+
+### How to use this image
+
+The following 1 liner will get you up and running with a default configuration.
+
+Start a `venatorfox/simplesamlphp` instance, expose port 80.
+
+```console
+$ docker run --name some-simplesamlphp -p80:80 venatorfox/simplesamlphp:latest
+```
+Visit the site at http://localhost, default unconfigured username is "admin" and password is "123".
+
+Of course, running with the default configuration and no volumes is not what is desired.  
+The next sections below will show available runtime environment variables for a more specific configuration.
+
+> The config.php will be created at run and baked into the SimpleSAMLphp Core Install.
+> This will allow easy future upgrades, as you can simply destroy the container and bring it up with a new version.
+> The docker environment variables configured at runtime will be applied to the default config, pulled from SimpleSAMLphp.
+
+> The purpose of this image is to store as much ephemeral data inside the container as possible for easy upgrades.
+> This is controlled by how you mount docker volumes. Examples are presented below.
+
+### More Complex Examples
+Some more complex (ie. with SSL termination, memcache, null client, etc...) setup examples are located in the README.md within the [examples directory](https://github.com/Venator-Fox/docker-simplesamlphp/tree/master/examples).
+
+### Supported Volume Mount Options for Pre-Seeding
+
+The following directories will pre-seed if they are mounted.  
+Subdirectores will not seed, so data must already exist if volume mounting a subdirectory.
+
+If the directory is not mounted, it will use its ephemeral counterpart in the container which is ideal, explained below.
+Note that once a directory is mounted, it will need to be upgraded manually for future SimpleSAMLphp releases if applicable.
+If a mounted directory disappears from the host, it will pre-seed again with defaults from the SimpleSAMLphp install on restart.
+If reverting to a default directory is desired, remove the host directory and adjust the docker run command to exclude the mount.
+
+Some directories will probably never need manually updated as SimpleSAMLphp will not update them in new versions.
+`/cert` and `/metadata` are examples of directories that should always be volume mounted, as it contains data that must persist, is very organization specific, and will probably never or rarely be changed by SimpleSAMLphp releases.
+
+Something like `/bin` should never be volume mounted unless it's for development purposes, as it will likley be upgraded by SimpleSAMLphp in new versions.
+
+Be sure to check new SimpleSAMLphp releases to see if manual upgrades need done to a directory that was mounted.
+Check [SimpleSAMLphp docs](https://simplesamlphp.org/docs/stable/simplesamlphp-install) installation section 5 for specifics.
+
+Individual files can also be mounted, but will not pre-seed content. It must pre-exist before starting the container.
+Mounting the `authsources.php` file is a good example, as `/config` will probably not be mounted.
+Another example, if using composer, the `composer.json` and `composer.lock` files will need mounted.
+
+This will vary greatly depending on use. A compose file similar to a production instance as is at the end of this README.
+
+| Directory | Opinion |
+| ------ | ------ |
+| /var/simplesamlphp/attributemap | Mount if additional mappings are needed. |
+| /var/simplesamlphp/bin | Probably should not be volume mounted. |
+| /var/simplesamlphp/cache | -- |
+| /var/simplesamlphp/cert | Should always be volume mounted. |
+| /var/simplesamlphp/config | Should probably not be volume mounted as it is configured via runtime environment variables. This should stay ephemeral. |
+| /var/simplesamlphp/config-templates | -- |
+| /var/simplesamlphp/data | -- |
+| /var/simplesamlphp/dictionaries | Depreciated as of 1.15.0. Use locales instead. |
+| /var/simplesamlphp/docs | -- |
+| /var/simplesamlphp/extra | -- |
+| /var/simplesamlphp/lib | -- |
+| /var/simplesamlphp/locales | Mount for customized user messages and translations. |
+| /var/simplesamlphp/log | If using docker log redirection, this cannot be volume mounted. If docker logs write to a file, this should be volume mounted so logs do not grow inside the container. |
+| /var/simplesamlphp/metadata | Should always be volume mounted, very specific to organization. |
+| /var/simplesamlphp/metadata-templates | -- |
+| /var/simplesamlphp/modules | Can be volume mounted for easier module customization |
+| /var/simplesamlphp/schemas | -- |
+| /var/simplesamlphp/src | -- |
+| /var/simplesamlphp/templates | -- |
+| /var/simplesamlphp/tests | -- |
+| /var/simplesamlphp/vendor | -- |
+| /var/simplesamlphp/www | Can be volume mounted for easier www customization |
+
+### Runtime Environment Variables
+
+The following variables can be overridden at run or in docker-compose. 
+It is recommended to set them properly and not use default values. 
+(Unless you want an authentication service with no SSL, with your admin password being 123 (Can you not, kthx)).
+
+| Variable | Default Value | Description |
+| ------ | ------ | ------ |
+| CONFIG_BASEURLPATH | simplesaml/ | If using SSL behind a proxy enter the base URL here, otherwise IdP metadata will use http://. Format is [(https)://(hostname)[:port]]/[path/to/simplesaml/]. |
+| CONFIG_AUTHADMINPASSWORD | SSHA256 hash of '123' | Plain text works as well. Use PWGen to generate a hash for this variable. Refer to [SimpleSAMLphp docs](https://simplesamlphp.org/docs/stable/simplesamlphp-install), installation guide section 7. |
+| CONFIG_SECRETSALT | defaultsecretsalt | Refer to [SimpleSAMLphp docs](https://simplesamlphp.org/docs/stable/simplesamlphp-install), installation guide section 7 if help is needed for generating one. |
+| CONFIG_TECHNICALCONTACT_NAME | Administrator | Name of the Admin of Rainy Clouds, 42nd of Their Name, Breaker of Sanity, and ~~Destroyer~~ Protector of the Federation |
+| CONFIG_TECHNICALCONTACT_EMAIL | na@example.org | Address of hate mail and applicaton exception logs to send to. |
+| CONFIG_LANGUAGEDEFAULT | en | -- |
+| CONFIG_TIMEZONE | America/Chicago | Visit the [php.net man pages](http://php.net/manual/en/timezones.america.php) for the options, the one linked is for 'Murica. |
+| CONFIG_TEMPDIR | /tmp/simplesaml | -- |
+| CONFIG_SHOWERRORS | true | Shows detailed errors to the user if one occurs. |
+| CONFIG_ERRORREPORTING | true | Allow users to send reports from SimpleSAMLphp to the technicalcontact. |
+| CONFIG_ADMINPROTECTINDEXPAGE | false | Require admin password to access frontpage_federation index. |
+| CONFIG_ADMINPROTECTMETADATA | false | Require admin password to access public IdP metadata. |
+| CONFIG_DEBUG | false | Enable debugging to logs, requires CONFIG_LOGGINGLEVEL be set to DEBUG. |
+| CONFIG_LOGGINGLEVEL | NOTICE | Options are ERR, WARNING, NOTICE, INFO, DEBUG |
+| CONFIG_LOGGINGHANDLER | file | Default different from official default of syslog due to systemd not running in containers. |
+| CONFIG_LOGFILE | simplesamlphp.log | -- |
+| CONFIG_ENABLESAML20IDP | false | Enable SAML20 IdP |
+| CONFIG_ENABLESHIB13IDP | false | Enable Shibboleth13 IdP |
+| CONFIG_SESSIONDURATION | 8 * (60 * 60) | -- |
+| CONFIG_SESSIONDATASTORETIMEOUT | (4 * 60 * 60) | -- |
+| CONFIG_SESSIONSTATETIMEOUT | (60 * 60) | -- |
+| CONFIG_SESSIONCOOKIELIFETIME | 0 | -- |
+| CONFIG_SESSIONPHPSESSIONCOOKIENAME | SimpleSAML | -- |
+| CONFIG_SESSIONPHPSESSIONSAVEPATH | null | This must be set to a valid path if using phpsession, otherwise a redirect loop on login will occur. `/var/lib/php/session/` will be inserted if phpsession is used while this value is still unconfigured. |
+| CONFIG_SESSIONPHPSESSIONHTTPONLY | true | -- |
+| CONFIG_SESSIONREMEMBERMEENABLE | false | -- |
+| CONFIG_SESSIONREMEMBERMECHECKED | false | -- |
+| CONFIG_SESSIONREMEMBERMELIFETIME | (14 * 86400) | -- |
+| CONFIG_SESSIONCOOKIESECURE | false | -- |
+| CONFIG_ENABLEHTTPPOST | false | -- |
+| CONFIG_THEMEUSE | default | -- |
+| CONFIG_STORETYPE | phpsession | If using `memcache` option, CONFIG_MEMCACHESTORESERVERS and CONFIG_MEMCACHESTOREPREFIX will need to be set. |
+| CONFIG_MEMCACHESTORESERVERS | See Format Below* | Was unable to make this an easy variable, the format of the array is given below in a 2x2 example. Keep the format but replace the hostnames. |
+| CONFIG_MEMCACHESTOREPREFIX | null | `simplesamlphp` can be used in most cases. |
+| WWW_INDEX | core/frontpage_welcome.php | Page to direct to if a user accesses the IdP/SP directly. Can be set to an authentication test for example. |
+| OPENLDAP_TLS_REQCERT | demand | As per ldap man pages, Options are `never` `allow` `try` `demand`. If using Active Directory or OpenLDAP with TLS, logins will be rejected if the directory certificate is self-signed with the default `demand` value. This can be set to `never` for testing purposes. Refer to ldap.conf man page section 5 for more details. |
+| MTA_NULLCLIENT | false | Set to true to configure null client for sending e-mails.  Visit the [Postfix Standard Configuration Examples](http://www.postfix.org/STANDARD_CONFIGURATION_README.html) for explaination of a null client. If this is set to false, postfix will be purged from the container. |
+| POSTFIX_MYHOSTNAME| host.domain.tld | Set to the FQDN of your host. ie `auth.example.com`. |
+| POSTFIX_MYORIGIN | $myhostname | Set to `$mydomain` as per postfix docs for null client. |
+| POSTFIX_RELAYHOST | $mydomain | Set to `$mydomain` again as per postfix docs for null client. |
+| POSTFIX_INETINTERFACES | localhost | Set to loopback-only as per postfix docs for null client. |
+| POSTFIX_MYDESTINATION | | Leave as empty string as per postfix docs for null client. |
+| DOCKER_REDIRECTLOGS | false | Redirect logs written to the log file by SimpleSAMLphp to `/dev/console`. Please run with -t as a TTY will need allocated for this to work. |
+
+Default CONFIG_MEMCACHESTORESERVERS format, 2 pair of 2 example. Use this template and replace the hostnames. Check compose file for usage example:
+```console
+    'memcache_store.servers' => array(\n        array(\n             array('hostname' => 'mc_a1'),\n             array('hostname' => 'mc_a2'),\n        ),\n        array(\n             array('hostname' => 'mc_b1'),\n             array('hostname' => 'mc_b2'),\n        ),
+```
+
+> For the POSTFIX_ environment variables, the $ character will need to be escaped with another $. ie. enter `$$mydomain`.
+
+### Maintenance
+
+This is being actively maintained and is running in production for several organizations.
+Please [create an issue](https://github.com/Venator-Fox/docker-simplesamlphp/issues) if needed or if additional variables/features are desired.
