 - When adding, removing, or changing tools, update both termui and webui
 - Unless explicitly requested, do not add backwards compatibility shims. Just change all the relevant code.
 
+## Building
+
+You can build the sketch binary with "make". The webui directory has some
+standalone "npm run dev" capability, but the main build is "make".
+
 ## Meta
 
-The program you are working on is Sketch. The program you are running is Sketch. This can be slightly confusing: Carefully distinguish the prompt and tools you have from the codebase you are working on. Modifying the code does not change your prompt or tools.

-To start a copy of sketch, use -skaband-addr="" -addr ":8080" -unsafe -prompt "some appropriate prompt". Do not use pkill or killall to stop background sketch processes--your process is called sketch! Instead, kill the pid provided by the bash tool when you started the background process. Do not browse to :80--that is your process! Instead browse to :8080.
+To start a copy of sketch, if you don't have an ANTHROPIC_API_KEY in your env
+already, you can use:
+
+  ANTHROPIC_API_KEY=fake sketch -skaband-addr= -addr ":8080" -unsafe
+
+To browse the copy of sketch you just started, browse to localhost:8080.
