 ## Guide
 
+### Cloning from git
+
+Ensure you clone the repository including the submodules! For example:
+
+```bash
+git clone --recurse-submodules -j8 https://github.com/ByteWelder/Tactility.git
+```
+
 ### Build environment setup
 
 Ensure you have [esp-idf 5.1.2](https://docs.espressif.com/projects/esp-idf/en/v5.1.2/esp32/get-started/index.html) installed, then select the correct device:
