 **Repository:** <https://github.com/epwalsh/obsidian.nvim>
 
 A Neovim plugin for writing and navigating an [Obsidian](https://obsidian.md) vault, written in Lua.
+
+This config assumes the vault location is at `~/obsidian-vault`. You can move the vault there. If you instead want to change the location in the config, you can create a new file `plugins/obsidian.lua`, copy the contents of this `init.lua` to it, and then edit the 2 following lines
+
+`event = { "BufReadPre  */obsidian-vault/*.md" },`
+
+and
+
+`dir = "~/obsidian-vault",`
+
+to match your vault location. 
+
+
+The plugin may also nag and ask you to create a `templates` directory in the vault. You can use `mkdir templates` to create an empty directory.
