+Silent Install
+--------------
+
+The Windows installer supports silent installs. Here are some sample commands, supporting
+the new features of the 3.0 installer.
+
+Install CouchDB without a service, but with an admin user:password of ``admin:hunter2``:
+
+.. code-block:: batch
+
+    msiexec /i apache-couchdb-3.0.0.msi /quiet ADMINUSER=admin ADMINPASSWORD=hunter2 /norestart
+
+The same as above, but also install and launch CouchDB as a service:
+
+.. code-block:: batch
+
+    msiexec /i apache-couchdb-3.0.0.msi /quiet INSTALLSERVICE=1 ADMINUSER=admin ADMINPASSWORD=hunter2 /norestart
+
+Unattended uninstall of CouchDB:
+
+.. code-block:: batch
+
+    msiexec /x apache-couchdb-3.0.0.msi /quiet /norestart
+
+Unattended uninstall if the installer file is unavailable:
+
+.. code-block:: batch
+
+    msiexec /x {4CD776E0-FADF-4831-AF56-E80E39F34CFC} /quiet /norestart
+
+Add ``/l* log.txt`` to any of the above to generate a useful logfile for debugging.
