# Installation using TeX Live manager

TeX Live manager (`tlmgr`) is, by default, a shell (or Windows terminal window) command. There is voluminous documentation about it from the command

`tldoc tlmgr`

but basic operation is pretty straightforward. The manager needs to know where to download stuff from; the canonical setup is ```latex tlmgr option repository http://mirror.ctan.org/systems/texlive/tlnet ``` which passes the decision to the mirror selector. You can (of course) specify a particular archive or mirror that you trust, or even a local disc copy that you keep up-to-date (disc space and bandwidth are so cheap nowadays, that a home mirror of CTAN is a feasible proposition).

To update a single package, use: ```latex tlmgr update <package> ```

To update everything you already have in your installation, use: ```latex tlmgr update –all ```
