+This directory contains ruby source files that define the available sub-
+commands of the `leap` executable.

+For example, the command:
+
+  leap compile
+
+Lives in lib/leap_cli/commands/init.rb
+
+These files use a DSL (called GLI) for defining command suites.

+This directory contains statically rendered copies of the `provider.json` file
+used by the client to "bootstrap" configure itself for use with your service
+provider.
+
+There is a separate provider.json file for each environment, although you
+should only need 'production/provider.json' or, if you have no environments
+configured, 'default/provider.json'.
+
+To clarify, this is the public `provider.json` file used by the client, not the
+`provider.json` file that is used to configure the provider.
+
+The provider.json file must be available at `https://domain/provider.json`
+(unless this provider is included in the list of providers which are pre-
+seeded in client).
+
+This provider.json file can be served correctly in one of three ways:
+
+(1) If the property webapp.domain is not configured, then the web app will be
+    installed at https://domain/ and it will handle serving the provider.json file.
+
+(2) If one or more nodes have the 'static' service configured for the provider's
+    domain, then these 'static' nodes will correctly serve provider.json.
+
+(3) Otherwise, you must copy the provider.json file to your web
+    server and make it available at '/provider.json'. The example htaccess
+    file shows what header options should be sent by the web server
+    with the response.
+
+This directory is needed for method (3), but not for methods (1) or (2).
+
+This directory has been created by the command `leap compile provider.json`.
+Once created, it will be kept up to date everytime you compile. You may safely
+remove this directory if you don't use it.
