 # Nanospace-client
 
 ## Python client
+
 ### Requirement
 Request package is needed
 ```bash
+sudo apt install python3 python3-pip python-is-python3
 pip install requests
 ```
 
 ### Simple examle
-Check simple_example.py. Before try to launch it, think to change the login, password and srvUrl in the file.
-Think to end the address with a '/'.
+Check the `simple_example.py` python file. 
+
+Before try to launch it, change the `username`, `password` and `server` address (End the server address with a '/').
+
 ```python
 from nanospace import Nanospace
 
-nanospace = Nanospace('http://yourSrvUrl/','yourUsername', 'yourPassword')
+nanospace = Nanospace('http://server_address/','username', 'password')
 print(nanospace.get_string_value(66))
 nanospace.update_value(66, 'sma', '9000000')
-print(nanospace.get_string_value(66)) # 9000000
+print(nanospace.get_string_value(66)) # Should print 9000000
 
 print(nanospace.get_formula_value(66))
 nanospace.update_value(77, 'sma', '9000000')
-print(nanospace.get_formula_value(66)) # 9000000
+print(nanospace.get_formula_value(66)) # Should print 9000000
 ```
 
 ### Creation of element
-It is also possibile to create component, value, and modes from python. However, we advice to use the UI instead.

 nanospace._create_component(12, 'new_component)
 nanospace._create_mode(12, my_new_mode)
 nanospace._create_string_value(45, '')
 ```
 
-If the id is missing check the nanospace_ui url can help you to get one. 
-Then each one of the _create_ function are returning a python dictionary where you can find id.

+If the id is missing, check the Nanospace front-end url or the #id, that can help you to get one. 
+Then each one of the _create_ function are returning a Python dictionary where you can find id.
 
 ### Delete a element
 
-Even if it is advise to delete element from the UI we give also the possibilities to delete element from python.

  ```python
  # from nanospace import Nanospace
- # nanospace = Nanospace('http://yourSrvUrl/','yourUsername', 'yourPassword')
+ # nanospace = Nanospace('http://server_address/','username', 'password')
  nanospace._delete_component(12)
  nanospace._delete_mode(45)
  nanospace._delete_value(63)
  ```
 
-Note that __delete_value__ is working either if the value is a formula, or a string
