added some form of html isa documentation. Just converting the markdown one, which will stand as reference documentation and spec forever.

 The register machine has a (in)finite number of registers which can store a 32 bit, unsigned integer.
 Two registers play a special role: the **accumulator**, which is register number 0 by default, and the **program counter**, which defaults as register number 10.
 
+The **accumulator** is a special register that most operations use.
+The **program counter** keeps track of which instruction we're actually executing.
+
 This interpreter reads a single text file with **one instruction per line**.
 Whitespaces are ignored. Lines starting with # are treated as comments and are ignored.

+
+          Write your program in the leftmost box you see.
+
+          Press LOAD to actually load the program. You should see the instructions you've just typed on the right now.
+
+          Press RUN to execute the whole program until it halts.
+          Press RUN SINGLE STEP to execute just one instruction.
+
+          Reset will... reset everything. No program, no input, no output.
