Installation of userposts module

I download userposts module.
Then I copy it to modules/ directory.
On my website I go to Admin->Modules and can't see userposts on the list of modules!

I read the INSTALL file, see this instruction:

1. Copy the 'userpage' directory to the Drupal modules/ directory. Drupal will
automatically detect it. Then enable the module.

What is userpage? I guess author means userposts. Okay!

I take a look into other modules directories. They contains .info files.
I decide to copy one of such files and modify it for userposts module.

After a qiute easy modification I go to Admin->Modules again.
See userposts is now on the list of modules.

So now I can enable and use it.

Attachment is a userposts.info file.
