+### Set Custom Kedro Project Path
 
+You can specify a custom path to your Kedro project root directory in one of two ways:
+
+1. **Using the Command Palette**:
+   - Press `Cmd` + `Shift` + `P` (on macOS) or `Ctrl` + `Shift` + `P` (on Windows/Linux)
+   - Type and select `Kedro: Set Project Path`
+   - Enter the absolute path to your Kedro project root directory
+   - The extension will validate if it's a valid Kedro project by checking for `pyproject.toml`
+
+2. **Using Settings**:
+   - Open VS Code Settings (File > Preferences > Settings)
+   - Search for "Kedro Project Path"
+   - Enter the absolute path to your Kedro project root directory in the `kedro.kedroProjectPath` setting
+
+The extension will:
+- Validate that the provided path contains a valid Kedro project
+- Add the project folder to your workspace if it's not already included
+- Use this path as the root directory for all Kedro-related features
+
+**Note:** The project path must point to a directory containing a valid Kedro project with a `pyproject.toml` file that includes the `[tool.kedro]` section.
+
+Example:
+```
+{
+    "kedro.kedroProjectPath": "/absolute/path/to/your/kedro-project"
+}
+```

 Hit `Cmd` + `Shift` + `P` to open the VSCode command, look for `kedro: restart server` in case it's panic.
 
 ## Assumptions
-### Single Kedro Project
-The extension need to identify where is the Kedro project. It assumes the root of the workspace is a Kedro project, i.e. open the project where the `pyproject.toml` is.
 
 ### Configure Kedro Environment
 Currently, the extension assume the source of configuration is in the `base_env` defined by the config loader (if you didn't speficy, [usually it is `conf/base`](https://docs.kedro.org/en/stable/configuration/configuration_basics.html#configuration-loading)).
