+# Build Extensions
+
+After creating the base image using buildDockerImage.sh, use buildExtensions.sh to build an extended image that will include all features present under the extensions folder.
+
+Once you have created the base image, go into the **extensions** folder and run the **buildExtensions.sh** script:
+
+    [oracle@localhost dockerfiles]$ ./buildExtensions.sh -h
+
+    Usage: buildExtensions.sh -a -x [extensions] -b [base image]  -t [image name] [-o] [Docker build option]
+    Builds one of more Docker Image Extensions.
+
+    Parameters:
+       -a: Build all extensions
+       -x: Space separated extensions to build. Defaults to all
+           Choose from : patching
+       -b: Base image to use
+       -t: name:tag for the extended image
+       -o: passes on Docker build option
+
+LICENSE UPL 1.0
+
+Copyright (c) 2020 Oracle and/or its affiliates. All rights reserved.
+
+The resulting image can be used in the same fashion as the base image.

+Applies patches on oracle home. Multiple one-offs can be applied in a single build but only 1 RU can be applied.
+
+Download the release update and one-offs and place them under extensions/patching/patches directory inside subfolders release_update and one_offs respectively.
+
+Once the patches have been placed in the correct directories, use the buildExtensions.sh script to build the extended image with patch support.
