 # rebuilding
 
+Running neko on the build.n script will rebuild the supported architectures on your current platform.
+
 ```
 cd project
-haxelib run hxcpp build.xml clean
-haxelib run hxcpp build.xml
+neko build.n clean
+neko build.n
 ```
 
+
 In the same folder, you can cross build to other platforms using the run.n with the said platform name.
 
 For example : 
 
 ```
-neko run.n android
+neko build.n android
+```
+
+You can save time if you know that you are only going to use, say, the dynamic libraries (ndlls) on a particular architecture on a particular platform.
+```
+neko build.n ndll-android-armv5
 ```
 
+You can enable debugging in the standard runtime libraries using the debug flag, eg:
+```
+neko build.n windows -debug
+```
+which may help with native debugging.  Don't forget to rebuild without debugging for release.
+
+
 For experts, you can configure the compilation scripts that will be used for executables and library production in the 'toolchain' folder.
