 This functionality is targeted to assist applications/end devices that don't have proxy support, or can't run external applications (like Smart TV's). Making it possible to run Xray proxy right on network edge devices (routers) with support to route raw network traffic. \
 Primary targets are Linux based router devices. Like most popular OpenWRT option. \
-Although support for Windows is also implemented (see below).
+Support for Windows, macOS, Android and iOS is also implemented (see below).

 Note on ipv6 support. \
 Despite Windows also giving the adapter autoconfigured ipv6 address, the ipv6 is not possible until the interface has any _routable_ ipv6 address (given link-local address will not accept traffic from external addresses). \
 So everything applicable for ipv4 above also works for ipv6, you only need to give the interface some address manually, e.g. anything private like fc00::a:b:c:d/64 will do just fine
+
+## MAC OS X SUPPORT
+
+Darwin (Mac OS X) support of the same functionality is implemented through utun (userspace tunnel).
+
+Interface name in the configuration must comply to the scheme "utunN", where N is some number. \
+Most running OS'es create some amount of utun interfaces in advance for own needs. Please either check the interfaces you already have occupied by issuing following command:
+```
+ifconfig
+```
+Produced list will have all system interfaces listed, from which you will see how many "utun" ones already exists.
+It's not required to select next available number, e.g. if you have utun1-utun7 interfaces, it's not required to have "utun8" in the config. You can choose any available name, even utun20, to get surely available interface number.
+
+To attach routing to the interface, route command like following can be executed:
+```
+sudo route add -net 1.1.1.0/24 -iface utun10
+```
+```
+sudo route add -inet6 -host 2606:4700:4700::1111 -iface utun10
+sudo route add -inet6 -host 2606:4700:4700::1001 -iface utun10
+```
+Important to remember that everything written above about Linux routing concept, also apply to Mac OS X. If you simply route default route through utun interface, that will result network loop and immediate network failure.
+
+## ANDROID SUPPORT
+
+Android uses the VpnService API which provides a TUN file descriptor to the application.
+
+Obtain the fd from VpnService:
+```kotlin
+val tunFd = vpnInterface.fd
+```
+
+Set the environment variable `xray.tun.fd` (or `XRAY_TUN_FD`) to the fd number before starting Xray. This can be done from Kotlin/Java or by exposing a Go function via gomobile bindings.
+
+Build using gomobile for Android library integration:
+```
+gomobile bind -target=android
+```
+
+## iOS SUPPORT
+
+iOS uses the same utun packet format as macOS, but the file descriptor is provided by NetworkExtension.
+
+Obtain the fd from NetworkExtension:
+```swift
+var buf = [CChar](repeating: 0, count: Int(IFNAMSIZ))
+let utunPrefix = "utun".utf8CString.dropLast()
+let tunFd = ((0 ... 1024).first { (_ fd: Int32) -> Bool in var len = socklen_t(buf.count)
+    return getsockopt(fd, 2, 2, &buf, &len) == 0 && buf.starts(with: utunPrefix)
+}!
+```
+
+Set the environment variable `xray.tun.fd` (or `XRAY_TUN_FD`) to the fd number before starting Xray. This can be done from Swift/Objective-C or by exposing a Go function via gomobile bindings.
+
+Build using gomobile for iOS framework integration:
+```
+gomobile bind -target=ios

+// BandwidthSampler keeps track of sent and acknowledged packets and outputs a

+// individual packets, and are not filtered; the consumer has to filter the
+// bandwidth samples itself. In certain cases, the sampler will locally severely
+// underestimate the bandwidth, hence a maximum filter with a size of at least
+// one RTT is recommended.
+//
+// This class bases its samples on the slope of two curves: the number of bytes
+// sent over time, and the number of bytes acknowledged as received over time.
+// It produces a sample of both slopes for every packet that gets acknowledged,
+// based on a slope between two points on each of the corresponding curves. Note
+// that due to the packet loss, the number of bytes on each curve might get
+// further and further away from each other, meaning that it is not feasible to
+// compare byte values coming from different curves with each other.
+//
+// The obvious points for measuring slope sample are the ones corresponding to
+// the packet that was just acknowledged. Let us denote them as S_1 (point at
+// which the current packet was sent) and A_1 (point at which the current packet
+// was acknowledged). However, taking a slope requires two points on each line,
+// so estimating bandwidth requires picking a packet in the past with respect to
+// which the slope is measured.
+//
+// For that purpose, BandwidthSampler always keeps track of the most recently
+// acknowledged packet, and records it together with every outgoing packet.
+// When a packet gets acknowledged (A_1), it has not only information about when
+// it itself was sent (S_1), but also the information about the latest
+// acknowledged packet right before it was sent (S_0 and A_0).
+//
+// Based on that data, send and ack rate are estimated as:
+//
+//	send_rate = (bytes(S_1) - bytes(S_0)) / (time(S_1) - time(S_0))
+//	ack_rate = (bytes(A_1) - bytes(A_0)) / (time(A_1) - time(A_0))
+//
+// Here, the ack rate is intuitively the rate we want to treat as bandwidth.
+// However, in certain cases (e.g. ack compression) the ack rate at a point may
+// end up higher than the rate at which the data was originally sent, which is
+// not indicative of the real bandwidth. Hence, we use the send rate as an upper
+// bound, and the sample value is
+//
+//	rate_sample = min(send_rate, ack_rate)
+//
+// An important edge case handled by the sampler is tracking the app-limited
+// samples. There are multiple meaning of "app-limited" used interchangeably,
+// hence it is important to understand and to be able to distinguish between
+// them.
+//
+// Meaning 1: connection state. The connection is said to be app-limited when
+// there is no outstanding data to send. This means that certain bandwidth
+// samples in the future would not be an accurate indication of the link
+// capacity, and it is important to inform consumer about that. Whenever
+// connection becomes app-limited, the sampler is notified via OnAppLimited()
+// method.
+//
+// Meaning 2: a phase in the bandwidth sampler. As soon as the bandwidth
+// sampler becomes notified about the connection being app-limited, it enters
+// app-limited phase. In that phase, all *sent* packets are marked as
+// app-limited. Note that the connection itself does not have to be
+// app-limited during the app-limited phase, and in fact it will not be
+// (otherwise how would it send packets?). The boolean flag below indicates
+// whether the sampler is in that phase.
+//
+// Meaning 3: a flag on the sent packet and on the sample. If a sent packet is
+// sent during the app-limited phase, the resulting sample related to the
+// packet will be marked as app-limited.
+//
+// With the terminology issue out of the way, let us consider the question of
+// what kind of situation it addresses.
+//
+// Consider a scenario where we first send packets 1 to 20 at a regular
+// bandwidth, and then immediately run out of data. After a few seconds, we send
+// packets 21 to 60, and only receive ack for 21 between sending packets 40 and
+// 41. In this case, when we sample bandwidth for packets 21 to 40, the S_0/A_0
+// we use to compute the slope is going to be packet 20, a few seconds apart
+// from the current packet, hence the resulting estimate would be extremely low
+// and not indicative of anything. Only at packet 41 the S_0/A_0 will become 21,
+// meaning that the bandwidth sample would exclude the quiescence.
+//
+// Based on the analysis of that scenario, we implement the following rule: once
+// OnAppLimited() is called, all sent packets will produce app-limited samples
+// up until an ack for a packet that was sent after OnAppLimited() was called.
+// Note that while the scenario above is not the only scenario when the
+// connection is app-limited, the approach works in other cases too.

+// If all elements are inserted in order, all of the operations above are
+// amortized O(1) time.

+// Internally, the data structure is a deque where each element is marked as

+// element is removed, it's marked as not present, and the front of the deque is
+// cleared of elements that are not present.
+//
+// The tail of the queue is not cleared due to the assumption of entries being
+// inserted in order, though removing all elements of the queue will return it
+// to its initial state.

+// Note that this data structure is inherently hazardous, since an addition of
