+How to theme Red - by Olivier Migeot
+====================================
+
+This is a short documentation on what I found while trying to modify Red's appearance.
+
+First, you'll need to create a new theme. This is in /view/theme, and I chose to copy 'redbasic' since it's the only available for now. Let's assume I named it <theme>.
+
+Oh, and don't forget to rename the _init function in <theme>/php/theme.php to be <theme>_init() instead of redbasic_init().
+
+At that point, if you need to add javascript or css files, add them to <theme>/js or <theme>/css, and then "register" them in <theme>_init() through head_add_js('file.js') and head_add_css('file.css').
+
+Now you'll probably want to alter a template. These can be found in in /view/tpl OR view/<theme>/tpl. All you should have to do is copy whatever you want to tweak from the first place to your theme's own tpl directory.

+The Red Matrix
+==============   
+
+***"Connected Websites"***
+
+The modern web is "missing" a few important pieces which would make it much more useful. Many corporations have stepped in with products to supply these missing pieces, but with a loss of freedom and privacy and increased **centralisation**. 
+
+Centralisation is generally considered a bad thing in network design as the loss of one critical node or centralised service could seriously impact the entire network - possibly taking a long time to recover. Recognising this, the original web was based on decentralised services. Over the years, this fundamental design strength has been largely overlooked, as people congregate into centralised services which provide the missing pieces. 
+
+These missing pieces are (in no particular order):
+
+- Secure and private "spam free" communications
+
+- Identity and "single-signon" across the entire network
+
+- Privacy controls and permissions which extend to the entire network
+
+- Directory services (like a phone book)
+
+
+
+The Red Matrix (sometimes referred to as just "Red") is a collection of web servers and services which provides these missing pieces, but within a decentralised identity and messaging framework (known as "Zot"). Red operates as an independent network within the larger internet where all the nodes or servers (we call them "hubs") are able to fully interact with each other in ways that are simply not possible using other services. Additionally the owners of each network hub have the ability to set their own rules with regard to communications privacy and data ownership, because each operates with complete independence. These hubs require only slightly more resources than a blog or content management system, and the software is being designed with the ability to natively incorporate both kinds of functionality, as well as cloud storage. 
+
+![The Red Matrix model](images/red_antiprism.png)
+
+
+Whilst other decentralised communications networks exist, an additional weakness we've found in the implementation of these systems is the binding of network identity with the physical server where it resides; for example if you are "eric@example.website", your identity is often tied permanently to "example.website". We see this as a problem. Many hubs on the Indie Web are run by enthusiasts with varying skill levels and financial resources - and the technology is changing quite rapidly. Often the cost or workload involved in maintaining these services becomes a burden (or hardware fails) and people or entire social communities are left stranded when their server goes offline. Their identity no longer exists. They may have to "start over" building their social circle from scratch when this happens. In some cases communities are unable to recover from this kind of disruption and the entire community dissolves. 
+
+We've been working on decentralisation for several years and have seen this happen time and time again. 
+Within the Red Matrix, identity is nomadic. It defines you and it belongs to you - and is not locked to a particular network address. You can take your identity, and all your friends and associates with you - to any other hub in the network, at any time. If your hub goes offline for any reason, you have the ability to relocate to any other hub and carry on as if nothing happened. You still have all your friends and associations.
+
+ 
+The Red Matrix is free and open source distributed under the MIT license.
+
+
+Currently the project is in "Developer Preview". A lot of work remains, but many important bits are functioning. Please connect with one of the developer channels ("Channel One" would be a good choice) if you are interested in helping us out.

+Red Twitter API
+===============
+
+The "basic" Red web API is based on the Twitter API, as this provides instant compatibility with a huge number of third-party clients and applications without requiring any code changes on their part. It is also a super-set of the StatusNet version of the Twitter API, as this also has existing wide support.
+
+Red has a lot more capability that isn't exposed in the Twitter interfaces or where we are forced to "dumb-down" the API functions to work with the primitive Twitter/StatusNet communications and privacy model. So we plan to extend the Twitter API in ways that will allow Red-specific clients to make full use of Red features without being crippled. 
+
+A dedicated Red API is also being developed to work with native data structures and permissions and which do not require translating to different privacy and permission models and storage formats. This will be described in other documents. The prefix for all of the native endpoints is 'api/red'. 
+
+Red provides multiple channels accesible via the same login account. With Red, any API function which requires authentication will accept a parameter &channel={channel_nickname} - and will select that channel and make it current before executing the API command. By default, the default channel associated with an account is selected. 
+ 
+Red also provides an extended permission model. In the absence of any Red specific API calls to set permissions, they will be set to the default permissions settings which are associated with the current channel.  
+
+Red will probably never be able to support the Twitter 'api/friendships' functions fully because Red is not a social network and has no concept of "friendships" - it only recognises permissions to do stuff (or not do stuff as the case may be).

+Red development - some useful basic functions
+=============================================
+
+
+
+* get_account_id()
+
+Returns numeric account_id if authenticated or 0. It is possible to be authenticated and not connected to a channel.
+
+* local_user()
+
+Returns authenticated numeric channel_id if authenticated and connected to a channel or 0. Sometimes referred to as $uid in the code.
+
+* remote_user()
+
+Returns authenticated string hash of Red global identifier, if authenticated via remote auth, or an empty string.
+
+* get_app()
+
+Returns the global app structure ($a).
+
+* App::get_observer()
+
+(App:: is usually assigned to the global $a), so $a->get_observer() or get_app()->get_observer() - returns an xchan structure representing the current viewer if authenticated (locally or remotely).
+
+* get_config($family,$key), get_pconfig($uid,$family,$key)
+
+Returns the config setting for $family and $key or false if unset. 
+
+* set_config($family,$key,$value), set_pconfig($uid,$family,$key,$value)
+
+Sets the value of config setting for $family and $key to $value. Returns $value. The config versions operate on system-wide settings. The pconfig versions get/set the values for a specific integer uid (channel_id).  
+
+* dbesc()
+
+Always escape strings being used in DB queries. This function returns the escaped string. Integer DB parameters should all be proven integers by wrapping with intval()
+
+* q($sql,$var1...)
+
+Perform a DB query with the SQL statement $sql. printf style arguments %s and %d are replaced with variable arguments, which should each be appropriately dbesc() or intval(). SELECT queries return an array of results or false if SQL or DB error. Other queries return true if the command was successful or false if it wasn't. 
+
+* t($string)
+
+Returns the translated variant of $string for the current language or $string (default 'en' language) if the language is unrecognised or a translated version of the string does not exist.
+
+* x($var), $x($array,$key)
+
+Shorthand test to see if variable $var is set and is not empty. Tests vary by type. Returns false if $var or $key is not set.
+If variable is set, returns 1 if has 'non-zero' value, otherwise returns 0. -- e.g. x('') or x(0) returns 0;
+
+
+
