt-tui.nvim',
+  config = function()
+    require('jwt-tui').setup()
+  end,
+}
+```
+
+## Setup
+
+```lua
+require('jwt-tui').setup()
+```
+
+All options and their defaults:
+
+```lua
+require('jwt-tui').setup({
+  width  = 0.9,       -- fraction of editor width
+  height = 0.9,       -- fraction of editor height
+  border = "rounded", -- any value accepted by nvim_open_win
+})
+```
+
+No keymaps are set by default. Add your own:
+
+```lua
+-- open empty
+vim.keymap.set('n', '<leader>jj', '<cmd>JwtTui<cr>', { desc = 'jwt-tui: open' })
+
+-- open with visual selection as token
+vim.keymap.set('v', '<leader>jj', ':<C-u>JwtTuiOpen<CR>', { silent = true, desc = 'jwt-tui: open with selection' })
+```
+
+## Commands
+
+| Command       | Description                                         |
+| ------------- | --------------------------------------------------- |
+| `:JwtTui`     | Open the JWT inspector (empty)                      |
+| `:JwtTuiOpen` | Open with the current visual selection as the token |
+
+## Lua API
+
+You can call the functions directly in your keymaps or other plugins:
+
+```lua
+require('jwt-tui').open()                                        -- open empty
+require('jwt-tui').open({ token = '...' })                       -- pre-fill token
+require('jwt-tui').open({ token = '...', secret = 'mysecret' }) -- pre-fill token and secret
+require('jwt-tui').open_selection()                              -- open with visual selection as token
+```
