What does "Uses `vim.snippet` under the hood for snippet expansion" mean?

I'm a bit confused: AFAICT, there's no Lua code in this plugin that invokes any `vim.snippet` functions.

I do see that the README instructs you to set up shortcuts that invoke `vim.snippet`:

I do understand that one way to use nvim-snippets is to use it as a `nvim-cmp` source. My understanding is that in that configuration, it's `nvim-cmp` that will invoke `vim.snippet.expand`, *not* nvim-snippits.

IIUC, this plugin is providing snippets in a Lua table format that is compatible with the `vim.snippet.expand` api. Am I understanding that correctly?

Start with the README setup section linked in the issue and compare its shortcut instructions with the described nvim-cmp configuration. Clarify whether the plugin invokes vim.snippet directly or provides snippet data for another component to expand. Done means the README wording answers that distinction for newcomers.
