 ### Use locally
 
+The simplest path — just type `alphadynamics` and answer the prompts:
+
 ```bash
 pip install alphadynamics
-alphadynamics predict --sequence AAAY --n-ensemble 16 --output traj.npz
+alphadynamics
+# Sequence (1-letter AA, e.g. AAAY): KLVFFAE
+# How many independent trajectories? [16]: <Enter>
+# How many timesteps per trajectory? [2500]: <Enter>
+# Device (cuda/cpu/auto) [auto]: <Enter>
+# Output file [...]: <Enter>
+# Save Ramachandran plot? [b=both, p=PNG, h=HTML, n=no] [b]: <Enter>
+```
+
+Or as a one-liner for power users:
+
+```bash
+alphadynamics predict --sequence AAAY --n-ensemble 16 --rollout-steps 2500 --plot --plot-html -o traj.npz
 ```
