+**** Roam
+***** Basic settings
+I'll just set this to be within =Organisation= folder for now, in the future it
+could be worth seeing if I could hook this up to a [[https://nextcloud.com/][Nextcloud]] instance.
+#+BEGIN_SRC emacs-lisp

+#+END_SRC
+***** Registering roam protocol
+The recommended method of registering a protocal is by registering a desktop
+application, which seems reasonable.
+#+BEGIN_SRC conf :tangle ~/.local/share/applications/org-protocol.desktop
+[Desktop Entry]
+Name=Org-Protocol
+Exec=emacsclient %u
+Icon=emacs-icon
+Type=Application
+Terminal=false
+MimeType=x-scheme-handler/org-protocol
+#+END_SRC
+To associate ~org-protocol://~ links with the desktop file,
+#+BEGIN_SRC shell
+xdg-mime default org-protocol.desktop x-scheme-handler/org-protocol
+#+END_SRC
+***** Graph visuals
+By default roam uses an unstyled ~graphviz~ dot. This is both uncomplicated, and
+underwhelming. We can do substantially better.
+#+BEGIN_SRC emacs-lisp

+#+BEGIN_SRC css :tangle misc/roam-graphviz-style.css
+svg {
+  position: relative;
+  top: 50%;
+  left: 50%;
+  transform: translate(-50%, -50%);

 By default, ~url-hexify-string~ seemed to cause me some issues. Replacing that in
