-Give a short description for your sample here. What does it do and why is it important?
+Sample code repo for Azure Cosmos DB Java SDK for SQL API. By cloning and running these samples, and then studying their implementations, you will have an example for sending various requests to Azure Cosmos DB from Java SDK via the SQL API.
 
 ## Contents
 
-Outline the file contents of the repository. It helps users navigate the codebase, build configuration and any related assets.

 ## Prerequisites
 
-Outline the required components and tools that a user might need to have on their machine in order to run the sample. This can be anything from frameworks, SDKs, OS versions or IDE releases.
+* Maven
+* Java SE JRE 8
+* Setting up an Azure Cosmos DB account through the Azure Portal. The **Create a database account** section of [this guide](https://docs.microsoft.com/en-us/azure/cosmos-db/create-sql-api-java) walks you through account creation. 
+* The hostname and master key for your Azure Cosmos DB account
 
 ## Setup
 
-Explain how to prepare the sample once the user clones or downloads the repository. The section should outline every step necessary to install dependencies and set up any settings (for example, API keys and output folders).
+Clone the sample to your PC. Using your Java IDE, open pom.xml as a Maven project.
 
 ## Running the sample
 
-Outline step-by-step instructions to execute the sample and see its output. Include steps for executing the sample from the IDE, starting specific services in the Azure portal or anything related to the overall launch of the code.
+These environment variables must be set
+
+```
+ACCOUNT_HOST=your account hostname;ACCOUNT_KEY=your account master key
+```
+
+in order to give the samples read/write access to your account.
+
+To run a sample, specify its Main Class 
+
+```
+com.azure.cosmos.examples.sample.synchronicity.MainClass
+```
+
+where *sample.synchronicity.MainClass* can be
+* crudquickstart.sync.SampleCRUDQuickstart
+* crudquickstart.async.SampleCRUDQuickstartAsync
+* indexmanagement.sync.SampleIndexManagement
+* indexmanagement.async.SampleIndexManagementAsync
+* storedprocedure.sync.SampleStoredProcedure
+* storedprocedure.async.SampleStoredProcedureAsync
+* changefeed.SampleChangeFeedProcessor *(Changefeed has only an async sample, no sync sample.)*
+
+*Build and execute from command line without an IDE:* From top-level directory of repo:
+```
+mvn clean package
+mvn exec:java -Dexec.mainClass="com.azure.cosmos.examples.sample.synchronicity.MainClass" -DACCOUNT_HOST=your account hostname -DACCOUNT_KEY=your account master key
+```
+
+where *sample.synchronicity.MainClass*, *your account hostname*, and *your account master key* are to be filled in as above. This will rebuild and run the selected sample.
 
 ## Key concepts
 
-Provide users with more context on the tools and services used in the sample. Explain some of the code that is being used and how services interact with each other.
+These samples cover a range of Azure Cosmos DB usage topics from more to less basic:
+* Basic management of databases, containers and items
+* Indexing, stored procedures
+* Change Feed
