 ### GRASS GIS Scripts:
-First open GRASS and select/create Location
 
-1. This script will generate contours in Grass and also raster and vector maps
+1. First open GRASS and select/create Location
+
+2. Run contour.sh
+
+    ```bash contour.sh <DATA set for generating map> <File defining region for each map>```
+
+    This script will generate contours in Grass and also raster and vector maps
 for given set of data. Data set will be in CSV format `X|Y|Z` (You can refer
 example/GrassData.txt). We can define region of maps in CSV format in another
 CSV file containing only north, east, south, west values for given map. We can
 also divide the full map into small maps to increase the speed of execution or
 for many other purposes by providing more than one north, east, south, west
 values for each smaller map.  (You can refer example/DM1.txt)
-    * bash contour.sh \<DATA set for generating map> \<File defining region for each map>
-    *  e.g. `bash contour.sh example/GrassData.txt example/DM1.txt`
 
-2. This script will generate RL points on given polyline (in form of CSV file in format *X,Y*  you can refer to example/road.csv)
-    * bash road.sh \<Input file of points to generate profile > \<output file name>
+    *  e.g. ```bash contour.sh example/GrassData.txt example/DM1.txt```
+
+3. Run road.sh
+
+    ```bash road.sh <Input file of points to generate profile> <output file name> <Number of regions>```
+
+    This script will generate RL points on given polyline (in form of CSV file in format *X,Y*  you can refer to example/road.csv)
+
     * e.g.
-        `bash road.sh example/road.csv Final.txt`
+        ```bash road.sh example/road.csv Final.csv 6```
+
+    Process the output file to remove entries with `*` as RL value
+
+4. Run makeSection.sh
+
+    ```bash makeSection.sh <List of section points> <Number of regions>```
+
+    This script will generate RL points for given Sections (in form of CSV file generated by *TheRoad.py* you can refer to example/road.csv)
 
-3. This script will generate RL points given Sections (in form of CSV file generated by *TheRoad.py* you can refer to example/road.csv)
-    * bash makeSection.sh \<List of section points>
-    * e.g. `bash makeSection.sh example/section.csv`
+    * e.g. ```bash makeSection.sh section.csv 6```
 
 ### To get graph of output of TheRoad.py:
-* sage plot.sage \< inputFile.csv>
-* `sage plot.sage road.csv` 
+* ```sage plot.sage <inputFile.csv>```
+* ```sage plot.sage road.csv```
