+Deployment Secrets
+==================
+
+Deploying PrivateStorageio requires certain secrets.
+For the localdev grid these secrets are kept in this (public) directory.
+This is intended to help make it as easy as possible to launch a local deployment.
+It also serves as an example of what secrets are required for any other deployment.
+
+You can find more information about some of these secrets in ``ops/generating-keys.rst``.
+
+deploy_key
+----------
+
+This SSH private key authenticates an account used by the continuous deployment system.
+Each node authorizes that account to trigger a deployment update on itself. 
+The corresponding SSH public key is kept in the ``public-keys`` location.
+
+grafana-admin.password
+----------------------
+
+This is the initial admin password for the Grafana web admin on the monitoring host.
+
+grafana-slack-url
+-----------------
+
+This file is read by Grafana's systemd service to set an environment variable with a secret Slack WebHook URL to post alerts to.
+The only line in the file should be the secret URL.
+Use the url from `this 1Password entry <https://privatestorage.1password.com/vaults/7flqasy5hhhmlbtp5qozd3j4ga/allitems/cgznskz2oix2tyx5xyntwaos5i>`_ or get a new secret URL for your Slack channel at https://www.slack.com/apps/A0F7XDUAZ.
+
+grafana-zulip-url
+-----------------
+
+This file should contain a single line with the secret Zulip alerting Webhook Bot URL.
+The URLs for Staging and Production are both stored in 1Password.
+See `https://zulip.com/integrations/doc/grafana`_ for documentation and ``grid/local/private-keys/grafana-zulip-url`` for an example.
+
+stripe.secret
+-------------
+
+This is the Stripe secret key which the payment server uses to finalize payment processing using Stripe.
+The corresponding Stripe public key is kept in the ``public-keys`` location.
+
+ristretto.signing-key
+---------------------
+
+This is the Ristretto-group private key used by the ZKAP issuer.
+
+monitoringvpn
+-------------
+
+This directory holds Wireguard private keys for each of the hosts so they can participate in the deployment VPN.
+The corresponding public keys are kept in the ``public-keys`` location.
+
+payments-localdev-ssl
+---------------------
+
+This secret is *only* present for the localdev grid.
+This contains a TLS certificate and private key for the payment server.
+Other deployments will automatically generate a key and obtain a certificate from Let's Encrypt.
