 ## Writing good commit messages
 
-In addition to writing properly formatted commit messages, it's important to include relevant information so other developers can later understand *why* a change was made. While this information usually can be found by digging code, mailing list archives, pull request discussions or upstream changes, it may require a lot of work.
+In addition to writing properly formatted commit messages, it's important to include relevant information so other developers can later understand *why* a change was made. While this information usually can be found by digging code, mailing list/Discourse archives, pull request discussions or upstream changes, it may require a lot of work.
 
 For package version upgrades and such a one-line commit message is usually sufficient.
