+## relu_main.py 
+The relu_main script is used to run and log sparsity collection and optimiser for different relu tuning policies
+
+### Notes
+Assumes the existence of a the following directories:
+- ./runlog
+- ./runlog/<arch-name<
+- ./relu_thresholds
+- ./relu_thresholds/<arch-name<
+- ./relu_thresholds
+- ./relu_thresholds/<arch-name<
+- ../../fpgaconvnet-optimiser/fpgaconvnet/optimiser/<arch-name<
+
+Uses the krish-skipping branches of fpgaconvnet-optimiser and fpgaconvnet-model
+
+
+### Usage
+'''
+python relu_main.py
+'''
+
+### Flags
+- **arch**: model_name
+- **relu-policy**: relu policy choice between slowest_node and uniform 
+- **fixed-hardware**: Uses fixed-hardware and does not run optimiser. Must provide "platform_path", and "optimised_config_path" flags to load fixed hardware
+- **normalise-hardware**: Runs optimiser on same DSPs for dense and no skipping windows
+- **accuracy_path**: "model_path". For fixed hardware
+- **model_path**: Path to sparse .onnx model. 
+- **platform_path**: Path to platform specs (.toml). For fixed hardware
+- **gpu**
+- **enable-wandb**
+
+### Parameters you may want to vary
+- **THRESHOLD_INC in relu_main.py**: Amount you want to increase ReLU by for each iteration
+- **--gain flag in fpgaconvnet-optimiser cli**: Minimum gain to push fine
