+Development
+===========
+
+All the boiler plate needed to show screens has been written. To develop your
+own custom screens, however, you will need to know some SDL2. There is no real
+drawing api, to allow you to have as much control over the display as possible.
+
+dashboard uses a few objects for displaying things to the screen however, to
+interact with the memory management. 
+
+First off, the default configuration is similar to web development "Carousels".
+A series of **panels** are shown to the user by cycling through one by one.
+
+A **board** is a singleton, and represents the physical display board. 
+There is only one per instance of the program, and its has several **panels**
+
+A **panel** is an object representing a slide on screen. This is a page with
+weather, a news feed, etc. It is one of the scrolling pages shown to the user.
+This is what you will need to write.
+
+Each **panel** has a `draw()` function that you must implement. This will draw
+everything to the screen using SDL2's API. If you want functions for getting
+data, several threads, etc, **it is the panel's responsibility to implement
+this**. The **board** provides a memory API, however you do not have to use
+it.
+
+The provided memory api stores textures (SDL_Texture), fonts (TTF_Font), and
+strings (SDL_Texture). Both static values can be added that will exist for the
+lifetime of the program, as well as dynamic versions that will be stored in a
+cache (As of writing, only dynamically cached strings are implemented). All
+functions related to looking up memory stored in these containers is performed
+in O(1) time.
+
+The SDL_Window and SDL_Renderer are provided as static globals, accessible via
+the **board** object. 
+
+Each **panel** is also recommended to add its own config.hpp file for
+configuring possible settings. All static files that it needs should be placed
+in the main config.hpp file
+
+Things you need to implement as a panel creator
+-----------------------------------------------
+
+- `void mypanel::draw()`
+- `mypanel::mypanel()`
+- `mypanel::~mypanel()`
+- `size_t mypanel::_time_on_screen` 
+- `const_resources`
+
+And be sure to inheret from dashboard::panel !
