 Submitting documentation changes
 ================================
 
-Please see the top level README file in this repository for details of where
-to send patches.
+Please refer to our contributor guide here: https://docs.yoctoproject.org/contributor-guide/
+for full details on how to submit changes.
+
+As a quick guide, patches should be sent to docs@lists.yoctoproject.org
+The git command to do that would be:
+
+     git send-email -M -1 --to docs@lists.yoctoproject.org
+
+The 'To' header can be set as default for this repository:
+
+     git config sendemail.to docs@lists.yoctoproject.org
+
+Now you can just do 'git send-email origin/master..' to send all local patches.
+
+Read the other sections in this document and documentation/standards.md for
+rules to follow when contributing to the documentation.
