 # MsQuic
 
 `System.Net.Quic` depends on [MsQuic](https://github.com/microsoft/msquic), Microsoft, cross-platform, native implementation of the [QUIC](https://datatracker.ietf.org/wg/quic/about/) protocol.
-Currently, `System.Net.Quic` depends on [**msquic@26cff1a8de7890cf7ff77709ee14b51bc84e330e**](https://github.com/microsoft/msquic/commit/26cff1a8de7890cf7ff77709ee14b51bc84e330e) revision.
+Currently, `System.Net.Quic` depends on [**msquic@3e40721bff04845208bc07eb4ee0c5e421e6388d**](https://github.com/microsoft/msquic/commit/3e40721bff04845208bc07eb4ee0c5e421e6388d) revision.
 
 ## Usage
 
+MsQuic library in now being published so there's no need to compile it yourself.
+
+For a reference, the packaging repository is in https://github.com/dotnet/msquic.
+
+### Windows
+Prerequisites:
+- Latest [Windows Insider Builds](https://insider.windows.com/en-us/), Insiders Fast build. This is required for SChannel support for QUIC.
+  - To confirm you have a new enough build, run winver on command line and confirm you version is greater than Version 2004 (OS Build 20145.1000).
+- Turned on TLS 1.3
+  - It is turned on by default, to confirm you can check the appropriate registry `Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols` (empty means default which means enabled).
+
+During the build, the `msquic.dll` is automatically downloaded and placed in correct directories in order to be picked up by the runtime. It is also published as part of the runtime for Windows.
+
+### Linux
+
+On Linux, `libmsquic` is published via Microsoft official Linux package repository `packages.microsoft.com`. In order to consume it, you have to add it manually, see https://docs.microsoft.com/en-us/windows-server/administration/linux-package-repository-for-microsoft-software. After that, you should be able to install it via the package manager of your distro, e.g. for Ubuntu:
+```
+apt install libmsquic
+```
+
 ### Build MsQuic
 
 [MsQuic build docs](https://github.com/microsoft/msquic/blob/main/docs/BUILD.md)
+You might want to test some `msquic` changes which hasn't propagated into the released package. For that, you need to build `msquic` yourself.
