 Atlas is a ECMWF framework for parallel data-structures supporting unstructured
 grids and function spaces, with the aim to investigate alternative more scalable
-dynamical core options for IFS, and to create modern interpolation and product
-generation softrware
+dynamical core options for Earth System models, and to support modern interpolation
+and product generation softrware
 
 Atlas is predominantly C++ code, with main features available to Fortran codes
 through a F2003 interface. It requires some flavour of Unix (such as Linux).
 It is known to run on a number of systems, some of which are directly supported
 by ECMWF.

 Third Party Requirements

 Requirements to compile atlas:
 
 - CMake --- For use and installation see http://www.cmake.org/
-- ecbuild
+- ecbuild --- ECMWF library of CMake macros
 - eckit (with mpi support)
-- python (only when Fortran bindings are required)
 
 Recommended:
 
-- OpenMP --- Shared memory parallelisation
-- fkit --- Unit testing for Fortran
+- fckit --- For enabling Fortran interfaces
+- python (only when Fortran bindings are required)
+
+Optional for certain features:
 
+- gridtools-storage --- For GPU interoperability
+- transi --- For enabling IFS spherical harmonics transforms ( not open-source )
+- CGAL --- For enabling Delaunay triangulation of unstructured grids
 
 Installation
 ------------
 
 Atlas employs an out-of-source build/install based on CMake.
 
+Make sure ecbuild, eckit and fckit are installed and the ecbuild
+executable script is found ( `which ecbuild` ):
+
+```bash
+# For finding eckit
+ECKIT_PATH               # Path to eckit prefix
+
+# For finding fckit
+FCKIT_PATH               # Path to fckit prefix
+```
+
+Other environment variables that could be required for optional features:
+
+```bash
+# For finding gridtools-storage
+GRIDTOOLS_STORAGE_PATH   # Path to gridtools-storage prefix
+
+# For finding transi
+TRANSI_PATH              # Path to transi prefix
+
+# For finding CGAL
+BOOST_ROOT               # Path to Boost prefix
+CGAL_DIR                 # Path to directory containing CGALConfig.cmake
+```
+
+Now proceed with installation as follows
+
 ```bash
 # Environment --- Edit as needed
 ATLAS_SRC=$(pwd)
 ATLAS_BUILD=build
 ATLAS_INSTALL=$HOME/local
-export CC=mpicc
-export CXX=mpicxx
 
 # 1. Create the build directory:
 mkdir $ATLAS_BUILD
 cd $ATLAS_BUILD
 
 # 2. Run CMake
-cmake $ATLAS_SRC -DCMAKE_INSTALL_PREFIX=$ATLAS_INSTALL
+ecbuild --prefix=$ATLAS_INSTALL -- $ATLAS_SRC
 
 # 3. Compile / Install
 make -j10
 make install
+
+# 4. Check installation
+$ATLAS_INSTALL/bin/atlas --info
 ```
 
 Extra flags maybe added to step 2 to fine-tune configuration.

 > **Note:**
 > By default compilation is done using shared libraries. Some systems have linking
 > problems with static libraries that have not been compiled with `-fPIC`.
 > In this case, also compile atlas using static linking, by adding to step 2:
-    `-DBUILD_SHARED_LIBS=OFF`
+    `--static`
 
 Runtime Configuration
 ---------------------
 
-Atlas behaviour can be configured through variables defined at the command-line, in the
-environment, or in configuration files.
-In following table, the column "variable" can be edited in configuration files.
-
-| variable                    | command line     | environment              | default            |
-|-----------------------------|------------------|--------------------------|--------------------|
-| `debug`                     | `--debug`        | `$DEBUG`                 | `0`                |
-|                             | `--name`         |                          | `<app>`            |
-| `atlas.logfile`             | `--logfile`      | `$ATLAS_LOGFILE`         |                    |

Subject: [PATCH 281/355] ATLAS-135 transformation with multiple vorticity,
 divergence and/or scalar fields works now. test_trans_vordiv_with_translib
 works again correctly. Currently no known issues.
