+### Windows users
+
+Use Git Bash as a terminal or WSL instead of PowerShell.
+
+To avoid [issues][] with a few linters and formatters within golangci-lint,
+make sure you check out files only with LF endings:
+
+```sh
+git config core.autocrlf false
+git config core.eol lf
+```
+
+To convert an existing cloned repo from CRLF to LF, use the following commands:
+
+```sh
+git config core.autocrlf false
+git rm --cached -r .
+git reset --hard HEAD
+```
