 It implements the JNI methods for pixels-index-rockset to operate Rockset (RocksDB Cloud).
 
 ### Build Instructions
+This module is built and tested with:
+
+- GCC/G++ with C++11 support (version 4.8 or later)
+- RocksDB Cloud `v6.7.3`
+- AWS SDK for C++ installed under `/usr/local`
+
+The RocksDB Cloud version is pinned in `CMakeLists.txt` as `ROCKSDB_CLOUD_GIT_TAG v6.7.3`.
+Do not switch it to `master`: newer RocksDB headers are not ABI/API compatible with this module.
+
 1. We download and install rocksdb-cloud automatically in the CMakeLists of pixels-index-rockset.
    However, the compilation process of rocksdb-cloud assumes that the AWS c++ SDK is installed in
    the default location of /usr/local. You can follow the steps listed here https://github.com/aws/aws-sdk-cpp (version 1.7.325 or later).
-   Here are the instructions for your reference:
+   Following the RocksDB Linux - Ubuntu instructions, install the prerequisite packages first:
+```bash
+sudo apt-get install \
+  libgflags-dev \
+  libsnappy-dev \
+  zlib1g-dev \
+  libbz2-dev \
+  liblz4-dev \
+  libzstd-dev \
+  libcurl4-openssl-dev
+```
+   Or on CentOS / RHEL, prepare the prerequisites like this:
+```bash
+# GCC/G++ with C++11 support
+sudo yum install gcc48-c++
+
+# gflags
+git clone https://github.com/gflags/gflags.git
+cd gflags
+git checkout v2.0
+./configure && make && sudo make install
+# If installed to /usr/local, export CPATH=/usr/local/include:$CPATH
+# and LIBRARY_PATH=/usr/local/lib:$LIBRARY_PATH
+
+# snappy / zlib / bzip2 / lz4 / optional ASAN
+sudo yum install snappy snappy-devel
+sudo yum install zlib zlib-devel
+sudo yum install bzip2 bzip2-devel
+sudo yum install lz4-devel

+2. Use the CI/bootstrap build script. It supports Ubuntu and CentOS/RHEL-like systems, installs the documented system dependencies, installs AWS SDK for C++ under `/usr/local` when missing, and then runs the native build.
+Provide Java separately in the environment before running it:
+```bash
+cd cpp/pixels-index/pixels-index-rockset
+./ci-build.sh
+```
+The script checks and/or prepares:
+- `cmake`, `make`, `git`
+- `PIXELS_HOME`
+- `JAVA_HOME` and JNI headers
+- `gcc` and `g++` in `PATH`, with version `4.8` or later
+- RocksDB build dependencies for Linux, including Ubuntu and CentOS/RHEL variants: `gflags`, `snappy`, `zlib`, `bzip2`, `lz4`, `zstd`, `libcurl`
+- AWS SDK for C++ installed under `/usr/local`
+After a successful build, it also installs `libpixels-index-rockset.so` and the required `librocksdb.so*` runtime libraries into `$PIXELS_HOME/lib`.
+
+If you need to run the native build commands manually after the environment is ready, the script executes the equivalent workflow:
 ```bash
+export CC=/path/to/gcc
+export CXX=/path/to/g++
 mkdir build && cd build
 cmake .. # in the output of this command, check whether the correct JNI version is used
 make
