+1. Make sure the project you're going to add has a top-level `buildAll` Gradle task.
+
+   See the build script of [Hello Example](https://github.com/spine-examples/hello/blob/master/build.gradle)
+   for the declaration of such a task. This task must be present in both single- 
+   and multi-module Gradle example projects that are going to be used for

+   Please make sure the new submodule goes under the `_code/examples` directory, as shown in

+   file.
+4. Insert code embedding directives where needed in the `docs/content/` folder.
+5. Navigate to the `_code` directory.
+6. Execute: `./embed-code -config-path="config-of-your-choice.yml" -mode="embed"`.
 
    For example:
    ```shell
    ./embed-code-macos -config-path="config-v1.yml" -mode="embed"
    ```
 
+### Adding a new small piece
+
+1. Add the code under `_code/samples/src` directory.
+2. Make sure tests for the new code pass.
+3. Add the new piece using the [`embed-code` guide][embed-code-readme].
+4. Include the build of the added project into the [`settings.gradle.kts`](settings.gradle.kts)
