+## Cloud Configuration
+Credentials default to authenticating to the Azure Active Directory endpoint for
+Azure Public Cloud. To access resources in other clouds, such as Azure Government
+or a private cloud, configure credentials with the `authority` argument.
+[AzureAuthorityHosts](https://aka.ms/azsdk/python/identity/docs#azure.identity.AzureAuthorityHosts)
+defines authorities for well-known clouds:
+```py
+from azure.identity import AzureAuthorityHosts
+
+DefaultAzureCredential(authority=AzureAuthorityHosts.AZURE_GOVERNMENT)
+```
+Not all credentials require this configuration. Credentials which authenticate
+through a development tool, such as `AzureCliCredential`, use that tool's
+configuration. Similarly, `VisualStudioCodeCredential` accepts an `authority`
+argument but defaults to the authority matching VS Code's "Azure: Cloud" setting.

 ### Features Added
 
 - Added additional `display_description` attribute to the `Metric` type.
+- Added a `MetricClass` enum to provide the class of a metric.
+- Added a `metric_class` attribute to the `MetricDefinition` type.
+- Added a `MetricNamespaceClassification` enum to support the `namespace_classification` attribute on `MetricNamespace` type.
+- Added a `MetricUnit` enum to describe the unit of the metric.
 
 ### Breaking Changes

 - `interval`  and `time_grain` are renamed to `granularity`
 - `orderby` is renamed to `order_by`
 - `LogsQueryResult` now returns `datetime` objects for a time values.
+- `LogsBatchQuery` doesn't accept a `request_id` anymore.
+- `MetricsMetadataValues` is removed. A dictionary is used instead.
+- `time_stamp` is renamed to `timestamp` in `MetricValue` type.
+- `AggregationType` is renamed to `MetricAggregationType`.
+- Removed `LogsBatchResultError` type.
+- `LogsQueryResultTable` is named to `LogsTable`
+- `LogsQueryResultColumn` is renamed to `LogsTableColumn`
+- `LogsTableColumn` is now removed. Column labels are strings instead.
+- `start_time` in `list_metric_namespaces` API is now a datetime.
+- The order of params in `LogsBatchQuery` is changed. Also, `headers` is no longer accepted.
+- `timespan` is now a required keyword-only argument in logs APIs.

+## Azure Monitor Query Champion Scenarios
+
+This document covers the basic champion Scenarios to use the package.
+
+### Authenticate the client
+
+Consider the following example, which creates and authenticates clients for both logs and metrics querying:
+
+```python
+from azure.identity import DefaultAzureCredential
+from azure.monitor.query import LogsQueryClient, MetricsQueryClient
+
+credential = DefaultAzureCredential()
+logs_client = LogsQueryClient(credential)
+metrics_client = MetricsQueryClient(credential)
+```
+
+### Make a simple query to the service
+
+* Each row is converted into a native python data type. For example, time is a datetime object instead of string.
+
+#### Results in tabular form
+
+```python
+import os
+import pandas as pd
+from datetime import timedelta
+from azure.monitor.query import LogsQueryClient
+from azure.identity import DefaultAzureCredential
+
+def query():
+    query = """AppRequests |
+    summarize avgRequestDuration=avg(DurationMs) by bin(TimeGenerated, 10m), _ResourceId"""
+
+    response = client.query(os.environ['LOG_WORKSPACE_ID'], query, 
+    timespan=timedelta(days=1))
+
+    if not response.tables:
+        return None
+
+    primary_table = response.tables[0]
+    df = pd.DataFrame(table.rows, columns=table.columns)

+# Azure Purview Account client library for Python
+
+Azure Purview Account is a fully managed cloud service.
+
+**Please rely heavily on the [service's documentation][account_product_documentation] and our [client docs][request_builders_and_client] to use this library**
+
+[Source code][source_code] |  [Package (PyPI)][account_pypi] | [API reference documentation][account_ref_docs]| [Product documentation][account_product_documentation]
+
+## Getting started
+
+### Prerequisites
+
+- Python 2.7, or 3.6 or later is required to use this package.
+- You must have an [Azure subscription][azure_subscription] and a [Purview][purview_resource] to use this package.
+
+#### Create a Purview Resource
+
+Follow [these][purview_resource] instructions to create your Purview resource
+
+### Install the package
+
+Install the Azure Purview Account client library for Python with [pip][pip]:
+
+```bash
+pip install azure-purview-account
+```
+
+### Authenticate the client
+
+To use an [Azure Active Directory (AAD) token credential][authenticate_with_token],
+provide an instance of the desired credential type obtained from the
+[azure-identity][azure_identity_credentials] library.
+
+To authenticate with AAD, you must first [pip][pip] install [`azure-identity`][azure_identity_pip] and
+[enable AAD authentication on your Purview resource][enable_aad]
+
+After setup, you can choose which type of [credential][azure_identity_credentials] from azure.identity to use.
+As an example, [DefaultAzureCredential][default_azure_credential]
+can be used to authenticate the client:
+
+Set the values of the client ID, tenant ID, and client secret of the AAD application as environment variables:
+AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET
+
+Use the returned token credential to authenticate the client:
+
+```python
+from azure.purview.account import PurviewAccountClient
+from azure.identity import DefaultAzureCredential
+
+credential = DefaultAzureCredential()
+client = PurviewAccountClient(endpoint="https://<my-account-name>.purview.azure.com", credential=credential)
+```
+
+## Key concepts
+
+### Client
+
+## Examples
+
+The following section shows you how to initialize and authenticate your client, then list all of your keys.
+
+- [Get Keys](#get-keys "Get All Keys")
+
+### Get Keys
+
+```python
+from azure.purview.account import PurviewAccountClient
+from azure.identity import DefaultAzureCredential
+
+credential = DefaultAzureCredential()
+client = PurviewAccountClient(endpoint="https://<my-account-name>.purview.azure.com", credential=credential)
+response = client.accounts.get_access_keys()
+print(response)
+```
+
+## Troubleshooting
+
+### General
+
+The Purview Account client will raise exceptions if status code of your responses is not defined.
+
+### Logging
+
+This library uses the standard
+[logging][python_logging] library for logging.
+Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO
+level.
+
+Detailed DEBUG level logging, including request/response bodies and unredacted
+headers, can be enabled on a client with the `logging_enable` keyword argument:
+
+```python
+import sys
+import logging
+from azure.identity import DefaultAzureCredential
+from azure.purview.account import PurviewAccountClient
+
+# Create a logger for the 'azure' SDK
+logger = logging.getLogger('azure')
+logger.setLevel(logging.DEBUG)
+
+# Configure a console output
+handler = logging.StreamHandler(stream=sys.stdout)
+logger.addHandler(handler)
+
+endpoint = "https://<my-account-name>.purview.azure.com"
+credential = DefaultAzureCredential()
+
+# This client will log detailed information about its HTTP sessions, at DEBUG level
+client = PurviewAccountClient(endpoint=endpoint, credential=credential, logging_enable=True)
+```
+
+Similarly, `logging_enable` can enable detailed logging for a single call,
+even when it isn't enabled for the client:
+
+```python
+result = client.accounts.get_access_keys(logging_enable=True)
+```
+
+## Next steps
+
+For more generic samples, see our [client docs][request_builders_and_client].

 To see how to use the Document Translation client library with Azure Storage Blob to upload documents, create SAS tokens
 for your containers, and download the finished translated documents, see this [sample][sample_translation_with_azure_blob].
 Note that you will need to install the [azure-storage-blob][azure_storage_blob] library to run this sample.
 
+## Advanced Topics
+
+The following section provides some insights for some of the advanced translation features such as glossaries and custom translation models.
+
+### **Glossaries**
+Glossaries are domain-specific dictionaries. For example, if you want to translate some medical-related documents, you may need support for the many words, terminology, and idioms in the medical field which you can't find in the standard translation dictionary or you simply need specific translation. This is why Document Translation provides support for glossaries. 
+
+#### **How To Create Glossary File**
+
+Document Translation supports glossaries in the following formats:
+
+|**File Type**|**Extension**|**Description**|**Samples**|
+|---------------|---------------|---------------|---------------|
+|Tab-Separated Values/TAB|.tsv, .tab|Read more on [wikipedia][tsv_files_wikipedia]|[glossary_sample.tsv][sample_tsv_file]|
+|Comma-Seperated Values|.csv|Read more on [wikipedia][csv_files_wikipedia]|[glossary_sample.csv][sample_csv_file]|
+|Localization Interchange File Format|.xlf, .xliff|Read more on [wikipedia][xlf_files_wikipedia]|[glossary_sample.xlf][sample_xlf_file]|
+
+View all supported formats [here][supported_glossary_formats].
+
+#### **How Use Glossaries in Document Translation**
+In order to use glossaries with Document Translation, you first need to upload your glossaries file to some blob container, and then provide the SaS url to of this glossary file to Document Translation as in the code samples [sample_translation_with_glossaries.py][sample_translation_with_glossaries].
+
+
+### **Custom Translation Models**
+Instead of using Document Translation's engine for translation, you can use your own custom Azure machine/deep learning model.
+ 
+#### **How To Create a Custom Translation Model**
+For more info on how to create, provision, and deploy your own custom Azure translation model, please follow the instructions here: [Build, deploy, and use a custom model for translation][custom_translation_article]
+
+#### **How To Use a Custom Translation Model With Document Translation**
+In order to use a custom translation model with Document Translation, you first 
+need to create and deploy your model, then follow the code sample [sample_translation_with_custom_model.py][sample_translation_with_custom_model] to use with Document Translation.
