+### ResolveRequire
+
+This function allows plugin to manually resolve `require('...')` file paths. Useful for environments that implement custom require resolution.
+
+Return `nil` to use default LuaLS resolution. If you return an empty table - LuaLS will not resolve paths.
+
+```Lua
+---@param  uri  string # The URI of file
+---@param  name string # Argument of require()
+---@return string[]?
+function ResolveRequire(uri, name) end
+```
