+# Task Space Teleoperation — Setup & Run Guide
+
+## Prerequisites
+
+This script requires **Isaac Lab** to be installed and accessible at `/workspace/isaaclab`.
+
+---
+
+## Step 1: Fix Warp Version
+
+Isaac Sim requires `warp-lang==1.5.0`. Run this once to install the correct version:
+
+```bash
+/workspace/isaaclab/_isaac_sim/kit/python/bin/python3 -m pip install warp-lang==1.5.0
+```
+
+> **Why?** Isaac Sim bundles `omni.warp 1.5.0`, and newer versions of `warp-lang` removed APIs that Isaac Sim depends on (`warp.types.array`, `warp.context`). This will cause startup failures if not pinned correctly.
+
+---
+
+## Step 2: Run the Script
+
+From the `/workspace/isaaclab` directory, run:
+
+```bash
+cd /workspace/isaaclab
+./isaaclab.sh -p "final_repo/humanoid/autonomy/simulation/Teleop/keyboard-based teleoperation/task_space_test.py"
+```
+
+---
+
+## Notes
+
+- Always run from `/workspace/isaaclab` — the `./isaaclab.sh` script must be invoked from that directory.
+- Step 1 only needs to be run **once** per container session (or after a container rebuild).
+- If you see errors like `AttributeError: module 'warp.types' has no attribute 'array'`, repeat Step 1.
