+===== Merge strategies =====
+==== ours ====
+Technically record a merge while totally ignoring its content -- for record-keeping.
+Example:
+<code>
+$ git checkout master
+$ git merge --strategy=ours <obsolete branch>
+</code>
+How to make ''master'' look exactly like ''develop'':
+<code>
+$ git checkout topic
+$ git merge -s ours master
+$ git checkout master
+$ git merge --ff-only topic
+</code>
+To do this for an arbitrary commit, create a temporary branch:
+<code>
+$ git checkout -b tempbranch <commit ID>
+$ git merge -s ours master
+$ git checkout master
+$ git merge --ff-only tempbranch
