You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: local_file.rb
    path of file: ./repos/backup/lib/backup/syncer/cloud
    
    the code of the file until where you have to start completion: require "digest/md5"

module Backup
  module Syncer
    module Cloud
      class LocalFile
        attr_reader :path
        attr_accessor :md5

       
    
          def find(dir, excludes = [])
            dir = File.expand_path(dir)
            hash = {}
            find_md5(dir, excludes).each do |file|
              hash[file.path.sub(dir + "/", "")] = file
            end
            hash
          end
