+# Building System Input Actions Setup
+
+## Required Input Actions
+
+Add these three actions to your `InputSystem_Actions.inputactions` file in the **Player** action map:
+
+### 1. ToggleBuildMode (Button)
+- **Action Type**: Button
+- **Control Type**: Button
+- **Binding**: Keyboard B
+
+### 2. Rotate (Value)
+- **Action Type**: Value
+- **Control Type**: Axis
+- **Binding**: Keyboard R (positive value)
+- Alternative: You can use a 1D Axis composite with:
+  - Negative: Q
+  - Positive: E
+
+### 3. Build (Button)
+- **Action Type**: Button
+- **Control Type**: Button
+- **Binding**: Mouse Left Button
+
+## Step-by-Step Setup in Unity
+
+1. **Open Input Actions Asset**
+   - Navigate to `Assets/InputSystem_Actions.inputactions`
+   - Double-click to open the Input Actions window
+
+2. **Select Player Action Map**
+   - In the left panel, click on "Player" action map
+
+3. **Add ToggleBuildMode Action**
+   - Click the "+" button in the Actions column
+   - Name it: `ToggleBuildMode`
+   - Action Type: Button
+   - Add binding: Keyboard → B
+
+4. **Add Rotate Action**
+   - Click the "+" button in the Actions column
+   - Name it: `Rotate`
+   - Action Type: Value
+   - Control Type: Axis
+
+   **Option A (Simple - Single key):**
+   - Add binding: Keyboard → R
+
+   **Option B (Advanced - Q/E rotation):**
+   - Right-click → Add 1D Axis Composite
+   - Negative: Keyboard → Q
+   - Positive: Keyboard → E
+
+5. **Add Build Action**
+   - Click the "+" button in the Actions column
+   - Name it: `Build`
+   - Action Type: Button
+   - Add binding: Mouse → Left Button
+
+6. **Save and Regenerate**
+   - Click "Save Asset" button
+   - The `InputSystem_Actions.cs` script will auto-regenerate
+
+## How It Works in Code
+
+The BuildingPlacement script subscribes to these actions:
+
+```csharp
+// Setup in OnNetworkSpawn
+_inputActions.Player.ToggleBuildMode.performed += OnToggleBuildMode;
+_inputActions.Player.Rotate.performed += OnRotate;
+_inputActions.Player.Build.performed += OnBuild;
+
+// Cleanup in OnNetworkDespawn
+_inputActions.Player.ToggleBuildMode.performed -= OnToggleBuildMode;
+_inputActions.Player.Rotate.performed -= OnRotate;
+_inputActions.Player.Build.performed -= OnBuild;
+```
+
+### ToggleBuildMode
+- Triggers when B is pressed
+- Toggles build mode on/off
+- Shows/hides building preview
+
+### Rotate
+- Triggers when R is pressed (or Q/E if using composite)
+- Reads value: positive = rotate right, negative = rotate left
+- Rotates building preview by 90°
+
+### Build
+- Triggers when left mouse button is pressed
+- Only works when build mode is active
+- Places the building at the preview position
+
+## Customizing Controls
+
+To change the key bindings:
+1. Open `InputSystem_Actions.inputactions`
+2. Click on the binding you want to change
+3. Click "Path" dropdown
+4. Select new key/button
+5. Save Asset
+
+No code changes needed - the script uses the action names, not specific keys!
+
+## Testing
+
+After setup:
+1. Enter Play mode
+2. Press **B** → Should see "Entered Build Mode" in console
+3. Press **R** → Building preview should rotate
+4. Click **Left Mouse Button** → Should place building (if valid position)
+5. Press **B** again → Should exit build mode
+
+## Troubleshooting
+
+**Error: "ToggleBuildMode does not exist"**
+- Make sure you named the action exactly `ToggleBuildMode` (case-sensitive)
+- Save the Input Actions asset to regenerate the code
+
+**Rotation doesn't work:**
+- Check the action name is exactly `Rotate`
+- If using composite, make sure it's a 1D Axis composite
+- Verify the action type is "Value" not "Button"
+
+**Build action triggers during movement:**
+- Make sure Build action is mapped to Mouse Left Button, not Attack
+- Check that Build mode is active (press B first)
