+## Hostnames
+
+Nyx seperates hostnames as distinct namespaces with their own content.
+
+At the moment you cannot port content between namespaces.
+
+## Administration
+
+The administration panel is available under `/admin/` (don't forget the trailing slash), the default login is `admin` with password `admin`. It is recommended to add a new administrator and delete the default ID.
+
+Here you can add boards, set board rules and start a database cleanup.
+
+The cleanup will remove entries older than 7 days, deleted and orphaned threads and replies.
+
+Once logged in as administrator you can also delete posts on the setup boards
+or mark your own posts as special (though still anonymous)
+
+## Posting
+
+Posts are limited to 10k characters and uploads to 10MB including Base64 overhead (realistically you should be able to upload a 7MB file)
+
+Nyx includes a system called "Trollthrottle". It will rate content based on how well it compresses, it's length and number of lines and the occurence of (currently fixed) keywords.
+
+The end result is a spam score and a captcha probability, both displayed along
+each post. The captcha probability specifies how like it is that a user
+will fail a captcha despite having entered it correctly. This is capped at 99%, which means only 1 out of 100 correct solutions will be accepted.
+
+This systems does not stop all trolls but will make it harder for people to post spam by forcing them to do more work.
+
+## TripCodes
+
+Tripcodes are non-traditional, they are calculated as the first 8 bytes of the
+Blake2b Hashsum of the entered Code in Base64 Encoding.
+
+Tripcodes do not offer a guarantee that a user is who they say they are as the
+codes can be trivially cracked even on a mobile device.

 ## Configuration
 
 The configuration file is written in YAML.
 
-The following is a list of options available;
+The following is a list of options available (and supported);
 
-* `disable_security` - Disabled some HTTPS only options for cookies or redirects
 * `secret` - Secret used for User Login, CSRF and Session Management, default is `changeme`
 * `listen_on` - Defaults to `:8080`, specifies on which port the HTTP server is launched. Nyx will not utilize this value otherwise so proxying is safe.
 * `hosts` - A whitelists of hostnames that are allowed to be used. Nyx uses hostnames to differentiate several board collections.
 * `db.file` - File to use for data storage, defaults to `:memory:` which means in-memory storage
 * `site.title` - Site Title
-* `site.description` - Site Description

+* `site.description` - Site Description
+* `captcha` - Captcha Mode, currently only `internal` is supported
