-# Building Proton Mail Bridge and Import-Export app
+# Building ProtonMail Bridge app
 
 ## Prerequisites
-* 64-bit AMD OS:
-    - the go-rfc5322 module cannot currently be compiled for 32-bit OSes
-    - the Apple M1 builds are not supported yet due to dependencies
 * Go 1.13
 * Bash with basic build utils: make, gcc, sed, find, grep, ...
 * For Windows it is recommended to use MinGW 64bit shell from [MSYS2](https://www.msys2.org/)
 * GCC (linux, windows) or Xcode (macOS)
 * Windres (windows)
-* libglvnd and libsecret development files (linux)
 
 To enable the sending of crash reports using Sentry please set the
 `main.DSNSentry` value with the client key of your sentry project before build.
 Otherwise, the sending of crash reports will be disabled.
 
 ## Build
-In order to build Bridge or Import-Export app with Qt interface we are using
-[Qt Go Binding](https://github.com/therecipe/qt).  The dependencies and
-installation of this tool is part of `make build` target.  If you have issues
-with installation of therecipe/qt we recommend to follow [this
-wiki](https://github.com/therecipe/qt/wiki/Installation-on-Linux)
-
-Please note that `$(go env GOPATH)/bin` must be in your `PATH` to ensure
-binaries installed by `therecipe/qt` (such as `qtdeploy`) are found. Also,
-before you start build **on Windows**, please unset the `MSYSTEM` variable
-
+* for Windows please unset the `MSYSTEM` variable

-
-#### Build Bridge without GUI
-* If you need to build bridge without Qt dependencies, you can do so by running
-
-```bash
-make build-nogui
-```
-
-* Bridge without GUI will start by default without any interface (i.e., there is no way to add or remove client, get bridge password, etc)
-* Bridge always has the option (whether built with Qt or without) to use a CLI interface by starting it with the argument `-c`
-* NOTE: You still need to setup supported keychain on your system

-    * for `darwin`, the application will be created with name of the project directory (e.g `proton-bridge.app`)
-
-### Launchers
-Launchers are only included in official distributions and provide the public
-key used to verify signed app binaries, allowing the automatic update feature.
-See README for more information.
-
-### Tags
-Note that repository contains both Bridge and Import-Export apps and they are
-not released together. Therefore, each app has own tag prefix. Bridge tags
-starts with `br-` and Import-Export tags starts with `ie-`. Both tags continue
-with semantic versioning `MAJOR.MINOR.PATCH`. An example of full tag is
-`br-1.4.4` or `ie-1.1.2` (current versions in October 2020).

-## Description Import-Export app
-Proton Mail Import-Export app for importing and exporting messages.
-
-To transfer messages, firstly log in using your Proton Mail credentials.
-For import, expand your account, and pick the address to which to import
-messages from IMAP server or local EML or MBOX files. For export, pick
-the whole account or only a specific address. Then, in both cases,
-configure transfer rules (match source and target mailboxes, set time
-range limits and so on) and hit start. Once the transfer is complete,
-check the results.
-
-More details [on the public website](https://protonmail.com/import-export).
-
-The Import-Export app is developed in separate branch `master-ie`.
-
-## Launchers
-Launchers are binaries used to run the Proton Mail Bridge or Import-Export apps.
-
-Official distributions of the Proton Mail Bridge and Import-Export apps contain
-both a launcher and the app itself. The launcher is installed in a protected
-area of the system (i.e. an area accessible only with admin privileges) and is
-used to run the app. The launcher ensures that nobody tampered with the app's
-files by verifying their signature using a hardcoded public key. App files are
-placed in regular userspace and are signed by Proton's private key. This
-feature enables the app to securely update itself automatically without asking
-the user for a password.
 
 ## Keychain
-You need to have a keychain in order to run the Proton Mail Bridge. On Mac or
-Windows, Bridge uses native credential managers. On Linux, use `secret-service` freedesktop.org API
-(e.g. [Gnome keyring](https://wiki.gnome.org/Projects/GnomeKeyring/))

-## Files
-### Database
-The database stores metadata necessary for presenting messages and mailboxes to an email client:
-- Linux: `~/.cache/protonmail/bridge/<cacheVersion>/mailbox-<userID>.db` (unless `XDG_CACHE_HOME` is set, in which case that is used as your `~`)
-- macOS: `~/Library/Caches/protonmail/bridge/<cacheVersion>/mailbox-<userID>.db`
-- Windows: `%LOCALAPPDATA%\protonmail\bridge\<cacheVersion>\mailbox-<userID>.db`
 
-### Preferences
-User preferences are stored in json at the following location:
-- Linux: `~/.config/protonmail/bridge/prefs.json`
-- macOS: `~/Library/ApplicationSupport/protonmail/bridge/prefs.json`
-- Windows: `%APPDATA%\protonmail\bridge\prefs.json`
-
-### IMAP Cache
-The currently subscribed mailboxes are held in a json file:
-- Linux: `~/.cache/protonmail/bridge/<cacheVersion>/user_info.json` (unless `XDG_CACHE_HOME` is set, in which case that is used as your `~`)
-- macOS: `~/Library/Caches/protonmail/bridge/<cacheVersion>/user_info.json`
-- Windows: `%LOCALAPPDATA%\protonmail\bridge\<cacheVersion>\user_info.json`
-
-### Lock file
-Bridge utilises an on-disk lock to ensure only one instance is run at once. The lock file is here: 
-- Linux: `~/.cache/protonmail/bridge/<cacheVersion>/bridge.lock` (unless `XDG_CACHE_HOME` is set, in which case that is used as your `~`)
-- macOS: `~/Library/Caches/protonmail/bridge/<cacheVersion>/bridge.lock`
-- Windows: `%LOCALAPPDATA%\protonmail\bridge\<cacheVersion>\bridge.lock`
-
-### TLS Certificate and Key
-When bridge first starts, it generates a unique TLS certificate and key file at the following locations:
-- Linux: `~/.config/protonmail/bridge/{cert,key}.pem` (unless `XDG_CONFIG_HOME` is set, in which case that is used as your `~/.config`)
-- macOS: `~/Library/ApplicationSupport/protonmail/bridge/{cert,key}.pem`
-- Windows: `%APPDATA%\protonmail\bridge\{cert,key}.pem`

-# Update mechanism of Bridge
-
-There are mulitple options how to change version of application:
-* Automatic in-app update
-* Manual in-app update
-* Manual install
-
-In-app update ends with restarting bridge into new version. Automatic in-app
-update is downloading, verifying and installing the new version immediatelly
-without user confirmation. For manual in-app update user needs to confirm first.
-Update is done from special update file published on website.
-
-The manual installation requires user to download, verify and install manually
-using installer for given OS.
-
-The bridge is installed and executed differently for given OS:
-
-* Windows and Linux apps are using launcher mechanism:
-    * There is system protected installation path which is created on first
-      install. It contains bridge exe and launcher exe. When users starts
-      bridge the launcher is executed first. It will check update path compare
-      version with installed one. The newer version then is then executed.
-    * Update mechanism means to replace files in update folder which is located
-      in user space.
-
-* macOS app does not use launcher
-    * No launcher, only one executable
-    * In-App udpate replaces the bridge files in installation path directly
