+There are a few things worth noting before you start:
+
+  - No two build scripts shall run at the same time as `/usr/bin/protoc` is
+    globally overridden. Do not especially run two build scripts targeting
+    different ORT versions.
+  - If you have protobuf compiler installed here, please remember to back it up
+    before running the build in case it is overwritten by another version.
+  - Ensure that `miniconda` is not present or that it does not interfere with
+    the header lookup mechanism.
+
 Now you can run the build script and let it run until completion. No user
-interaction or sudo permissions are required.
+interaction is required.
+
+```bash
