+## Inference
+
+You can find preliminary checkpoints at the following locations 
+
+Finetuned piano-only checkpoints (improved robustness):
+
+```
+large - https://storage.googleapis.com/aria-checkpoints/large-abs-inst.safetensors
+```
+
+Pretrained checkpoints:
+
+```
+large - https://storage.googleapis.com/aria-checkpoints/large-abs-pt.bin
+medium - https://storage.googleapis.com/aria-checkpoints/medium-abs-pt.bin
+small - https://storage.googleapis.com/aria-checkpoints/small-abs-pt.bin
+```
+
+You can then sample using the cli:
+
+```
+aria sample \
+    -m large \
+    -c <path-to-checkpoint> \
+    -p <path-to-midifile> \
+    -var <num-variations-to-generate> \
+    -trunc <seconds-in-to-truncate-prompt> \
+    -l <number-of-tokens-to-generate> \
+    -temp 0.95 \
+    -e
+```
+
+You can use `aria sample -h` to see a full list of options. If you wish to sample from a pretrained checkpoint, please use the `-pt` flag.
