 A RESTful web services API for DSpace, built using JAX-RS1 JERSEY.
 
 ##Getting Started
-This REST API is integrated directly into the DSpace code-base.
+This REST API is integrated directly into the DSpace codebase.
 
- * Rebuild as normal: mvn + ant
- * Deploy the webapp (i.e to tomcat)
-  * ```<Context path="/rest"  docBase="/dspace/webapps/rest"  allowLinking="true"/>```
+ * Rebuild as usual: mvn + ant
+ * Deploy the webapp (i.e to Tomcat)
+  * ```<Context path="/rest" docBase="/dspace/webapps/rest" />```
 
 
-At this point, this is a READ ONLY API for DSpace, for the anonymous user. Only Anonymous READ Communities, Collections, Items, and Bitstreams are available.
+REST API can do all CRUD (create, read, update, delete) operations over communities, collections, items, bitstream and bitstream policies. Without logging into the REST API, you have read access as an anonymous user (member of the Anonymous group). If you want to make changes in DSpace using the REST API, you must log into the API using the "login" endpoint and then use the returned token in request header of your subsequent API calls.
 
 ##Endpoints
