-Initial README.md file for the geode-examples repository.
+# Apache Geode examples
 
-To be replaced right away by existing README.md file from the
-Apache Geode repository.
+This is the home of Apache Geode examples that are bundled with the project. Contributions<sup>[2]</sup> and corrections are welcome. Please talk to us about your suggestions at [dev@geode.apache.org](mailto:dev@geode.apache.org) or submit a [pull request](https://github.com/apache/geode/pull/new/develop).
+
+## Example requirements
+
+All examples:
+
+*  Need to be testable. Use unit tests, integration tests or whatever is applicable. Tests will run through the project's CI.
+*  Should be `Gradle` projects or part of existing ones. There may be exceptions here, but the community should have a consensus to accept.
+*  Have to follow code format & style from Apache Geode <sup>[1]</sup> guidelines.
+*  Should contain a `README.md` file with step-by-step instruction on how to set up and run the example. *Diagrams give you extra credit.*
+*  Donations need to be licensed through ASL 2.0 and contributors need to file an ICLA<sup>[3]</sup>.
+
+## Structure
+
+### Installation and a Tutorial for Beginners
+
+*  [How to Install](http://geode.apache.org/docs/guide/getting_started/installation/install_standalone.html)
+*  Set a `GEODE_HOME` environment variable to point to the root directory of the installation; this directory contains `bin/`. For those that have built from source, it will be the `geode-assembly/build/install/apache-geode` directory.
+*  If desired run the tutorial: [Apache Geode in 15 minutes or Less](http://geode.apache.org/docs/guide/getting_started/15_minute_quickstart_gfsh.html)
+
+### Basics
+
+*  [Replicated Region](replicated)
+*  Partitioned Region
+*  Persistence
+*  OQL (Querying)
+
+### Intermediate
+
+*  PDX & Serialization
+*  Lucene Indexing
+*  OQL Indexing
+*  Functions
+*  CacheLoader & CacheWriter
+*  Listeners
+*  Async Event Queues
+*  Continuous Querying
+*  Transactions
+*  Eviction
+*  Expiration
+*  Overflow
+*  Security
+*  Off-heap
+
+### Advanced
+
+*  WAN Gateway
+*  Durable subscriptions
+*  Delta propagation
+*  Network partition detection
+*  D-lock
+*  Compression
+*  Resource manager
+*  PDX Advanced
+
+### Use cases, integrations and external examples
+
+This section has self-contained little projects that illustrate a use case or an integration with other projects.
+
+*  SpringBoot Application
+*  HTTP Session replication
+*  Redis
+*  Memcached
+*  Spark Connector

+# Geode replicated region example
+
+This is one of the most basic examples. 
+Two servers host a replicated region.
+The producer puts 50 entries into the replicated region. The consumer prints the number of entries in the region.
+
+## Steps
+1. From the ```geode-examples/replicated``` directory, start the locator and two servers:
+
+        $ scripts/startAll.sh
+
+2. Run the producer:
+
+        $ gradle run -Pmain=Producer
+        ...
+        ... 
+        INFO: Done. Inserted 50 entries.
+
+3. Run the consumer:
+
+        $ gradle run -Pmain=Consumer
+        ...
+        ...
+        INFO: Done. 50 entries available on the server(s).
+
+4. Kill one of the servers:
+
+        $ gfsh
+        ...
+        gfsh>connect
+        gfsh>stop server --name=server1
+        gfsh>quit
+
+5. Run the consumer a second time, and notice that all the entries are still available due to replication: 
+
+        $ gradle run -Pmain=Consumer
+        ...
+        ...
+        INFO: Done. 50 entries available on the server(s).
+
+6. Shutdown the system:
+
+        $ scripts/stopAll.sh
+
+This example is a simple demonstration on basic APIs of Geode, as well how to write tests using mocks for Geode applications.
