+## 4. Workflow: Compiling & Installing Apps
+
+### Step 1: Source Environment & Path
+Ensure ESP-IDF environment is sourced and export local SDK path:
+```bash
+. /Users/adolforeyna/esp/esp-idf/export.sh
+export TACTILITY_SDK_PATH=/Users/adolforeyna/.gemini/antigravity/scratch/tactility/release/TactilitySDK
+```
+
+### Step 2: Compile the App
+Run the Tactility build script, specifying the target platform:
+```bash
+# Compile and package HelloWorld
+python3 tactility.py Apps/HelloWorld build esp32s3 --local-sdk
