 # Introduction 
-This repository contains the codes for the Geo-INQUIRE tool to compute the rainfall-induced landslide hazard over an area. This verison of the code assumes a constant 24-h rainfall acummulation over the entire area covered by the susceptibility map.
+This repository contains the codes for the Geo-INQUIRE tool to compute the rainfall-induced landslide hazard over an area. This verison of the code can assume a constant 24-h rainfall acummulation over the entire area covered by the susceptibility map, or use a user-provided map with the 24h rainfall acummulations over the area covered by the susceptibility map.
 
 # Getting Started
 1.	Installation process: The landslide hazard tool requires to have installed python and Poetry.
 2.	Software dependencies: Python version and dependecies are specified in the Poetry .toml file. 
 
 ## REQUIRED INPUT DATA AND FILES:
 Input files must be saved (before running the hazard tool) in the ../Data/ folder:
-        - `input_variables.csv`: csv file where input rainfall can be specified.
+        - `input_variables.csv`: csv file where the mode and input rainfall can be specified.
         - `*_sus.tif` : Tile of the susceptibility map over hazard will be computed. Must be downloaded from map repository.
         - `StdMaxDayRain.txt`: Standard deviation of the maximum daily rainfall.
 
 ## RUN THE HAZARD TOOL:
-1. In place the tile of the susceptibiluty map covering the area you want to compute the hazard in the folder `./Tool-Hazard-Map/input`
-2. Modify the `input_variables.csv` excel with the 24 h rainfall acummulation in [mm] you want to check.
-2. The code you need to runn is stored in `./Tool-Hazard-Map/Code` folder
-3. Before you runn the code make sure you have activated the poetry enviroment: `poetry shell`
-4. From the `./Tool-Hazard-Map/Code` folder in the terminal run: `python Hazard.py`
-5. The outpurs are stored in the `../Results/constant/` folder.
+1. In place the tile of the susceptibiluty map covering the area you want to compute the hazard in the folder `./Tool-Hazard-Map/input`.
+2. In the case of wanting to use a spatial-variable rainfall map place it in the folder the folder `./Tool-Hazard-Map/input`. The map needs to be in ".tif" format, cover the area of the susceptibility map and use the WGS84 (EPSG: 4326) projection.
+3. Modify the `input_variables.csv` excel:
+        3.3. Select mode;  "constant" if you desire to apply a constat user-specified rainfall acummulation over an area. "map" if you desire to use your own rainfall map.
+        3.4. In case of using the mode "constant" specify the 24 h rainfall acummulation in [mm] over the area.
+        3.5. In case of using teh mode "map" specify the name of the .tif file containing the rainfall map (without the file extension).
+
+5. The code you need to runn is stored in `./Tool-Hazard-Map/Code` folder
+6. Before you runn the code make sure you have activated the poetry enviroment: `poetry shell`
+7. From the `./Tool-Hazard-Map/Code` folder in the terminal run: `python Hazard.py`
+8. The outpurs are stored in the `../Results/constant/` folder.
 
 ## OUTPUT:
 Results from the Hazard Tool are saved in the following folder which is authomatically generated `../Results/constant/`
