+
+## Initialize the Compilation Environment of the CIX SDK
+
+Please execute the following commands in the root directory of the SDK to load the compilation tools and install the compilation dependencies:
+
+```bash
+sudo apt-get update
+. ./build-scripts/envtool.sh
+newer_env
+sudo apt-get install python-is-python3 7zip meson apt-utils
+```
+
+Only at this time can you execute the following commands to download and extract the additional binary resources:
+
+```bash
+i=$((1))
+get_cix_ext() {
+    local block="$(printf "%03d" $1)"
+    echo "https://github.com/radxa-pkg/cix-prebuilt/releases/download/$EX_CUSTOMER-$EX_PROJECT-$EX_VERSION/cix-sdk-ext.7z.$block"
+}
+while wget "$(get_cix_ext "$i")"; do
+    i=$((i + 1))
+done
+7zz x cix-sdk-ext.7z.001
+# Later system should use 7z instead of 7zz, as the command was renamed.
+# Optionally, remove the downloaded files:
+# rm cix-sdk-ext.7z.*
+```
+
+Now the system is ready for SDK compilation.
+
+## Common Commands and Compilation Targets
+
+The following commands can only be run after loading `envtoo.sh`:
+
+- `help`: Display the SDK command help.
+- `build radxa`: Compile all components and finally generate a runnable image.
+
+## Build Artifacts
+
+When the `build radxa` command is executed, you can find the following build artifacts:
+
+- `output/cix_evb/images/linux-fs.sdcard`: System image.
+- `output/cix_evb/images/cix_debian.iso`: The modified Debian installation ISO.
+- `output/cix_evb/images/cix_flash_all_O6.bin`: BIOS image.

+title: Obtain the Source Code
+sidebar_position: 0
+---
+
+With the authorization of CIX, Risha has released the publicly available part of the CIX SDK on GitLab. Users can conduct secondary development of the O6 through this SDK by themselves.
+
+:::info
+The CIX SDK only supports compilation on Debian 11 / Ubuntu 22.04 systems. The available storage space of the system should be at least 100GiB.
+
+When the SDK runs in a container, permission issues may occur. It is recommended to use a physical machine or a virtual machine for compilation.
+:::
+
+## Obtain the `repo` Tool
+
+The SDK provides a [manifest](https://gitlab.com/cix-linux/linux_repo/cix-manifest) that is compatible with the [`repo`](https://gerrit.googlesource.com/git-repo) tool to help users quickly restore the code file structure locally.
+
+Before downloading the SDK, users should first install this tool on the system they are using. For Debian systems, you can refer to the following commands:
+
+```bash
+sudo apt-get update
+sudo apt-get install repo
+```
+
+For reference on the usage of the `repo` command, please refer to the [`AOSP` documentation](https://source.android.com/docs/setup/reference/repo).
+
+## Pull the Code
+
+Please execute the following commands:
+
+```bash
+mkdir cix-sdk
+cd cix-sdk
+repo init https://gitlab.com/cix-linux/linux_repo/cix-manifest.git
+# Optionally, init with a specific version of manifest:
+# repo init -m release/<version>/default.xml https://gitlab.com/cix-linux/linux_repo/cix-manifest.git
+repo sync
+```
+
+After all the code has been downloaded, you can proceed with [software compilation](build).
