+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Lemur can import and export certificate data to and from a Hashicorp Vault secrets store. Lemur can connect to a different Vault service per source/destination.
+
+.. note:: This plugin does not supersede or overlap the 3rd party Vault Issuer plugin.
+
+.. note:: Vault does not have any configuration properties however it does read from a file on disk for a vault access token. The Lemur service account needs read access to this file.
+
+Vault Source
+""""""""""""
+
+The Vault Source Plugin will read from one Vault object location per source defined. There is expected to be one or more certificates defined in each object in Vault.
+
+Vault Destination
+"""""""""""""""""
+
+A Vault destination can be one object in Vault or a directory where all certificates will be stored as their own object by CN.
+
+Vault Destination supports a regex filter to prevent certificates with SAN that do not match the regex filter from being deployed. This is an optional feature per destination defined.

+
+Add support for LetsEncrypt
+===========================
+
+LetsEncrypt is a free, limited-feature certificate authority that offers publicly trusted certificates that are valid
+for 90 days. LetsEncrypt does not use organizational validation (OV), and instead relies on domain validation (DV).
+LetsEncrypt requires that we prove ownership of a domain before we're able to issue a certificate for that domain, each
+time we want a certificate.
+
+The most common methods to prove ownership are HTTP validation and DNS validation. Lemur supports DNS validation
+through the creation of DNS TXT records.
+
+In a nutshell, when we send a certificate request to LetsEncrypt, they generate a random token and ask us to put that
+token in a DNS text record to prove ownership of a domain. If a certificate request has multiple domains, we must
+prove ownership of all of these domains through this method. The token is typically written to a TXT record at
+-acme_challenge.domain.com. Once we create the appropriate TXT record(s), Lemur will try to validate propagation
+before requesting that LetsEncrypt finalize the certificate request and send us the certificate.
+
+.. figure:: letsencrypt_flow.png
+
+To start issuing certificates through LetsEncrypt, you must enable Celery support within Lemur first. After doing so,
+you need to create a LetsEncrypt authority. To do this, visit
+Authorities -> Create. Set the applicable attributes and click "More Options".
+
+.. figure:: letsencrypt_authority_1.png
+
+You will need to set "Certificate" to LetsEncrypt's active chain of trust for the authority you want to use. To find
+the active chain of trust at the time of writing, please visit `LetsEncrypt
+<https://letsencrypt.org/certificates/>`_.
+
+Under Acme_url, enter in the appropriate endpoint URL. Lemur supports LetsEncrypt's V2 API, and we recommend you to use
+this. At the time of writing, the staging and production URLs for LetsEncrypt V2 are
+https://acme-staging-v02.api.letsencrypt.org/directory and https://acme-v02.api.letsencrypt.org/directory.
+
+.. figure:: letsencrypt_authority_2.png
+
+After creating the authorities, we will need to create a DNS provider. Visit `Admin` -> `DNS Providers` and click
+`Create`. Lemur comes with a few provider plugins built in, with different options. Create a DNS provider with the
+appropriate choices.
+
+.. figure:: create_dns_provider.png
+
+By default, users will need to select the DNS provider that is authoritative over their domain in order for the
+LetsEncrypt flow to function. However, Lemur will attempt to automatically determine the appropriate provider if
+possible. To enable this functionality, periodically (or through Cron/Celery) run `lemur dns_providers get_all_zones`.
+This command will traverse all DNS providers, determine which zones they control, and upload this list of zones to
+Lemur's database (in the dns_providers table). Alternatively, you can manually input this data.
