+    --train_dir=./train_dir --experiment=rl_course_vizdoom_health_gathering_supreme \
+    --save_video --video_frames=10000 --no_render
+```
+
+### Python API Usage
+```python
+from sample_factory.enjoy import enjoy
+from sample_factory.cfg.arguments import parse_full_cfg, parse_sf_args
+
+# Configure the environment
+env_name = "VizdoomHealthGathering-v0"
+cfg = parse_full_cfg(parse_sf_args([
+    "--algo=APPO",
+    f"--env={env_name}",
+    "--train_dir=./train_dir",
+    "--experiment=rl_course_vizdoom_health_gathering_supreme"
+]))
+
+# Run evaluation
+status = enjoy(cfg)
 ```
-python -m <path.to.enjoy.module> --algo=APPO --env=doom_health_gathering_supreme --train_dir=./train_dir --experiment=rl_course_vizdoom_health_gathering_supreme
+
+### Continue Training
+```bash
+python -m sample_factory.train --algo=APPO --env=VizdoomHealthGathering-v0 \
