+setup-armnn.sh [OPTION]...
+  --tflite-delegate
+    setup dependencies for the Arm NN TF Lite Delegate
+  --tflite-parser
+    setup dependencies for the Arm NN TF Lite Parser
+  --onnx-parser
+    setup dependencies for the Arm NN ONNX parser
+  --all
+    setup dependencies for all Arm NN components listed above
+  --target-arch=[aarch64|aarch32|x86_64]
+    specify a target architecture (mandatory)
+  --num-threads=<INTEGER>
+    specify number of threads/cores to build dependencies with (optional: defaults to number of online CPU cores on host)
+  -h, --help
+    print brief usage information and exit
+  -x
+    enable shell tracing in this script
+
+At least one dependency flag (e.g. --tflite-delegate) must be provided or else provide --all to setup all dependencies.
+Directories called "source" and "build" will be generated in the current directory (ROOT_DIR) from which this script is called.
+It's recommended to call this script in a directory outside of this Arm NN source repo, to avoid nested repositories.
+
+This script will download the latest release branches of Arm NN and ACL, by default.
+Alternatively, manually create a "source" directory in ROOT_DIR and place custom repositories there.
+Custom repositories in "source" must be named "armnn" and "acl".
+
+Examples:
+Setup for aarch64 with all Arm NN dependencies:
+    <PATH_TO>/setup-armnn.sh --target-arch=aarch64 --all
+Setup for aarch64 with TF Lite Delegate and TF Lite Parser dependencies only:
+    <PATH_TO>/setup-armnn.sh --target-arch=aarch64 --tflite-delegate --tflite-parser
+Setup for aarch32 with all Arm NN dependencies:
+    <PATH_TO>/setup-armnn.sh --target-arch=aarch32 --all
