prompt: Your task is to convert the following English description into an ASCII tree format.
  
  cli is a core directory that incorporates 3 subdirectories: config, connhelper and context.
  At the main level, 'config' retains 3 subdirectory elements: configfile, credentials, types.
  At level 2, in directory path 'config → configfile', Inside 'configfile', you'll find it has nothing inside.
  In nested path 'config → credentials', Inside 'credentials', you'll find it stands empty.
  At level 2, in directory path 'config → types', Inside 'types', you'll find it is blank.
  Back to the top level.
  At the main level, 'connhelper' groups 2 subdirectories: commandconn, ssh.
  Within directory hierarchy 'connhelper > commandconn', Inside 'commandconn', you'll find it is a vacant space.
  In nested path 'connhelper > ssh', 'ssh' hasn't been filled with any content.
  Back to the top level.
  At the top level, 'context' shelters 2 directories: docker, store.
  In nested path 'context > docker', 'docker' contains nothing at present.
  Within directory hierarchy 'context > store', Inside 'store', you'll find it contains nothing at present.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
