+INTRODUCTION                                                  *kickstart.nvim*
+
+Kickstart.nvim is a project to help you get started on your neovim journey.
+
+                                                            *kickstart-is-not*
+It is not:
+- Complete framework for every plugin under the sun
+- Place to add every plugin that could ever be useful
+
+                                                                *kickstart-is*
+It is:
+- Somewhere that has a good start for the most common "IDE" type features:
+    - autocompletion
+    - goto-definition
+    - find references
+    - fuzzy finding
+    - and hinting at what more can be done :)
+- A place to _kickstart_ your journey.
+    - You should fork this project and use/modify it so that it matches your
+      style and preferences. If you don't want to do that, there are probably
+      other projects that would fit much better for you (and that's great!)!
