+### Divergence from upstream
+
+I try to stay as up-to-date as possible with upstream. However certain commits
+that I deliberately skipped cherry-picking because they can be problematic. I
+will try to document all of them below.

+* [nvim-lua/kickstart@7513ec8](https://github.com/nvim-lua/kickstart.nvim/commit/7513ec8a7dd579957ce2d9b44e05c1da18d7d0e3)
+deletes `numToStr/Comment.nvim` without justification. Possibly this feature
+was merged in `neovim-v0.10.0`? The changes to use `vim.uv` instead of
+`vim.loop` were not included as a result. I also want to take the time to
+understand what `neodev` and `lazydev` do before integrating the latter. Future
+commits related to it will not be included here either, such as.

+~/.local/bin/markdownlint` or something similar.
