+## Checking out the source
+
+Since MCS is not meant to be built independently outside outside of MariaDB server, we should checkout the [server](https://github.com/MariaDB/server) code first.
+
+You can clone from github with
+
+	git clone git@github.com:MariaDB/server.git
+
+or if you are not a github user,
+
+	git clone https://github.com/MariaDB/server.git
+
+branch 10.5 was suggested despite the fact that develop branch of the engine will eventually work with 10.6
+
+	git checkout -b 10.5 origin/10.5
+
+MariaDB server contains many git submodules that need to be checked out with,
+
+	git submodule update --init --recursive --depth=1
+
+This would be automatically done when you excute cmake, but consider we are focus MCS here, so dependencies of MCS should be installed first.
+
+## Build Prerequisites
+
+The list of Debian or RPM packages dependencies can be installed with:
+
+	./install-deps.sh
+
+## Building phase
+
+After the dependencies had been installed, just follow the normal building instrutions to build, MCS will be compiled along with mariadbd.
+
+But for development convenience, we supply a script to build and run Mariadb server in MCS repo.
+
+	# TODO
