 We format the code using `rustfmt`. Run `cargo fmt` prior to committing the code.
 Run `scripts/clippy.sh` to check the code for common mistakes with [Clippy].
 
-Multi-line SQL statements should be formatted using string literals,
-for example
-```
-    sql.execute(
-        "CREATE TABLE messages (
-id INTEGER PRIMARY KEY AUTOINCREMENT,
-text TEXT DEFAULT '' NOT NULL -- message text
-) STRICT",
-    )
-    .await?;
-```
-
-Do not use macros like [`concat!`](https://doc.rust-lang.org/std/macro.concat.html)
-or [`indoc!](https://docs.rs/indoc).
-Do not escape newlines like this:
-```
-    sql.execute(
-        "CREATE TABLE messages ( \
-id INTEGER PRIMARY KEY AUTOINCREMENT, \
-text TEXT DEFAULT '' NOT NULL \
-) STRICT",
-    )
-    .await?;
-```
-Escaping newlines
-is prone to errors like this if space before backslash is missing:
-```
-"SELECT foo\
- FROM bar"
-```
-Literal above results in `SELECT fooFROM bar` string.
-This style also does not allow using `--` comments.

-# Attaching a contact to a message
-
-Messengers MAY allow the user to attach a contact to a message
-in order to share it with the chat partner.
-The contact MUST be sent as a [vCard](https://datatracker.ietf.org/doc/html/rfc6350).
-
-The vCard MUST contain `EMAIL`,
-`FN` (display name),
-and `VERSION` (which version of the vCard standard you're using).
-If available, it SHOULD contain
-`REV` (current timestamp),
-`PHOTO` (avatar), and
-`KEY` (OpenPGP public key,
-in binary format,
-encoded with vanilla base64;
-note that this is different from the OpenPGP 'ASCII Armor' format).
-
-Example vCard:
-
-```
-BEGIN:VCARD
-VERSION:4.0
-EMAIL:alice@example.org
-FN:Alice Wonderland
-KEY:data:application/pgp-keys;base64,[Base64-data]
-PHOTO:data:image/jpeg;base64,[image in Base64]
-REV:20240418T184242Z
-END:VCARD
-```
-
-It is fine if messengers do include a full vCard parser
-and e.g. simply search for the line starting with `EMAIL`
-in order to get the email address.

-# Transitioning to a new e-mail address (AEAP)

-When receiving a message:
-- If the key exists, but belongs to another address
-- AND there is a `Chat-Version` header
-- AND the message is signed correctly
-- AND the From address is (also) in the encrypted (and therefore signed) headers 
-- AND the message timestamp is newer than the contact's `lastseen`
-  (to prevent changing the address back when messages arrive out of order)
-  (this condition is not that important
-  since we will have eventual consistency even without it):
-
-  Replace the contact in _all_ groups,
-  possibly deduplicate the members list,
-  and add a system message to all of these chats.
