Implemented --debug, updated README

Closes #8, Closes #7

README.md

@@ -23,3 +23,59 @@ Now you can use `datasette publish now` to publish your data:
     datasette publish now2 my-database.db --project=my-database
 
 The `--project` argument is required - it specifies the project name that should be used for your deployment. This will be used as part of the deployment's URL.
+
+### Other options
+
+* `--no-prod` deploys to the project without updating the "production" URL alias to point to that new deployment. Without that option all deploys go directly to production.
+* `--debug` enables the Now CLI debug output
+* `--token` allows you to pass a Now authentication token, rather than needing to first run `now login' to configure the tool
+
+### Full help
+
+**Warning:** Some of these options are not yet implemented in the alpha version of this plugin. In particular, the following do not yet work:
+
+* `--extra-options`
+* `--static`
+* `--plugin-secret`
+* `--version_note`
