It appears that the documentation on readthedocs has not been built at least since 5175d4ac. In the "latest" documentation build under Obtaining Source Files, the instructions feature a misleading filename under the Environ subhead tar zxvf qe-X.Y.Z.tar.gz which I believe should be something like tar zxvf Environ-X.Y.Z.tar.gz.
In any case, it seems like this instruction has been removed from the source code but has not been updated on the documentation.
