+This file contains instructions of how to extract BAL source release package and compile it.
+It is assumed that switch (Qumran) SDK is obtained from its relevant repository and it is not part of BAL source release package.
+
+Here are the steps needed to extract and compile the source code:
+
+1. Create a directory into which you want to extract the package. In the following steps we use /tmp/bal_src_release as an example.
+
+ mkdir -p /tmp/bal_src_release
+
+2. Unzip (extract) the combined Maple SDK and BAL package into the location you selected:
+
+ unzip <path_to_release_zip>/SW-BCM68620_<revision>.zip -d /tmp/bal_src_release
+
+3. Obtain switch (Qumran) SDK from its repository.
+
+4. Copy switch (Qumran) SDK to /tmp/bal_src_release/bal_release/3rdparty/bcm-sdk.
+
+ cp /<path_to_switch_sdk>/sdk-all-<revision>.tar.gz /tmp/bal_src_release/bal_release/3rdparty/bcm-sdk
+
+5. Change directory to the selected location.
+
+ cd /tmp/bal_src_release/bal_release
+
+6. Compile Maple SDK
+
+ make maple_sdk_dir
+ make maple_sdk
+
+7. Compile switch (Qumran) SDK
+
+ make ing_sdk_dir
+ make ing_sdk
+
+8. Compile BAL:
+
+ make core
+
+9. When the build ends successfully, bal_core executable (build/core/src/core/main/bal_core) should be created.
