README-new.md

   1 **IMPORTANT**: This file is in active development along with the policies in Firefox. To get the policy information that corresponds to a specific release, go to https://github.com/mozilla/policy-templates/releases.
   2
   3 Policies can be specified using the Group Policy templates on Windows (https://github.com/mozilla/policy-templates/tree/master/windows), configuration profiles on macOS (https://github.com/mozilla/policy-templates/tree/master/mac), or by creating a file called `policies.json`. On Windows, create a directory called `distribution` where the EXE is located and place the file there. On Mac, the file goes into `Firefox.app/Contents/Resources/distribution`.  On Linux, the file goes into `firefox/distribution`, where `firefox` is the installation directory for firefox, which varies by distribution.
   4
   5 The content of the JSON file should look like this:
   6 ```
   7 {
   8   "policies": {
   9     ...POLICIES...
  10   }
  11 }
  12 ```
  13 Policies are documented below.
