 Anyways. I started to write Redis with Rust, and several years later I have
 something that is decidedly not a Redis. It's a small piece of a Redis, which
 is not particularly valuable given the existence of a full,

 ### What is it then?
 
-Ok. If it's not an entire Redis, what is it? It's lots of things! But here's
-one of them. It's a repl you can get results from. Try some of these things:
-
-* `set x foo` followed by `get x`
-* get the current list of commands with `command list`
-* `rpush l a b c` followed by `lrange l 0 -1`
+One of my favorite things about Rust is its support for compiling to [web
+assembly][wasm]. With a bit of work and a few
+caveats<sup>[2](#wasm-caveats)</sup>, you can run Rust code in the browser. The
+repl below is Bradis running in the browser via WASM. Try out some Redis
+commands!
+
+* `set x foo` - set a value
+* `get x` - get a value
+* `command list` - get a list of commands
+* `hset h x 1` - set values in a hash
+* `rpush l a b c` - push values into a list
+* `sadd s x y z` - push values into a set
+* `zadd z 1 x 2 y 3 z` - add values to a sorted set
+* `multi` - start a transaction
+* `exec` - execute a transaction
+* `client info` - get info about the current client
