+## CRLF vs. LF
+### Random Whitespacing in Generation (core.autocrlf)
+Git, in its attempts to be helpful, created a bunch of extra whitespaces in converting CRLF to LF. Which led to differences from the CI on Windows.
+
+So these commands help get rid of that:
+
+```bash
+# Disable Git's CRLF to LF conversion:
+git config --global core.autocrlf false
+# Reset cached files to remove associations
+git rm --cached -r .
+git reset --hard
+```
+
+You can re-enable the `core.autocrlf` option afterwards if you'd like: `git config --global core.autocrlf true`. Just don't reset the cache.
