 This configuration requires the installation of :
 
     - the GNU =global= package (for gtags)
-    - =clang= (for ivory)
-    - =cmake= (for ivory)
+    - ccls language server (for LSP functionality)
     - =llvm-libs= (for cmake, somehow not a dependency on Manjaro when installing cmake)
     - Use python-pip to install requirements for elpy:
       =pip install jedi flake8 importmagic autopep8 yapf=
     - =ditaa= (for ascii to image generation in org-mode)
 
-When first checking out this config, run =irony-install-server= to make and install the irony-server.
