+
+On initialization of the kernel, a GlobalInformationTable is setup. This contains the address of the first DataLookupEntry
+
+# The Memory Manager
+
+The manager will init itself if there are no blocks. The manager is modeled after a double LinkedList and is not a List.
+
+# Memory Layout
+The layout does  not have a preset list or table but rather every item has meta data linking the next and previous item. This allows for a robust system.
+
+The data layout is as follows:
+
+````
+Block|Block|Block etc.
+
+Block =
+
+Meta Data|Data
+
+Meta data =
+4 bytes (preveus block address start)|4 bytes (next block address start)|4 bytes (curent[this] block size)| 4 bytes (curent[this] block flag)
+```
+BlockFlags :
+
+```
+Allocated = 0,
+Free = 1,
+```
+
+the final layout looks like this:
+
+```
+4 bytes|4 bytes|4 bytes|4 bytes | (size of Block) bytes  |  4 bytes|4 bytes|4 bytes | 4 bytes | (size of Block) bytes  | etc
+
+```
+Note:
+this means the smallest size an Block can occupy is 17 bytes, 16 bytes for the header and 1 for the smallest data type a byte.
+
+# Usage
+
+### Allocation
+  Allocating a block happens by finding the first free block and split it (if necessary).
+
+## Deallocation
+  Freeing a block is easy set its flag (in the metadata) to free.
