-#  aws-monitor
+# AWS Cost Monitoring Package
 
-A python package for monitoring AWS resources.
-
-## Features
-
-- Monitor AWS Cost By Period & Service, Linked Account
-- onitor AWS Cost  to monitor Service by Linked Account
-- Graphs
+This package provides tools for monitoring and analyzing AWS costs, both at the organizational level and individual account level. It includes functionality to get detailed cost breakdowns by linked accounts and AWS services, along with visualizations.
 
 ## Installation
 
+To install the package, use pip:
+
 ```bash
-pip install aws-monitor==0.4
+pip install aws-monitor
+```
+
+This will also install the following dependencies:
+
+- `boto3`
+- `matplotlib`
+
+## Usage
+
+### AWSOrgMonitor Class
+
+This class inherits from `AWSCostMonitor` and provides methods to fetch and analyze AWS cost data.
+
+#### Initialization
+
+```python
+from aws_monitoring.utils import AWSCostMonitor
+
+class AWSOrgMonitor(AWSCostMonitor):
+    def __init__(self):
+        super().__init__()
+```
+
+#### Get Cost
+
+Fetches the cost data within the specified time period and granularity.
+
+```python
+def get_cost(self, start: str, end: str, granularity: str, metrics: list, group_by: list = [], json=False) -> dict:
+```
+
+- **start**: Start date in `YYYY-MM-DD` format.
+- **end**: End date in `YYYY-MM-DD` format.
+- **granularity**: Granularity of the data (DAILY, MONTHLY).
+- **metrics**: List of metrics to fetch (e.g., ['UNBLENDED_COST']).
+- **group_by**: List of dimensions to group by.
+- **json**: Whether to return the response in JSON format.
+
+#### Get Billed Accounts
+
+Fetches the list of billed accounts within the specified time period.
+
+```python
+def get_billed_accounts(self, start: str, end: str) -> dict:
+```
+
+#### Get Cost Per Account
+
+Fetches the cost per account within the specified time period.
+
+```python
+def get_cost_per_account(self, start, end) -> dict:
+```
+
+#### Get Cost Per Account Graph
+
+Displays a bar graph of the cost per account within the specified time period.
+
+```python
+def get_cost_per_account_graph(self, start, end):
+```
+
+#### Get Cost Per Service
+
+Fetches the cost per AWS service within the specified time period and optionally for a specific linked account.
+
+```python
+def get_cost_per_service(self, start: str, end: str, linked_account: str = None) -> dict:
+```
+
+#### Get Cost Per Service Graph
+
+Displays a bar graph of the cost per AWS service within the specified time period and optionally for a specific linked account.
+
+```python
+def get_cost_per_service_graph(self, start: str, end: str, linked_account: str = None):
+```
+
+### Example Usage
+
+```python
+from aws_monitoring.utils import AWSOrgMonitor
+
+monitor = AWSOrgMonitor()
+start_date = '2023-06-01'
+end_date = '2023-06-30'
+
+# Get cost per service
+service_costs = monitor.get_cost_per_service(start_date, end_date)
+print(service_costs)
+
+# Visualize cost per service
+monitor.get_cost_per_service_graph(start_date, end_date)
+
+# Get cost per account
+account_costs = monitor.get_cost_per_account(start_date, end_date)
+print(account_costs)
+
+# Visualize cost per account
+monitor.get_cost_per_account_graph(start_date, end_date)
+```
