 ## Prerequisites
 
-Here is the list of required prerequisites.
+Use one top-level script to install all required dependencies and prepare WalletCore for building:
+
+```shell
+./bootstrap.sh all
+```
+
+Please note that the script configures the environment for all target platforms: Native, Android, iOS (on MacOS), and WASM.
+If you intend to use WalletCore on specific platforms only, you can specify those platforms in the arguments:
+
+```shell
+./bootstrap.sh android ios
+```
+
+Otherwise, consider installing the required prerequisites manually below.

 ## Full Build
 
-The full build can be triggered with one top-level script:
+WalletCore is ready to be built after installing all prerequisites.
+Building for each platform is different.
 
-```shell
-./bootstrap.sh
-```
+### Native building and testing
 
-Or, broken up in smaller steps:
+To build and run tests on the native platform (Linux, MacOS), run the following command:
 
 ```shell
-## Linux
-./tools/install-sys-dependencies-linux

-## MacOS
-./tools/install-sys-dependencies-mac

-./tools/install-dependencies
-./tools/install-rust-dependencies

 ```shell
-./build/tests/tests tests --gtest_filter=*

 If you'd rather use and IDE for building and debugging you can specify the `-G` option to cmake. For instance to use Xcode call `cmake -Bxcode -GXcode -DCMAKE_BUILD_TYPE=Debug` and use the generated project in the xcode folder.
