 # Kibana Reporting
 
-An awesome Kibana reporting plugin
-
-# Development
-
-Assuming you've checked out x-plugins next to kibana...
-
-- Run `yarn kbn bootstrap`
-- Run `yarn start` to watch for and sync files on change
-- Open a new terminal to run Kibana - use `yarn start` to launch it in dev mode
-  - Kibana will automatically restart as files are synced
-  - If you need debugging output, run `DEBUG=reporting yarn start` instead
-
-If you have installed this somewhere other than via x-plugins, and next to the kibana repo, you'll need to change the `pathToKibana` setting in `gulpfile.js`
-
-# Conventions
-
-This plugins adopts some conventions in addition to or in place of conventions in Kibana (at the time of the plugin's creation):
-
-## Folder structure
-```
-export_types/ (contains public and server aspects of the different export types) 
-  printable_pdf/ 
-    public/
-    server/
-  csv/
-    public/
-    server/
-public/ (shared public code for all export types)
-server/ (shared server code for all export types)
-```
-
-This folder structure treats the different export_types like Plugins, with their public/server code being separate in a folder.
