+- Edit directory listings as normal buffers — mutations are derived by diffing
+- Cross-directory move, copy, and rename across any adapter
+- Adapters for local filesystem, SSH, S3, and OS trash
+- File preview in split or floating window
+- Configurable columns (icon, size, permissions, timestamps)
+- Executable file highlighting and filetype-aware icons
+- Floating window and split layouts
 
 ## Requirements
 
-Neovim 0.8+ and optionally [mini.icons](https://github.com/nvim-mini/mini.nvim/blob/main/readmes/mini-icons.md) or [nvim-web-devicons](https://github.com/nvim-tree/nvim-web-devicons) for file icons.
+- Neovim 0.10+
+- (Optionally) any of the following icon providers:
+  - [mini.icons](https://github.com/nvim-mini/mini.nvim/blob/main/readmes/mini-icons.md)
+  - [nvim-web-devicons](https://github.com/nvim-tree/nvim-web-devicons)
+  - [nonicons.nvim](https://github.com/barrettruth/nonicons.nvim)
 
 ## Installation

 ## FAQ
 
-**Q: How do I migrate from `stevearc/oil.nvim` to `barrettruth/oil.nvim`?**
+**Q: How do I migrate from `stevearc/oil.nvim`?**
 
-Replace your `setup()` call with a `vim.g.oil` assignment. For example, with
-[lazy.nvim](https://github.com/folke/lazy.nvim):
+Change the plugin source and replace `setup()` with `vim.g.canola` in `init`.
+The configuration table is identical — only the entry point changes. For
+example, with [lazy.nvim](https://github.com/folke/lazy.nvim):
+
+Before (`stevearc/oil.nvim`):
 
 ```lua
--- before
 {
   'stevearc/oil.nvim',
+  opts = { ... },
   config = function(_, opts)
     require('oil').setup(opts)
   end,
-  opts = {
-    ...
-  }
-}
-
--- after
-{
-  'barrettruth/oil.nvim',
-  init = function()
-    vim.g.oil = {
-      columns = { "icon", "size" },
-      delete_to_trash = true,
-    }
-  end,
 }
 ```
 
+After (`barrettruth/canola.nvim`):
+
+```lua
+{
+  'barrettruth/canola.nvim',
+  opts = { ... },
+  config = function(_, opts)
+    require('canola').setup(opts)
+  end,
+}
+```
+
+`init` runs before the plugin loads; `config` runs after. oil.nvim reads
+`vim.g.canola` at load time, so `init` is the correct hook. Do not use `config`,
+`opts`, or `lazy` — oil.nvim loads itself when you open a directory.
+
+**Q: Why "canola"?**
+
+Canola oil! But...
+
 **Q: Why "oil"?**
 
-**A:** From the [vim-vinegar](https://github.com/tpope/vim-vinegar) README, a quote by Drew Neil:
+From the [vim-vinegar](https://github.com/tpope/vim-vinegar) README, a quote by

 > Split windows and the project drawer go together like oil and vinegar
 
-Vinegar was taken. Let's be oil.
-Plus, I think it's pretty slick ;)
-
-**Q: Why would I want to use oil vs any other plugin?**
-
-**A:**
-
-- You like to use a netrw-like view to browse directories (as opposed to a file tree)
-- AND you want to be able to edit your filesystem like a buffer
-- AND you want to perform cross-directory actions. AFAIK there is no other plugin that does this. (update: [mini.files](https://github.com/nvim-mini/mini.nvim/blob/main/readmes/mini-files.md) also offers this functionality)
-
-If you don't need those features specifically, check out the alternatives listed below
-
-**Q: Can oil display files as a tree view?**
-
-**A:** No. A tree view would require a completely different methodology, necessitating a complete rewrite.
