 # shortenurl.nvim
 
-Small neovim plugin to shorten urls, using shlink and the shorten-url scripts in my dotfiles.
\ No newline at end of file
+This is a small neovim plugin that can convert urls to short urls, using the `shoren-url` bash script found in my
+dotfiles repo.
+
+## Usage
+
+```lua
+vim.pack.add({
+    { src = "https://git.housh.dev/michael/shortenurl.nvm" },
+})
+```
+
+### Create keybinds
+
+```lua
+vim.keymap.set({ 'n', 'v', 'x' }, '<leader>lc', function()
+    require('shortenurl').convertUrl()
+end, { desc = "[L]ink [c]onvert to short url." })
+
+vim.keymap.set('n', '<leader>ls', function()
+    require('shortenurl').prompt()
+end, { desc = "[L]ink [s]horten, prompting for url." })
+
+vim.keymap.set('n', '<leader>lv', function()
+    require('shortenurl').convertFromClipboard()
+end, { desc = "[L]ink convert url from cliboard to short url." })
+```
