+## Troubleshooting Setup Issues
+
+If you encounter issues while setting up the development environment, the following steps may help:
+
+### `make: command not found`
+Install `make` using:
+
+```bash
+sudo apt install make
+
+uv: command not found
+
+Install uv using:
+
+curl -LsSf https://astral.sh/uv/install.sh | sh
+source ~/.bashrc
+
+ruff: not found
+
+If linting fails due to a missing ruff command, install it with:
+
+uv tool install ruff
+
+WSL Path Recommendation
+
+When using WSL, it is recommended to clone the repository inside your Linux home directory (e.g., ~/hive) instead of under /mnt/c/... to avoid potential performance and permission issues.
