-This is basic overview of the main bridge blocks.
-
-Note connection between IMAP/SMTP and PMAPI. IMAP and SMTP packages are in the queue to be refactored
-and we would like to try to have functionality in bridge core or bridge utilities (such as messages)
-than direct usage of PMAPI from IMAP or SMTP. Also database (BoltDB) should be moved to bridge core.

-# Communication
-
-## First login and sync
-
-When user logs in to the bridge for the first time, immediately starts the first sync.
-First sync downloads all headers of all e-mails and creates database to have proper UIDs
-and indexes for IMAP. See [database](database.md) for more information.
-
-By default, whenever it's possible, sync downloads only all e-mails maiblox which already
-have list of labels so we can construct all mailboxes (inbox, sent, trash, custom folders
-and labels) without need to download each e-mail headers many times.
-
-Note that we need to download also bodies to calculate size of the e-mail and set proper
-content type (clients uses content type for guess if e-mail contains attachment)--but only
-body, not attachment. Also it's downloaded only for the first time. After that we store
-those information in our database so next time we only sync headers, labels and so on.
-
-First sync takes some time. List of 150 messages takes about second and then we need to
-download bodies for each message. We still need to do some optimalizations. Anyway, if
-user has reasonable amount of e-mails, there is good chance user will see e-mails in the
-client right after adding account.
-
-When account is added to client, client start the sync. This sync will ask Bridge app
-for all headers (done quickly) and then starts to download all bodies and attachment.
-Unfortunately for some e-mail more than once if the same e-mail is in more mailboxes
-(e.g. inbox and all mail)--there is no way to tell over IMAP it's the same message.
-
-After successful login of client to IMAP, Bridge starts event loop. That periodicly ask
-servers (each 30 seconds) for new updates (new message, keys, …).
-

-```
-
-## IMAP IDLE extension
-
-IMAP IDLE is extension, it has to be supported by both client and server. IMAP server (in our case
-the bridge) supports it so clients can use it. It works by issuing `IDLE` command by the client and
-keeps the connection open. When the server has some update, server (the bridge) will respond to that
-by `EXISTS` (new message), `APPEND` (imported message), `EXPUNGE` (deleted message) or `MOVE` response.
-
-Even when there is connection with IDLE open, server can mark the client as inactive. Therefore,
-it's recommended the client should reissue the connection after each 29 minutes. This is not the
-real push and can fail!
-
-Our event loop is also simple pull and it will trigger IMAP IDLE when we get some new update from 
-the server. Would be good to have push from the server, but we need to wait for the support on API.
-
-RFC: https://tools.ietf.org/html/rfc2177
-
-```mermaid
-sequenceDiagram
-    participant S as Server
-    participant B as Bridge
-    participant C as Client

-    C ->> B: IMAP IDLE
-
-    loop Every 30 seconds
-        S ->> B: Checking events
-        B ->> C: IMAP response
-    end
-```
-
-## Sending e-mails
-
-E-mail are sent over standard SMTP protocol. Our bridge takes the message, encrypts and sent it
-further to our server which will then send the message to its final destination. The important
-and tricky part is encryption. See [encryption](encryption.md) or [PMEL document](https://docs.google.com/document/d/1lEBkG0DC5FOWlumInKtu4a9Cc1Eszp48ZhFy9UpPQso/edit)
-for more information.

-# Database
-
-Bridge needs to have a small database to pair our IDs with IMAP UIDs and indexes. IMAP protocol
-requires every message to have an unique UID in mailbox. In this context, mailbox is not an account,
-but a folder or label. This means that one message can have more UIDs, one for each mailbox (folder), 
-and that two messages can have the same UID, but each for different mailbox (folder).
-
-IMAP index is just an index. Look at it like to an array: `["UID1", "UID2", "UID3"]`. We can access
-message by UID or index; for example index 2 and UID `UID2`. When this message is deleted, we need
-to re-index all following messages. The array will look now like `["UID1", "UID3"]` and the last
-message can be accessed by index 2 or UID `UID3`.
-
-See RFCs for more information:
-
-* https://tools.ietf.org/html/rfc822
-* https://tools.ietf.org/html/rfc3501
-
-Our database is currently built on BBolt and have those buckets (key-value storage):
-
-* Message metadata bucket:
-
-    * `[metadataBucket][API_ID] -> pmapi.Message{subject, from, to, size, other headers...}` (without body or attachment)

-* Mapping buckets

-# Encryption
-
-Encryption is done in PMAPI, bridge utils and bridge itself. The best would be to keep encryption
-in PMAPI and bridge utils (in package such as messages). All packages are using our high-level
-GopenPGP library on top of OpenPGP.
-
-## `gopenpgp.KeyRing`
-
-We use one `KeyRing` per address. Our usage then contains all keys for specific address. Primary
-key is always on the first position, then there old ones to be able to decrypt last e-mail.
-OpenPGP encrypts given message with all available keys, so we need to first get first (primary)
-key for encryption to have message encrypted only once with primary key.

-# Update mechanism of Bridge
-
-There are multiple 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 immediately
-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 update replaces the bridge files in installation path directly
