+Articles should state what you need to understand in order to read them *at the start*.
+They should not assume the reader knows much beyond common terminal commands, and should not provide a link to some other resource half-way through an article.
+
+People should be able to read an article from the beginning, then keep going until the end, and then stop.
+Articles should not take a detour through a chain of other articles of unknown size.

+
+# Warm Up
+
+1. Deep breath.
+1. Cup of tea.
+1. Remove the old LaTeX junk you've installed.  Search for 'texlive' or 'latex' in your package manager's installed files.
+1. Find `tlmgr` in your package manager.
+
+# `tlmgr`
+
+The LaTeX Package manager is known as `tlmgr`, and often resides in `/opt/texlive/${YEAR}/bin/x86_64-linux/tlmgr`.
+Double-check the location:
+
+```sh
+ls -l /opt/texlive/${YEAR}/bin/x86_64-linux/tlmgr
+ls /opt/texlive/${YEAR}/texmf-dist/scripts/texlive/tlmgr.pl 
+```
+
+Double-check the year.
+It should *not* match the real year, it should match the `texlive`.
+
+## Problems along the Path
+
+You can't use `tlmgr` unless it's in the `$PATH`.
+
+Check if it *is* in the `$PATH` then if it *should* be in the path:
+
+```sh
+echo $PATH
+grep texlive -r /etc/profile*
+```
+
+If `tlmgr` is where it should be, but not in the path, you can add it temporarily:
+
+
+```sh
+export PATH=${PATH}:/opt/texlive/${YEAR}/bin/x86_64-linux
+```
+
+...or just reboot.
+
+## Usage
+
+Search packages:
+
+
+```sh
+tlmgr search --global epstopdf
+```
+
+Can't find what you need?
+Search for a specific file instead:
+
+```sh
