 ## Options
 
-atm:
+Options can currently be set via lua:
+
+```lua
+vim.g["zettel_extension"] = ".wiki"
 ```
-anchor_separator = vim.g["zettel_anchor_separator"] or vim.b["zettel_anchor_separator"] or "_",
-zettel_extension = vim.g["zettel_extension"] or vim.b["zettel_extension"] or ".md",
-zettel_root = vim.g["zettel_root"] or vim.b["zettel_root"] or "~/documents/notes",
+
+or via vimscript:
+
+```vim
+let g:zettel_extension = ".wiki"
 ```
+
+The functionality is the same. The plugin will look up options by precedence buffer > global > default.
+
+```lua
+anchor_separator = vim.b["zettel_anchor_separator"] or vim.g["zettel_anchor_separator"] or "_",
+zettel_extension = vim.b["zettel_extension"] or vim.g["zettel_extension"] or ".md",
+zettel_root = vim.b["zettel_root"] or vim.g["zettel_root"] or "~/documents/notes",
+```
+
+Since, as long as the api still changes rapidly,
+a list of options would quickly be outdated,
+what you can instead is to look into `options.lua`,
+where at the top the currently effective options with their defaults and available values are defined.
