-Migrated to [dzuchun.ing](https://git.dzuchun.ing/dzu/nvim-config)
+This is my personal nvim config.

+I do not take any credit for of the plugins or configurations used - these are all
+default configs (just copied over, so that it's easier to change what I want), or snippets
+from random articles on the Internet (if that's the case, then it's likely for "CRED:"
+link for be somewhere around).
+
+Organization, lua codestyle, and bare necessity plugins were inspired by [this playlist][nvim-from-scratch].
+Can't recommend it enough.
