+
+## Rules for making
+
+- Only for Neovim plugins. Vim script-made plugin and plugin that also work with Vim are excluded.
+- Put competing plugins in the same category for ease of selection.
+- The one at the top of the category is my recommendation.
+- For plugins with multiple functions (null-ls.nvim), write the function names in parentheses.
+- Separate categories as much as possible.
+
+## Tips
+
+### LuaSnip snippet for easy badge pasting
+
+```lua
+	s("badge_link", {
+		t({ "- [" }),
+		i(1, { "repo/name" }),
+		f(function(args, snip)
+			return string.format(
+				"](https://github.com/%s) ![](https://img.shields.io/github/stars/%s) ![](https://img.shields.io/github/last-commit/%s) ![](https://img.shields.io/github/commit-activity/y/%s)",
+				args[1][1],
+				args[1][1],
+				args[1][1],
+				args[1][1]
+			)
+		end, { 1 }),
+	}),
+```
