-Pro Tip: if you have multiple remotes, try prepending `SPC u` to the calls to the git-link
-
-Pro Tip #2: You can select a region and use git-link to have the whole region selected in the link
-
-Pro tip #3: The link is openned automatically, but it's copied to the clipboard
-too if you don't want for any reason to have the link opened all the time, put this on your `dotspacemacs/config`:
-```elisp
-(setq git-link-open-in-browser nil)
-```
+**Notes**
+- You can use the universal argument `SPC u` to select a remote repository.
+- You can use `git-link` on a region.
+- When the link is opened, the URL is also copied in the kill ring, you can
+override this behavior by setting the variable `git-link-open-in-browser` to
+`nil`.
