+# Locating Model Parameters for updating
+
+The model parameters are located in [input folder under pybamm ./pybamm/input/parameters/lithium_ion](../pybamm/input/parameters/lithium_ion/)
+
+The folders for parameters are further divided into `cells`, `electrolytes`, `negative_electrodes`, `positive_electrodes` and `separators`
+
+Under these folders, each parameter set has its own folder. The parameter set which we will be updating is called `UMBL_Siegel2022`
+
+## Cell
+Overall cell related parameters like nominal capacity, electrode thickness, current collector properties etc. are located in the cells folder [../pybamm/input/parameters/lithium_ion/cells/UMBL_Siegel2022/](../pybamm/input/parameters/lithium_ion/cells/UMBL_Siegel2022/)
+
+Find [parameters.csv](../pybamm/input/parameters/lithium_ion/cells/UMBL_Siegel2022/parameters.csv) file in this folder and update the file with the new parameters.
+
+## Electrolyte
+Electrolyte related parameters are located in the electolytes folder [../pybamm/input/parameters/lithium_ion/electrolytes/UMBL_Siegel2022/](../pybamm/input/parameters/lithium_ion/electrolytes/LiPF6_Siegel2022/)
+
+Find [parameters.csv](../pybamm/input/parameters/lithium_ion/electrolytes/LiPF6_Siegel2022/parameters.csv) file in this folder and update the file with the new parameters.
+
+Additionally, the [conductivity](../pybamm/input/parameters/lithium_ion/electrolytes/LiPF6_Siegel2022/electrolyte_conductivity_Siegel.py) and [diffusivity](../pybamm/input/parameters/lithium_ion/electrolytes/LiPF6_Siegel2022/electrolyte_diffusivity_Siegel.py) functions are located in separate python files. Update them separately.
+
+## Negative electrode
+Negative electrode related parameters are located here [../pybamm/input/parameters/lithium_ion/negative_electrodes/graphite_UMBL_Siegel2022/](../pybamm/input/parameters/lithium_ion/negative_electrodes/graphite_UMBL_Siegel2022/)
+
+Update these files in the folder
+- `parameters.csv`
+- `graphite_ocp_Siegel.py`
+- `graphite_diffusivity_Siegel.py`
+- `graphite_electrolyte_exchange_current_density_Siegel.py`
+- `graphite_electrolyte_entropic_change_density_Siegel.py`
+
+## Positive electrode
+Positive electrode related parameters are located here [../pybamm/input/parameters/lithium_ion/positive_electrodes/NMC_UMBL_Siegel2022/](../pybamm/input/parameters/lithium_ion/positive_electrodes/NMC_UMBL_Siegel2022/)
+
+Update these files in the folder
+- `parameters.csv`
+- `NMC_ocp_Siegel.py`
+- `NMC_diffusivity_Siegel.py`
+- `NMC_electrolyte_exchange_current_density_Siegel.py`
+- `NMC_electrolyte_entropic_change_density_Siegel.py`
+
+## Separator
+Separator related parameters are located here [../pybamm/input/parameters/lithium_ion/separators/separator_Siegel2022/](../pybamm/input/parameters/lithium_ion/separators/separator_Siegel2022/)
+
+Find [parameters.csv](../pybamm/input/parameters/lithium_ion/separators/separator_Siegel2022/parameters.csv) file in this folder and update the file with the new parameters.
