 The __last__ capture is embedded in each group, so `g.String()` will return the same thing as `g.Capture.String()` and  `g.Captures[len(g.Captures)-1].String()`.
 
+If you want to find multiple matches from a single input string you should use the `FindNextMatch` method.  For example, to implement a function similar to `regexp.FindAllString`:
+
+```go
+func regexp2FindAllString(re *regexp2.Regexp, s string) []string {
+	var matches []string
+	m, _ := re.FindStringMatch(s)
+	for m != nil {
+		matches = append(matches, m.String())
+		m, _ = re.FindNextMatch(m)
+	}
+	return matches
+}
+```
+
+`FindNextMatch` is optmized so that it re-uses the underlying string/rune slice.
+
+The internals of `regexp2` always operate on `[]rune` so `Index` and `Length` data in a `Match` always reference a position in `rune`s rather than `byte`s (even if the input was given as a string). This is a dramatic difference between `regexp` and `regexp2`.  It's advisable to use the provided `String()` methods to avoid having to work with indices.

+## Catastrophic Backtracking and Timeouts
+
+`regexp2` supports features that can lead to catastrophic backtracking.
+`Regexp.MatchTimeout` can be set to to limit the impact of such behavior; the
+match will fail with an error after approximately MatchTimeout. No timeout
+checks are done by default.
+
+Timeout checking is not free. The current timeout checking implementation starts
+a background worker that updates a clock value approximately once every 100
+milliseconds. The matching code compares this value against the precomputed
+deadline for the match. The performance impact is as follows.
+
+1.  A match with a timeout runs almost as fast as a match without a timeout.
+2.  If any live matches have a timeout, there will be a background CPU load
+    (`~0.15%` currently on a modern machine). This load will remain constant
+    regardless of the number of matches done including matches done in parallel.
+3.  If no live matches are using a timeout, the background load will remain
+    until the longest deadline (match timeout + the time when the match started)
+    is reached. E.g., if you set a timeout of one minute the load will persist
+    for approximately a minute even if the match finishes quickly.
+
+Some alternative implementations were considered and ruled out. 
+
+1.  **time.Now()** - This was the initial timeout implementation. It called `time.Now()`
+    and compared the result to the deadline approximately once every 1000 matching steps.
+    Adding a timeout to a simple match increased the cost from ~45ns to ~3000ns).
+2.  **time.AfterFunc** - This approach entails using `time.AfterFunc` to set an `expired`
+    atomic boolean value. However it increases the cost of handling a simple match 
+    with a timeout from ~45ns to ~360ns and was therefore ruled out.
+3.  **counter** - In this approach an atomic variable tracks the number of live matches
+    with timeouts. The background clock stops when the counter hits zero. The benefit
+    of this approach is that the background load will stop more quickly (after the
+    last match has finished as opposed to waiting until the deadline for the last
+    match). However this approach requires more atomic variable updates and has poorer
+    performance when multiple matches are executed concurrently. (The cost of a
+    single match jumps from ~45ns to ~65ns, and the cost of running matches on
+    all 12 available CPUs jumps from ~400ns to ~730ns).
+
+## ECMAScript compatibility mode
+In this mode the engine provides compatibility with the [regex engine](https://tc39.es/ecma262/multipage/text-processing.html#sec-regexp-regular-expression-objects) described in the ECMAScript specification.
+
+Additionally a Unicode mode is provided which allows parsing of `\u{CodePoint}` syntax that is only when both are provided.

-This program reads a file containing function prototypes
-(like syscall_aix.go) and generates system call bodies.
-The prototypes are marked by lines beginning with "//sys"
-and read like func declarations if //sys is replaced by func, but:
-	* The parameter lists must give a name for each argument.
-	  This includes return parameters.
-	* The parameter lists must give a type for each argument:
-	  the (x, y, z int) shorthand is not allowed.
-	* If the return parameter is an error number, it must be named err.
-	* If go func name needs to be different than its libc name,
-	* or the function is not in libc, name could be specified
-	* at the end, after "=" sign, like
-	  //sys	getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
-

-This program will generate three files and handle both gc and gccgo implementation:
-  - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
-  - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
-  - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
