README.md

+
+This project is to help RPM-packagers build .spec files that can pull sources 
+directly from git. The usage is something like this (inside .spec file):
+
+    URL: https://github.org/api/v3/user/projectname/repository/archive?ref=v%{version}
+    
+    %prep
+    %if 0%{?setup_from_git:1}
+    %setup_from_git -U %{url} -S %{S:0} -n %{name}-%{version}
+    %else
+    # setup compatible with github-generated tarball
+    %setup -c -T
+    tar axf %{S:0} --strip-components 1
+    %endif
+
+The included macro must be appended to either `~/.rpmmacros` or one of the site macro files
+(see `man rpmbuild`)
