+Solr example
+------------
+
+This directory contains Solr examples. Each example is contained in a 
+separate directory. To run a specific example, do:
+
+  bin/solr -e <EXAMPLE> where <EXAMPLE> is one of:
+  
+    cloud        : SolrCloud example
+    dih          : Data Import Handler (rdbms, mail, atom, tika)
+    schemaless   : Schema-less example (schema is inferred from data during indexing)
+    techproducts : Kitchen sink example providing comprehensive examples of Solr features
+
+For instance, if you want to run the Solr Data Import Handler example, do:
+
+  bin/solr -e dih
+  
+To see all the options available when starting Solr:
+
+  bin/solr start -help
+
+After starting a Solr example, direct your Web browser to:
+
+  http://localhost:8983/solr/
+
+To add documents to the index, use bin/post, for example:
+
+     bin/post -c techproducts example/exampledocs/*.xml
+
+(where "techproducts" is the Solr core name)
+

+Notes About These Examples
+--------------------------
+
+* References to Jar Files Outside This Directory *
+
+Various example SolrHome dirs contained in this directory may use "<lib>"
+statements in the solrconfig.xml file to reference plugin jars outside of 
+this directory for loading "contrib" plugins via relative paths.  
+
+If you make a copy of this example server and wish to use the 
+ExtractingRequestHandler (SolrCell), DataImportHandler (DIH), the 
+clustering component, or any other modules in "contrib", you will need to 
+copy the required jars or update the paths to those jars in your 
+solrconfig.xml.
+
+* Logging *
+
+By default, Jetty & Solr will log to the console and logs/solr.log. This can
+be convenient when first getting started, but eventually you will want to
+log just to a file. To configure logging, edit the log4j2.xml file in
+".../server/resources".
+It is also possible to setup log4j or other popular logging frameworks.
