+# Notes on using LaTeX
+
+To possibly save your self from headache:
+
+* Fedora: `sudo dnf install texlive-scheme-full -y`
+* Debian: `sudo apt install texlive-full -y`
+
+## Simple boilerplate
+
+Refer to `hello.tex`
+
+## Package management
+
+***Don't do this, use `YOURFAVOURITEPACKAGEMANAGER search texlive-moderncv`
+or whatever***
+
+Fedora: remember to `sudo dnf install texlive-msg texlive-texlive-msg-translations` to
+remove one nag. Which doesn't work with Finnish, naturally.
+
+```bash
+tlmgr init-usertree
+tlmgr --ignore-warning --usermode install moderncv
+```
+
+## Installing custom templates
+
+1. Put them to `~/texmf/tex/latex/local/` The `tlmgr init-usertree` might be useful?
+  * This can be verified with `kpsewhich -var-value=TEXMFHOME` in case this
+    happened to be not-Linux.
+2. Run `texhash ~/texmf`
+
