-at the time of writing. It's directly from documentation excluding the plugin
+See the documentation linked on the bottom, but here are some explanations
-names, but I will want it everywhere.
+anyway:
+
+- `bracketSameLine: true` - HTML tags closing on the same line as something else
+  just looks so much better for my eyes.
+- `endOfLine: auto` - The default is `lf` line-endings, which I support in
+  general, but I think `prettier` is the wrong place to configure it. I have it
+  in `.gitattributes` which will take priority on check-in and `.editorconfig`.
+- `insertPragma: true` - adds a comment on files formatted
+- `overrides` and `plugins` - self-explanatory, but if not see the documentation
+  (bottom of the page). I know I don't actually have `.prettierrc` as it's
+  `.prettierrc.json`, but it doesn't seem to hurt and `babel` seems to be used
+  for JavaScript by default, which those two are regardless of the name.
+- `proseWrap: always` - wraps long markdown lines as individual newlines don't
+  matter (two begin a new paragraph).
+- `quoteProps: consistent` - quotes things if anything is quoted.
+- `requirePragma: false` - the other side of `insertPragma: true`, it's here as
+  a note to self.
+- `singleAttributePerLine: true` - I just think it looks better.
