I am going to let it sit for a week before looking at it again. Then I will rework as needed and submitte for review. In the mean time I am starting on a introduction chapter. This will be a very high level overview. Below is a first stab at the outline. 1.1. Linux ................................................ 1.1.1. Linux Overview ................... 1.1.2. Linux Arctoture ................... 1.1.3. Linux Development Model.. 1.1.4. Linux Open Source.............. 1.2. Embedded Device ............................ 1.2.1. Device Architure.................. 1.2.2. Processor.............................. 1.2.3. Storage................................. 1.2.4. Device.................................. 1.3. Linux Distribution............................ 1.3.1. Kernel .................................. 1.3.2. Userspace............................. 1.3.3. File System .......................... 1.3.4. Updating .............................. 1.4. System startup .................................. ... 1.5. Host/Target ....................................... ... 1.6. Overview .......................................... 1.7. History.............................................. > For starters a diagram would do some good.

At this point, what would be most helpful is looking at and tearing apart the suggestions and drafts I submit;) Between the introduction and the getting started we should be able to provide a good big picture. Additionally, we can define terms which can be used consistently through the rest of the documentation. > David, will you also write on how to set up an OEDEV directory sturcure/ > sharing of working directories etc?

I think we will have a better idea of the full outline after the introduction chapter is more filled in. Thanks David Farning
