+# Number Conversion
+
+Short description of package/script
+
+- With this python script one can convert a user input number from one base to other.By Default conversion takes place from decimal to binary.Specify the FROM and TO parameters from the following:
+    -d->decimal,
+    -b->binary,
+    -x->hexadecimal,
+    -o->octal
+
+## Setup instructions
+
+- run the converter_script.py file in terminal
+
+## Output
+
+Display images/gifs/videos of output/result of your script so that users can visualize it
