+# Compiling with LDB toolchain
+
+This document describes how to compile Doris using the LDB toolchain, which
will later replace the Docker development image as the default source code
compilation method for Doris.
+
+> Thanks to [Amos Bird](https://github.com/amosbird) for this contribution.
+
+## Prepare the environment
+
+This works for most Linux distributions (CentOS, Ubuntu, etc.).
+
+1. Download `ldb_toolchain_gen.sh`
+
+ The latest `ldb_toolchain_gen.sh` can be downloaded from
[here](https://github.com/amosbird/ldb_toolchain_gen/releases). This script is
used to generate the ldb toolchain.
+
+ > For more information, you can visit
[https://github.com/amosbird/ldb_toolchain_gen](https://github.com/amosbird/ldb_toolchain_gen)
+
+2. Execute the following command to generate the ldb toolchain
+
+ ```
+ sh ldb_toolchain_gen.sh /path/to/ldb_toolchain/
+ ```
+
+ where `/path/to/ldb_toolchain/` is the directory where the toolchain is
installed.
+
+ After successful execution, the following directory structure will be
created under `/path/to/ldb_toolchain/`.
+
+ ```
+ ├── bin
+ ├── include
+ ├── lib
+ ├── share
+ ├── test
+ └── usr
+ ```
+
+3. Download and install other compiled components
Review comment:
Do we need to mention other dependencies? `ldb_toolchain` provides flex.
However it's impossible to bundle autoconf, bison, etc. Here is a almost
minimal centos 6 Dockerfile to compile Doris with `ldb_toolchain`
