Here's a draft README.md file for the plugin:

A Neovim plugin to copy or append timestamps.

This plugin provides two commands:

• TimestampCopy: Copies the current timestamp to the system clipboard
• TimestampAppend: Appends the current timestamp to the word under the cursor

The TimestampCopy command depends on the xclip clipboard tool. You'll need to install xclip separately.

use 'username/timestamp.nvim'

use {
  'username/timestamp.nvim'
}

After installing, two commands are available:

• TimestampCopy: Copies the current timestamp to the clipboard
• TimestampAppend: Appends the current timestamp to the word under the cursor

You can add keymaps to invoke the commands:

vim.api.nvim_set_keymap('n', '<leader>tc', '<cmd>TimestampCopy<CR>', {noremap = true, silent = true})
vim.api.nvim_set_keymap('n', '<leader>ta', '<cmd>TimestampAppend<CR>', {noremap = true, silent = true})

This will map <leader>tc to TimestampCopy and <leader>ta to TimestampAppend.

If you encounter any issues, please create a [new issue].

Hope this helps! Let me know if you have any other questions or suggestions for the README.
