+## MacOS
+### Prepare deps
+
+Install common deps:
+```
+$ brew install openssl git
+```
+
+Install [gflags](https://github.com/gflags/gflags), [protobuf](https://github.com/google/protobuf), [leveldb](https://github.com/google/leveldb):
+```
+$ brew install gflags protobuf leveldb
+```
+
+### Compile brpc with config_brpc.sh
+git clone brpc, cd into the repo and run
+```
+$ sh config_brpc.sh --headers=/usr/local/include --libs=/usr/local/lib --cc=gcc --cxx=clang++
+$ make
+```
+To not link debugging symbols, add `--nodebugsymbols` and compiled binaries will be much smaller.
+
+**Run example**
+
+```
+$ cd example/echo_c++
+$ make
+$ ./echo_server &
+$ ./echo_client
+```
+
+Examples link brpc statically, if you need to link the shared version, `make clean` and `LINK_SO=1 make`
+
+To run examples with cpu/heap profilers, install `gperftools` and re-run `config_brpc.sh` before compiling.
+
+**Run tests**
+
+Install and compile googletest (which is not compiled yet):
+
+```shell
+git clone https://github.com/google/googletest && cd googletest/googletest && mkdir build && cd build && cmake .. && make && sudo mv libgtest* /usr/lib/ && cd -
+```
+
+Rerun `config_brpc.sh`, `make` in test/, and `sh run_tests.sh`
+
+### Compile brpc with cmake
+```
+$ mkdir build && cd build && cmake .. && make
+```
+
+To not link debugging symbols, use `cmake -DWITH_DEBUG_SYMBOLS=OFF ..` and compiled binaries will be much smaller.
+
+**Run example with cmake**
+```
+$ cd example/echo_c++
+$ mkdir build && cd build && cmake .. && make
+$ ./echo_server &
+$ ./echo_client
+```
+Examples link brpc statically, if you need to link the shared version, use `cmake -DEXAMPLE_LINK_SO=ON ..`
+
+**Run tests**
+
+Install gtest like just written above.
+
+```
+$ mkdir build && cd build && cmake -DBUILD_UNIT_TESTS=ON .. && make
+$ cd test && sh run_tests.sh
+```
