+## Description
+
+DCAE MOD's DCAE design tool is based on Nifi 1.9.2 with modifications
+made by the DCAE MOD team.
+
+## Development
+
+The designtool-web module contains the modified versions of Nifi files, along
+with a Dockerfile and a script (sh/applypatches.sh) for replacing them in
+the nifi Docker image, to produce the design tool Docker image.
+
+If the set of modified files changes, then the Dockerfile, the script, and
+potentially the pom.xml may require changes.
+
+In particular, note that the Nifi build creates 2 "bin" files, one for nifi
+itself and the other for the nifi-toolkit, which are expanded into separate
+directories in the nifi image.  Contained in the "bin" files are "nar" files,
+which contain "jar" and "war" files.  And, inside the nifi-web-ui "war" file
+are several "-all.js" and "-all.css" files, containing minified aggregations
+of the various js and css source files.  The applypatches script needs to
+appropriately patch these nar, war, jar, all.js, and all-css files (some of
+which also have gzipped versions).
+
+The nifi-war-to-jar module builds a jar archive from the classes in the
+nifi-web-api war archive, that the modified files in the designtool-web
+module can be compiled against.
