+    Add Git Status to oil.nvim directory listings.
+
+    Git status is added to the listing asynchronously after creating the oil directory
+
+    listing so it won't slow oil down on big repositories. The plugin puts the status in two new sign columns
+
+    the left being the status of the index, the right being the status of the working directory
+
+    `win_options.signcolumn` needs to be configured in `plugins.oil.settings`:
+    ```nix
+    plugins.oil = {
+      enable = true;
+      settings = {
+        win_options = {
+          signcolumn = "yes:2,";
+        };
