+
+Fission Specs
+=============
+
+This is a set of specifications for a Fission app.  This includes functions,
+environments, and triggers; we collectively call these things "resources".
+
+How to use these specs
+----------------------
+
+These specs are handled with the 'fission spec' command.  See 'fission spec --help'.
+
+'fission spec apply' will "apply" all resources specified in this directory to your
+cluster.  That means it checks what resources exist on your cluster, what resources are
+specified in the specs directory, and reconciles the difference by creating, updating or
+deleting resources on the cluster.
+
+'fission spec apply' will also package up your source code (or compiled binaries) and
+upload the archives to the cluster if needed.  It uses 'ArchiveUploadSpec' resources in
+this directory to figure out which files to archive.
+
+You can use 'fission spec apply --watch' to watch for file changes and continuously keep
+the cluster updated.
+
+You can add YAMLs to this directory by writing them manually, but it's easier to generate
+them.  Use 'fission function create --spec' to generate a function spec,
+'fission environment create --spec' to generate an environment spec, and so on.
+
+You can edit any of the files in this directory, except 'fission-deployment-config.yaml',
+which contains a UID that you should never change.  To apply your changes simply use
+'fission spec apply'.
+
+fission-deployment-config.yaml
+------------------------------
+
+fission-deployment-config.yaml contains a UID.  This UID is what fission uses to correlate
+resources on the cluster to resources in this directory.
+
+All resources created by 'fission spec apply' are annotated with this UID.  Resources on
+the cluster that are _not_ annotated with this UID are never modified or deleted by
+fission.
