 Most of the space is dedicated
 to setting up the clocks, GPIO, and UART.
 
-Current status: almost complete.
-Right now it simply echos characters received over UART.
+Enter a series of octal halfwords
+then press G to jump to the beginning of SRAM
+and begin executing them as instructions.
+
+This is the first step in bootstrapping the whole system.

+%% Better editor

+%% A more robust and user-friendly hex-editor.
+%% It can duplicate itself.
 
 ## Assembler
 
-An assembler that can assemble itself (WIP)
+This is a single-pass assembler
+supporting most of the ARMv6-M instruction set
+using a simplified instruction syntax
+in which there are
+no labels,
+only octal literals,
+and unambiguous instruction mnemonics.
+
+It does not allow the user to type invalid instructions.

+## Better Assembler
 
 Goals:
 - A subset of GNU `as` syntax
 - Reasonably extensible
 - Small code size

+
+%% A LISP interpreter for the Raspberry Pi Pico,
