+
+    This plugin should be configured through blink-cmp's `sources.providers` settings.
+
+    For example:
+
+    ```nix
+    plugins.blink-cmp = {
+      enable = true;
+      settings.sources.providers = {
+        latex-symbols = {
+          module = "blink-cmp-latex";
+          name = "Latex";
+          opts = {
+            # set to true to insert the latex command instead of the symbol
+            insert_command = false
+          };
+        };
+      };
+    };
+    ```
+
+    And then you can add it to blink-cmp's `sources.default` option:
+
+    ```nix
+    plugins.blink-cmp = {
+      enable = true;
+      settings.sources.default = [
+        "lsp"
+        "path"
+        "luasnip"
+        "buffer"
+        "latex-symbols"
+      ];
+    };
+    ```
+  '';
+
+  # Configured through blink-cmp
+  callSetup = false;
+  hasLuaConfig = false;
+  hasSettings = false;
+}
