+
+# Preqreuisites
+
+You will need to know the basics of Git. Git is the system used to track
+changes and update Upsilon. you will need to know the wwhat a git repository is,
+how to pull changes from a repository, what commit hashes are and how to make
+branches.
+
+You must know basic Linux shell (change directories, edit files with `vi`)
+and basic SSH usage (sftp, ssh).
+
+Knowledge of Micropython (a subset of Python) is required for scripting.
+
+
+# Building and Booting
+
+Follow `docs/docker.md` to setup the build environment, build Upsilon, and
+boot Upsilon.

 * Always initialize registers.
 * Rerun tests after every change to the module.
 
+## Conventions
+
+### Wires
+
+* When specfying widths, include the total bit width and subtract 1 from it,
+  even in cases where the bit width is constant. For example, to declare an
+  8-bit register, write `reg [8-1:0] r1`.
+* If a wire is active low, append `_L` to the end of the name.
+
+### Parameters
+
+* Parameters are always in all caps.
+* Parameters ending in `_WID` are bit widths that do not have an associated
+  number (eg DAC widths, input register sizes).
+* Parameters ending in `_SIZ` are the amount of bits required to store a
+  certain number. These parameters can be calculated using `floor(log2(number) + 1)`.
+  For example,
+    * `255` has a `SIZ` of 8 (8 bits are required to store 255).
+    * `256` has a `SIZ` of 9
+    * `254`, `253`, etc. have a `SIZ` of 8
+    * `127` has a `SIZ` of 7
