 This library will not be used for storing data entries (such as formats or datalines).  Where this becomes necessary in the future, a new repo will be created, in order to keep the NPM bundle size down (for the benefit of those looking to embed purely macros in their applications).
 
-### FCMP library (All Platforms)
+### FCMP folder (All Platforms)
 
 - Function and macro names are identical, except for special cases
 - Prefixes: _mcf_
 
 The fcmp macros are used to generate fcmp functions, and can be used with or without the `proc fcmp` wrapper.
 
-### META library (SAS9 only)
-
-Macros used in SAS EBI, which connect to the metadata server.
-
-- OS independent
-- Metadata aware
-- No X command
-- Prefixes: _mm_
-
-### SERVER library (@sasjs/server only)
-These macros are used for building applications using [@sasjs/server](https://server.sasjs.io) - an open source REST API for Desktop SAS.
-
-- OS independent
-- @sasjs/server aware
-- No X command
-- Prefixes: _ms_
-
-### VIYA library (Viya only)
-
-Macros used for interfacing with SAS Viya.
-
-- OS independent
-- No X command
-- Prefixes: _mv_, _mvf_
-
-### METAX library (SAS9 only)
-
-- OS specific
-- Metadata aware
-- X command enabled
-- Prefixes: _mmw_,_mmu_,_mmx_

 ### LUA library
 
 Wait - this is a macro library - what is LUA doing here?  Well, it is a little known fact that you CAN run LUA within a SAS Macro.  It has to be written to a text file with a `.lua` extension, from where you can `%include` it.  So, without using the `proc lua` wrapper.

 ## Installation
 
 First, download the repo to a location your SAS system can access. Then update your sasautos path to include the components you wish to have available, eg:
 
 ```sas
-options insert=(sasautos="/your/path/macrocore/base");
-options insert=(sasautos="/your/path/macrocore/meta");
+%let repoloc=/your/path/core;
+options insert=(sasautos="&repoloc/base");
+options insert=(sasautos="&repoloc/ddl");
+options insert=(sasautos="&repoloc/fcmp");
+options insert=(sasautos="&repoloc/lua");
+options insert=(sasautos="&repoloc/meta");
+options insert=(sasautos="&repoloc/metax");
+options insert=(sasautos="&repoloc/server");
+options insert=(sasautos="&repoloc/viya");
+options insert=(sasautos="&repoloc/xplatform");
 ```
 
 The above can be done directly in your sas program, via an autoexec, or an initialisation program.
