Like I mentioned in the question, a major problem with EdXposed is *lack of documentation*. There is an [[OFFICIAL] EdXposed - The successor of Xposed [Oreo/Pie/Q/R, 2020/07/19]](https://forum.xda-developers.com/xposed/development/official-edxposed-successor-xposed-t4070199) thread opened by [Mlgmxyysd](https://forum.xda-developers.com/member.php?u=8430637), one of EdXposed main developers but, sadly doesn't provide any useful information.
**Updated on 06 January 21 , likely the last update from me..feel free to improve**
* EdXposed canary version supports Android 11 for the last couple of months but [official support](https://github.com/ElderDrivers/EdXposed/releases/tag/v0.5.1.3) has been announced a fortnight ago (v0.5.1.3)
* Information is valid as of writing. Things will change and if you want to improve the answer by editing or posting a new answer, please do.
* This is NOT a support thread. I am not frequenting SE,and therefore cannot answer your questions.
----------
**Pre-requisites** (need to be updated from sources or as prompted by EdXPosed manager).
* Magisk v21 + , with Magisk Manager from [official Magisk thread](https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445). Note that some devices play well with certain versions of Magisk so it's better to search device threads in XDA for appropriate Magisk version for your device.
* Riru-core latest release from Magisk modules or from [GitHub](https://github.com/RikkaApps/Riru/releases) (Please read the subsequent sections and choose the relevant option)
* EdXposed *canary* drivers YAHFA/Sandhook from [EdXposed manager v4.5.7](https://github.com/ElderDrivers/EdXposedManager/releases). And the EdXposed manager
**Important changes that dictate which method to use in the installation section that follows (also applicable to **OLDER** Android versions)**
* Obviously you have a rooted device running Android 11 , with Magisk installed. For *most* Android 11 devices including my Pixel 4a, Android 11 support was possible by using a [canary version of Magisk(21004)](https://superfiles.co/download/NZ0nclfi/Magisk-Canary-Android-11.apk) ( I added that third party link because the [official page](https://github.com/topjohnwu/magisk_files/find/canary) only links to the latest). The latest release (21200) offers a better support.
So broadly speaking you have two alternatives
* Magisk canary (21004) which can **only** be used with Sandhook or YAHFA version 4.x, for Android 11 or YAHFA v 0.4.x.x for older versions
* Magisk canary (21200)(or corresponding stable for older Androids) which can **only** be used with Sandhook or YAHFA version 5 for e.g. YAHFA v0.**5**.0.6
* Reason of being aware of this that this is linked to changes in Riru and corresponding YAHFA or Sandhook drivers. Riru v 21.x can **only** be used with the **first** option and Riru v 23.x can **only** be used with **second** option
**Eeks..what's with Riru now?**
* To put it simply Riru v 23.x made a ton of changes that needed YAHFA or Sandhook drivers to be updated (which have been done). **Version 5 of YAHFA or Sandhook are Compatible with Riru V 23.x . [No backward compatibility](https://github.com/ElderDrivers/EdXposed/pull/623)**.
* This change can also affect your choice of modules. See [this](https://forum.xda-developers.com/t/app-q-xposed-gravitybox-v10-1-0-for-android-10-27-12-2020.3974497/post-84177869) for an example. Module developer may be implementing methods which **may** need to be changed. If they don't , you can't use Riru v 23.x , simple.
* On Pixel 4a ,I am using the Riru v 23.x with YAHFA v 5.x
# Installation
This being a canary version, installation is unconventional (though I have read some posts that the conventional way (see linked questions in the body of question also work on some devices)
* Install EdXposed Manager v4.5.7.
* From the canary tab download the YAHFA/ Sandhook drivers (zip) . Note that downloaded version may have a different name from the file name in canary tab.
* Install Riru-core module first from Magisk Repo. Don't reboot.
* Install downloaded YAHFA or Sandhook using install from storage option of Magisk.
* If you want to verify the status of Riru , there is an [official Riru app](https://github.com/RikkaApps/Riru/releases/download/v23.0/riru-v23.0.r235.d313e94.apk), made available by the Edxposed team.
* Reboot and profit!
**YAHFA or Sandhook drivers?**.
YAHFA is relatively slower but stable by most accounts compared to Sandhook. You would need to check XDA for what works best for your device/Android version. For me, it has been YAHFA on my earlier and current device. In addition, you may be better off installing YAHFA , if root detection is a concern. As Mlgmxyysd says in her [tweet](https://twitter.com/realMlgmXyysd/status/1309880769263710209?s=20)
> SandHook has faster boot speed, but leaves pre-compiled files in the cache, which can be detected by some apps
**Modules**
* Xposed module development isn't what it used to be so there are only a few Android 11 ready Xposed modules. The ones I care for are:
* [XPrivacy Lua](https://forum.xda-developers.com/xposed/modules/xprivacylua6-0-android-privacy-manager-t3730663). This works but not fully. Hoping for Marcel to [resume support for Android 11](https://forum.xda-developers.com/showpost.php?p=83907679&postcount=5642).
* [Gravity Box for 11-released two days ago](https://forum.xda-developers.com/t/app-r-xposed-gravitybox-v11-0-0-beta-1-for-android-11-04-01-2021.4213047/post-84225275). I installed it but haven't set it up yet but going by the feedback, it seems to be quite functional.
* [XPosed Edge Pro](https://forum.xda-developers.com/xposed/modules/xposed-edgepro-v2-0-release-t3525566). Though it hasn't been updated yet for Android 10, it works to the extent I need.
