tlbuild: install-tl DESCRIPTION
A.3 DESCRIPTION
===============
This installer creates a runnable TeX Live installation from various
media, including over the network, from local hard disk, a DVD, etc.
The installer works on all platforms supported by TeX Live. For
information on initially downloading TeX Live, see
<https://tug.org/texlive/acquire.html>.
The basic idea of TeX Live installation is for you to choose one of
the top-level _schemes_, each of which is defined as a different set of
_collections_ and _packages_, where a collection is a set of packages,
and a package is what contains actual files.
Within the installer, you can choose a scheme, and further customize
the set of collections to install, but not the set of the packages. To
work at the package level, use 'tlmgr' (reference just below) after the
initial installation is complete.
The default is 'scheme-full', which installs everything, and this is
highly recommended.
