 ## configuration
 
 you can configure repo2html by changing environment variables in the `post-receive` hook file.
 
 for details about the environment variables, refer to the list below:
 
-- `GIT_WWW`: the web directory where repo2html generates static git repositories. for example, `/var/www/git/`.
-- `GIT_WWW_CLONE_URL`: the url that people will use when downloading your git repository. if you have git-daemon set up, then you can prefix the url with `git://`. otherwise, prefix the url with `http://`. for example, `git://git.example.com`. **note**: avoid slashes at the end of the url.
-- `GIT_WWW_TITLE`: the text that populates the `<title>` html tag.
-- `GIT_WWW_DESCRIPTION`: a string that populates the `description` meta information about your git repository.
-- `GIT_WWW_H1`: the text that populates the `<h1>` html tag.
+- `REPO2HTML_PREFIX`: the web directory where repo2html generates static git repositories. for example, `/var/www/git/`.
