+TODO: Prevent the user from overriding mini.snippits mappings?
+
+An extra for mini.snippets.
+Includes a completion source for `nvim-cmp`
+There is an open issue for `blink.cmp`: https://github.com/Saghen/blink.cmp/issues/741
+
+For now, `blink.cmp` is out of scope in this extra. 
+Use extra "mini_snippets_standalone" to expand the snippets from the lsp with blink.
+
+Currently, mini.snippets is in "beta": See https://github.com/echasnovski/mini.nvim/issues/1428
+
+Example override for your own config:
+return {
+  {
+    "echasnovski/mini.snippets",
+    opts = function(_, opts)
+      -- By default, for opts.snippets, the extra for mini.snippets only adds gen_loader.from_lang()
+      -- This provides a sensible quickstart, integrating with friendly-snippets
+      -- and your own language-specific snippets
+      --
+      -- In order to change opts.snippets, replace the entire table inside your own opts
+
+      local snippets, config_path = require("mini.snippets"), vim.fn.stdpath("config")
+
+      opts.snippets = { -- override opts.snippets provided by extra...
+        -- Load custom file with global snippets first (order matters)
+        snippets.gen_loader.from_file(config_path .. "/snippets/global.json"),
+
+        -- Load snippets based on current language by reading files from
+        -- "snippets/" subdirectories from 'runtimepath' directories.
+        snippets.gen_loader.from_lang(), -- this is the default in the extra...
+      }
+    end,
+  },
+}
