 Bromite is [Chromium](https://www.chromium.org/Home) plus some patches for ad blocking and enhanced privacy.
 
-Bromite is only available for Android v4.1 and above.
+Bromite is only available for Android v4.4 and above.
 
-See [open issues](https://github.com/bromite/bromite/issues) for the development in progress.
+<img src="https://www.bromite.org/bromite_bromite_gh_downloads.svg" alt="downloads on Github" title="downloads on Github" />
+
+# Goals
+
+Bromite aims at providing a no-clutter browsing experience without privacy-invasive features and with the addition of a fast ad-blocking engine.
+Minimal UI changes are applied to help curbing the idea of "browser as an advertisement platform".

 # F.A.Q.
 
-## Does Google Sync work?
+## Does Google Sync/Translate/Data saver work?
 No.
 This is not a limitation of Bromite but of all Chromium-based projects in general, as general public is not allowed to use Google's APIs for free unless when using Chrome.
 
+Additionally, these features would not be privacy-friendly.
+
+## Does Bromite require root?
+No.
+
+## Is Bromite de-googled?
+
+Yes, although this has not been verified (and hardly can be) under all situations; if you were to find connections to cloud-based services please report them via the issue tracker.
+Projects which follow a strict approach on this are [Iridium](https://iridiumbrowser.de/) and [Inox patchset](https://github.com/gcarq/inox-patchset).
+
+## What is the SystemWebView?
+It is the core component of Android for all web page visualizations. For example when you access a new wifi network and need to activate it, that is using the SystemWebView. If you do not know what it is then you do not need to install it.
+
+See also [the wiki page](https://github.com/bromite/bromite/wiki/Installing-SystemWebView) for community-contributed installation instructions.
+
+## How to enable DNS-over-HTTPS?
+
+See [this wiki page](https://github.com/bromite/bromite/wiki/Enabling-DNS-over-HTTPS).
+
+## Can you add HTTPS everywhere?
+No.
+We cannot add add-ons to Bromite (merely some features).
+
+## Is Bromite on Play Store?
+No, and this is unlikely to change. Many limitations apply for submissions there, including which ads are allowed to be blocked.
+
+Bromite favors user freedom in software choice: the device is yours so you get to choose which software to run on it, end of the story.
+
+## Is Bromite on F-Droid?
+It is not on the official F-Droid repository and there are no (more) plans to submit it.
+
+You can use F-Droid client to install and receive updates via [the official Bromite F-Droid repository](https://www.bromite.org/fdroid).
+
+## Does Bromite support WebRTC?
+Yes, since version 69. While the desktop version of Chromium has an option to disable it (video/audio site settings), the Android version cannot.
+
+# Features
+
+* native adblock engine
+* remove click-tracking and AMP from search results
+* DNS-over-HTTPS support via Google, Cloudflare, Quad9 and AdGuard servers
+* [proxy configuration page](https://github.com/bromite/bromite/wiki/ProxyConfiguration) with PAC and custom proxy lists support
+* [StartPage](https://startpage.com/), [DuckDuckGo](https://duckduckgo.com/) and [Qwant](https://www.qwant.com/) search engines
+* chrome flags to disable custom intents and clear session on exit
+* always-incognito mode
+* completely removed safe browsing and other privacy-unfriendly features
+* anti-fingerprinting mitigations for canvas, audio, client rects, webGL and sensor APIs
+* use fixed User-Agent to conceal real model and browser version
+* privacy enhancement patches from [Iridium](https://iridiumbrowser.de/), [Inox patchset](https://github.com/gcarq/inox-patchset), [Brave](https://brave.com/) and [ungoogled-chromium](https://github.com/Eloston/ungoogled-chromium) projects
+* security enhancement patches from [GrapheneOS](https://github.com/GrapheneOS) project
+
+## Features not related to privacy
+* import/export bookmarks
+* allow playing videos in background tabs and disable pause on switching tabs
+* all codecs included (proprietary, open H.264 etc.)
+* [AV1 codec support](https://github.com/bromite/bromite/wiki/AV1-support)
+* built with official speed optimizations
+
+You can inspect all functionality/privacy changes by reading the patches: https://github.com/bromite/bromite/tree/master/build/patches
+
+# Privacy limitations
+
+Bromite's privacy features, including anti-fingerprinting mitigations (which can be easily circumvented), **are not to be considered useful for journalists and people living in countries with freedom limitations**, please look at [Tor Browser](https://2019.www.torproject.org/projects/torbrowser.html.en) in such cases.
+
 # Releases
 
-A build server goes through the very lengthy build operation and then new versions are available in this project as [releases](https://github.com/bromite/bromite/releases).
+All built versions are available as [releases](https://github.com/bromite/bromite/releases); the [official website](https://www.bromite.org/) points to those releases and - when browsing via Android - it will automatically select the one apt for your device (or none otherwise).
 
-Each tag corresponds to a Chromium release tag.
+Each tag corresponds to a Chromium Stable release tag.
+
+Bromite is currently built for ARM, ARM64 and x86 and for the Android SDK versions 19 and 21; [Bromite SystemWebView](https://www.bromite.org/system_web_view) is provided as well (SDK21+).
+For every Bromite build you can always find a matching [vanilla Chromium](https://www.bromite.org/chromium) build which is used for example to verify which issues are specific to Bromite or not.
+
+All official releases are also available through the [official third-party F-Droid repository](https://www.bromite.org/fdroid).
+
+## Integrity and authenticity
+
+You can verify the integrity of a downloaded APK file from this project with any `sha256sum`-compatible tool by downloading the corresponding `brm_X.Y.Z.sha256.txt` or `chr_X.Y.Z.sha256.txt` file, where X.Y.Z is the release version number. Example:
+```
+$ sha256sum --check brm_68.0.3440.54.sha256.txt
+arm64_SystemWebView.apk: OK
+arm64_ChromePublic.apk: OK
+arm64_ChromeModernPublic.apk: OK
+```
+
+If you prefer an UI-based tool, you might want to look into [GtkHash](https://github.com/tristanheaven/gtkhash).
+
+You can verify authenticity, e.g. that the author ([csagan5](https://github.com/csagan5)) released the file, by using gpg2:
+```
+$ gpg2 --quiet --verify brm_68.0.3440.54.sha256.txt.asc
+gpg: assuming signed data in 'brm_68.0.3440.54.sha256.txt'
+gpg: Signature made Sun 08 Jul 2018 04:22:52 PM CEST using RSA key ID D85DC0C5
+gpg: Good signature from "csagan5 <32685696+csagan5@users.noreply.github.com>"
+```
+
+You can download csagan5's public GnuPG key from here: [csagan5.asc](./csagan5.asc).
+
+**NOTE:** releases before v68 did not have published signed hashes files.
 
 # How to build
 
-The [bromite main repository](https://github.com/bromite/bromite) contains tags for each corresponding Chromium release (see https://chromium.googlesource.com/chromium/src.git).
+The [Bromite main repository](https://github.com/bromite/bromite) contains tags for each corresponding Chromium release (see https://chromium.googlesource.com/chromium/src.git).
 
 Please refer to [official Chromium build documentation](https://www.chromium.org/developers/how-tos/get-the-code) to get started on how to build Chromium; if you can build Chromium for Android, you can build Bromite.
 
+The GN args used to build Bromite are available here: [GN_ARGS](./build/GN_ARGS).
+The patches are to be applied second the order specified in the `bromite_patches_list.txt` file (you can use `git am`).
+
+## How to build the filters
+
+See upstream documentation: https://github.com/chromium/chromium/blob/master/components/subresource_filter/FILTER_LIST_GENERATION.md
+
+Bromite uses an unindexed filter file, which is periodically published at https://github.com/bromite/filters

+Subject: Enable -fwrapv in Clang for non-UBSan builds
+
+Using -fwrapv (notably only when not using signed integer overflow checking -
+since it will override it and result in not performing checks) is just common
+sense since it eliminates the chance of security vulnerabilities being
+introduced by optimizations based on signed overflow being undefined.
+That has happened before, and those optimizations don't even add up to a 0.1%
+performance increase for this kind of software. It's not worth having.
+The Linux kernel passes -fwrapv and also -fno-strict-aliasing to disable those
+dangerous optimizations (since there is so much incorrect code they can break).
+In fact, it is easy to point to dozens of known examples of invalid code that
+could potentially be broken by those optimizations.
+
+It is not acceptable for projects to be using optimizations that are known to
+be broken with a bunch of code in their tree.
+They put barely any effort into even fixing the known cases.
+Chromium has blacklists for UBSan for 'false positives' (none of which are
+actually false positives, but rather "undefined, but not a bug beyond
+potentially being broken by optimizations or even code generation without
+them") and also for components too full of these bugs for them to currently
+want to bother with it. That includes a bunch of signed overflow issues
+(there is sadly no detection for aliasing violations, which are fairly common,
+but not that common).
+
+Ideally, -fwrapv could be always passed, but unfortunately the way it is
+implemented has silly interactions with other switches.
+The reason it would still make sense to pass it is because due to their UBSan
+blacklists, they get far from full coverage with it, so -fwrapv would still
+be better than nothing where it's not being used.
+
+Since -fwrapv makes signed integer overflow well-defined, Clang will disable
+the UBSan checks for signed integer overflow, including in the
+production-oriented trapping mode used for hardening.

+From: csagan5 <32685696+csagan5@users.noreply.github.com>
+Date: Fri, 30 Mar 2018 10:09:03 +0200
+Subject: Multiple fingerprinting mitigations for canvas, text and client
+ rectangles
+
+1. getClientRects, getBoundingClientRect, measureText: add fingerprinting mitigation
+
+Scale the result of Range::getClientRects, Element::getBoundingClientRect and
+Canvas::measureText by a random +/-3/1000000th of the original value for each
+float in the returned Rect/Quad.
+
+It contains improvements from ungoogled-chromium which add two flags:
+1. --fingerprinting-client-rects-noise to enable fingerprinting deception for Range::getClientRects and Element::getBoundingClientRect
+2. --fingerprinting-canvas-measuretext-noise to enable fingerprinting deception for Canvas::measureText
+
+2. Canvas: fingerprinting mitigations for image data and webGL
+
+Disable webGL renderer info and modify the color data returned by ToBlob,
+ToDataURL and getImageData so that it will contain randomly manipulated
+pixels (maximum 20) that slightly change the color of the R,G,B components
+without a visible effect.
+
+Credits to Slaviro (https://github.com/Slaviro) for coming up with a better
+approach to change color components.
+
+Added flag --fingerprinting-canvas-image-data-noise to disable Canvas image data fingerprinting deception
