 ## Usage
 
-### Prerequisites 
-* You will need a github token for your account, which you can get at <https://github.com/settings/tokens>. The token needs, at a minimum, full repo scope, to be able to enumerate the user's repositories and install/remove webhooks. Therefore, in the token creation page, make sure `repo` (and its childs) are checked under `Select scopes`. The token can go in one of these two places:
-    * in a file called `github.token` in `~/.ghplugin` (or in the directory pointed by the `SecretsDir` init parameter)
-    * in an environment variable called GITHUB_PLUGIN_TOKEN
-* The machine where the plugin is running needs a public address and an open firewall that allows either port 80 (for HTTP) or port 443 (for https)

 If you want to use https (**highly recommended**), name your key and certificate `server.key` and `server.crt` and put them in `~/.ghplugin` (or in the directory pointed by the `SecretsDir` init parameter). The plugin will pick them up, validate them and start an https server. If the key and certificate are not valid, the plugin will cause falco to exit with an error.

 ## Webhook lifecycle
+
 The plugin creates a webhook for each of the instrumented repository using the token specified as the first open argument. Each webhook is configured with a unique, automatically generated secret. This allows the plugin to reject messages that don't come from the righful github webhooks.
