-### Working with the Go Code
-
-> if you're not interested in building/contributing to the Go code, you can skip this section
-
-The Go code for Hiddify Next can be found in the `libcore` folder, as a [git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules) and in [core repository](https://github.com/hiddify/hiddify-next-core). The entrypoints for the desktop version are available in the [`libcore/custom`](https://github.com/hiddify/hiddify-next-core/tree/main/custom) folder and for the mobile version they can be found in the [`libcore/mobile`](https://github.com/hiddify/hiddify-next-core/tree/main/mobile) folder.
-
-For the desktop version, we have to compile the Go code into a C shared library. We are providing a Makefile to generate the C shared libraries for all operating systems. The following Make commands will build libcore and copy the resulting output in [`libcore/bin`](https://github.com/hiddify/hiddify-next-core/tree/main/bin):
-
-- `make windows-amd64`
-- `make linux-amd64`
-- `make macos-universal`
-
-For the mobile version, we are using the [`gomobile`](https://github.com/golang/go/wiki/Mobile) tools. The following Make commands will build libcore for Android and iOS and copy the resulting output in [`libcore/bin`](https://github.com/hiddify/hiddify-next-core/tree/main/bin):
-
-- `make android`
-- `make ios`
-
-### Working with the Flutter Code
 
 We recommend using [Visual Studio Code](https://docs.flutter.dev/development/tools/vs-code) extensions for development.
 
 #### Setting up the Environment
 
 We have extensive use of code generation in the form of [freezed](https://github.com/rrousselGit/freezed), [riverpod](https://github.com/rrousselGit/riverpod), etc. So it's generate these before running the code. Execute the following make commands in order:
-
-```shell
-# fetch dependencies
-$ make get
-
-# generate translations
-$ make translate
-
-# fetch geo assets
-$ make get-geo-assets
-
-# generate dart code using build_runner
-$ make gen
-```
-
 Assuming you have not built the `libcore` and want to use [existing releases](https://github.com/hiddify/hiddify-next-core/releases), you should run the following command (based on your target platform):
 
-- `make windows-libs`
-- `make linux-libs`
-- `make macos-libs`
-- `make android-libs`
-- `make ios-libs`
 
-If you want to build the `libcore` from source, prefix the above command with `build-` like `make build-windows-libs`.
+- `make windows-prepare`
+- `make linux-prepare` 
+- `make macos-prepare`
+- `make ios-prepare`
+- `make android-prepare`
+
+
+##### build the `libcore` from source (Optional)
+If you want to build the `libcore` from source after `make prepare`, use:
+- `make build-windows-libs`
+- `make build-linux-libs` 
+- `make build-macos-libs`
+- `make build-ios-libs`
+- `make build-android-libs`
