+# Build
+
+## Supported platforms
+
+The following table lists TiDB support for common architectures and operating systems. 
+
+|Architecture|Operating System|Status|
+|------------|----------------|------|
+|AMD64|Linux Ubuntu (14.04+)|Stable|
+|AMD64|Linux CentOS (7+)|Stable|
+|AMD64|Mac OSX|Experimental|
+
+## Prerequisites
+
++ Go [1.5+](https://golang.org/doc/install)
++ Rust [nightly version](https://www.rust-lang.org/downloads.html)
++ GCC 4.8+ with static library
+
+The [check requirement script](../scripts/check_requirement.sh) can help you check prerequisites and 
+install the missing ones automatically.
+
+## Building and installing TiDB components
+
+You can use the [build script](../scripts/build.sh) to build and install TiDB components in the bin` directory.
