 ## Thrift interface description language
+
+For Thrift version 1.0.0.
+
 The Thrift interface definition language (IDL) allows for the definition of [Thrift Types](/docs/types). A Thrift IDL file is processed by the Thrift code generator to produce code for the various target languages to support the defined structs and services in the IDL file.
 
 ## Description
 
-*Under construction*
-
 Here is a description of the Thrift IDL.
 
 ## Document
@@ -35,32 +36,9 @@
 
 A namespace declares which namespaces/package/module/etc. the type definitions in this file will be declared in for the target languages. The namespace scope indicates which language the namespace applies to; a scope of '*' indicates that the namespace applies to all target languages.
 
-    [5]  Namespace       ::=  ( 'namespace' ( NamespaceScope Identifier ) |
-                                            ( 'smalltalk.category' STIdentifier ) |

-
-N.B.: Smalltalk has two distinct types of namespace commands:
-
-- smalltalk.prefix: Prepended to generated classnames.
-  - Smalltalk does not have namespaces for classes, so prefixes
-    are used to avoid class-name collisions.
-    Often, the prefix is the author's initials, like "KB" or "JWS",
-    or an abbreviation of the package name, like "MC" for "Monticello".
-- smalltalk.category: Determines the category for generated classes.
-  Any dots in the identifier will be replaced with hyphens when generating
-  the category name.
-  If not provided, defaults to "Generated-" + the program name.
-  Methods will not be categorized beyond "as yet uncategorized".
-  - Smalltalk allows filing both classes and methods within classes into named
-    groups. These named groups of methods are called categories.
-
-N.B.: The `php_namespace` directive will be deprecated at some point in the future in favor of the scoped syntax, but the scoped syntax is not yet supported for PHP.
-
-N.B.: The `xsd_namespace` directive has some purpose internal to Facebook but serves no purpose in Thrift itself. Use of this feature is strongly discouraged
