 This is the Pytorch implementation of our ICCV2023 paper [SIRA-PCR](./files/final_version.pdf).
 
-Our code and dataset will be released soon.
+## Data Preparation
+Our dataset will be released soon.
+
+## Pre-trained Weights
+Our pre-trained weights will be released soon.
+
+## Training
+### Training on synthetic data
+Use the following command for training on FlyingShapes.
+
+```
+CUDA_VISIBLE_DEVICES=GPUS python train.py --model_dir=./experiment/experiment_geotransformer/train_on_FlyingShapes/
+```
+
+Use the following command for training on FlyingShapes and Structured3D.
+
+```
+CUDA_VISIBLE_DEVICES=GPUS python train.py --model_dir=./experiment/experiment_geotransformer/train_on_FlyingShapes_Structured3D/
+```
+
+Or use the following command to start from pre-trained weights.
+
+```
+CUDA_VISIBLE_DEVICES=GPUS python train.py --model_dir=./experiment/experiment_geotransformer/train_on_FlyingShapes_Structured3D/ --resume=./weights/model_best_trained_on_flyingshapes.pth -ow
+```
+
+### Fine-tuning on SIRA
+Use the following command for fine-tuning on SIRA.
+
+```
+CUDA_VISIBLE_DEVICES=GPUS python train.py --model_dir=./experiment/experiment_geotransformer/finetune_on_SIRA/ --resume=./weights/model_best_trained_on_flyingshapes_structured3d.pth -ow
+```
+### Fine-tuning on 3DMatch
+Use the following command for fine-tuning on 3DMatch.
+
+```
+CUDA_VISIBLE_DEVICES=GPUS python train.py --model_dir=./experiment/experiment_geotransformer/finetune_on_3DMatch/ --resume=./weights/model_best_trained_on_flyingshapes_structured3d.pth -ow
+```
+
+## Testing
+### Testing on 3DMatch/3DLoMatch
+```
+# 3DMatch
+CUDA_VISIBLE_DEVICES=0 python test.py --model_dir=./experiment/experiment_geotransformer/finetune_on_3DMatch/ --resume=./weights/model_best_finetuned_on_3dmatch.pth --benchmark=3DMatch
+CUDA_VISIBLE_DEVICES=0 python eval.py --model_dir=./experiment/experiment_geotransformer/finetune_on_3DMatch/ --benchmark=3DMatch --method=lgr
+
+# 3DLoMatch
+CUDA_VISIBLE_DEVICES=0 python test.py --model_dir=./experiment/experiment_geotransformer/finetune_on_3DMatch/ --resume=./weights/model_best_finetuned_on_3dmatch.pth --benchmark=3DLoMatch
+CUDA_VISIBLE_DEVICES=0 python eval.py --model_dir=./experiment/experiment_geotransformer/finetune_on_3DMatch/ --benchmark=3DLoMatch --method=lgr
+```
+
+### Testing on ETH
+```
+CUDA_VISIBLE_DEVICES=0 python test.py --model_dir=./experiment/experiment_geotransformer/test_on_ETH/ --resume=./weights/model_best_finetuned_on_3dmatch.pth --benchmark=ETH
+CUDA_VISIBLE_DEVICES=0 python eval.py --model_dir=./experiment/experiment_geotransformer/test_on_ETH/ --benchmark=ETH --method=lgr
+```
