+* Description
+This layer provides basic syntax highlighting and formatting as provided by 
+[[https://github.com/mgyucht/jsonnet-mode][jsonnet-mode]]
+
+* Install
+To use this configuration layer, add it to your =~/.spacemacs=. You will need to
+add =jsonnet= to the existing =dotspacemacs-configuration-layers= list in this
+file.
+
+To use some of the additional formatting and evaluation features, you'll need
+to [[http://jsonnet.org/index.html][the jsonnet binary]]

+;; Briefly, each package to be installed or configured by this layer should be
+;; added to `jsonnet-packages'. Then, for each package PACKAGE:
+;;
+;; - If PACKAGE is not referenced by any other Spacemacs layer, define a
+;;   function `jsonnet/init-PACKAGE' to load and initialize the package.
+
+;; - Otherwise, PACKAGE is already referenced by another Spacemacs layer, so
+;;   define the functions `jsonnet/pre-init-PACKAGE' and/or
+;;   `jsonnet/post-init-PACKAGE' to customize the package as it is loaded.
+
+;;; Code:
+
+(setq jsonnet-packages
+  '(
+    jsonnet-mode

+
+   "The list of Lisp packages required by the jsonnet layer.
+
+Each entry is either:
+
+1. A symbol, which is interpreted as a package to be installed, or
+
+2. A list of the form (PACKAGE KEYS...), where PACKAGE is the
+    name of the package to be installed or loaded, and KEYS are
+    any number of keyword-value-pairs.
+
+    The following keys are accepted:
+
+    - :excluded (t or nil): Prevent the package from being loaded
+      if value is non-nil
+
+    - :location: Specify a custom installation location.
+      The following values are legal:
+
+      - The symbol `elpa' (default) means PACKAGE will be
+        installed using the Emacs package manager.
+
+      - The symbol `local' directs Spacemacs to load the file at
+        `./local/PACKAGE/PACKAGE.el'
+
+      - A list beginning with the symbol `recipe' is a melpa
+        recipe.  See: https://github.com/milkypostman/melpa#recipe-format")
