 //===----------------------------------------------------------------------===//
 
 Flang depends on a fork of clang for some of its files. In order to compile
-Flang, you'll need to merge the clang branch and flang branch together in your
-local repository. Please use the following two commands to achieve this:
-
+Flang, you'll need to fetch the clang_branch and merge it with master in your
+local repository. After cloning flang, you can use the following commands to achieve
+this:
+  
+  git fetch origin clang_branch
+  git checkout clang_branch
+  git checkout master
   git merge --squash --no-commit clang_branch
   git reset HEAD

+
+Flang's driver will instruct the linker to link with the libflang runtime. 
+You can get libflang at https://github.com/hyp/libflang . Once you have libflang, 
+you'll need to tell flang where it is - you can use the -L option (e.g. -L~/libflang).

 Short term:
 
 * Fix lexing bugs
+  - Fixed form for numerical literals (i.e. ignore whitespace)
   - Continuations in BOZ literals
   - Others
 * 'INCLUDE' which search for files in the directory of the current file first.
 * Full parsing of statements
-* Clang-style diagnostics
-  - Warnings and notes
-  - Ranges for errors (i.e. ^~~~~~ )
-* Testing infrastructure
 
 Long term:
 
 * Flang driver (?)
 * Parsing GNU modules
-* Sema
-* Code generation
-* Builtin functions
 
 Longer term:
 
-* Fortran77 support
+* Fortran90/95 support
+* IO support.
