+## Why privacy matters
+
+Everyone should care about privacy and security of their communications - innocuous conversations can put you in danger even if there is nothing to hide.
+
+One of the most shocking stories is the experience of [Mohamedou Ould Salahi](https://en.wikipedia.org/wiki/Mohamedou_Ould_Slahi) that he wrote about in his memoir and that is shown in The Mauritanian movie. He was put into Guantanamo camp, without trial, and was tortured there for 15 years after a phone call to his relative in Afghanistan, under suspicion of being involved in 9/11 attacks, even though he lived in Germany for the 10 years prior to the attacks.
+
+It is not enough to use an end-to-end encrypted messenger, we all should use the messengers that protect the privacy of our personal networks - who we are connected with.
+
+## SimpleX approach to privacy and security
+
+### Complete privacy of your identity, profile, contacts and metadata
+
+**Unlike any other existing messaging platform, SimpleX has no identifiers assigned to the users** - not even random numbers. This protects the privacy of who are you communicating with, hiding it from SimpleX platform servers and from any observers. [Read more](./docs/SIMPLEX.md#full-privacy-of-your-identity-profile-contacts-and-metadata).
+
+### The best protection against spam and abuse
+
+As you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address. [Read more](./docs/SIMPLEX.md#the-best-protection-against-spam-and-abuse).
+
+### Complete ownership, control and security of your data
+
+SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received. [Read more](./docs/SIMPLEX.md#complete-ownership-control-and-security-of-your-data).
+
+### Users own SimpleX network
+
+You can use SimpleX with your own servers and still communicate with people using the servers that are pre-configured in the apps or any other SimpleX servers. [Read more](./docs/SIMPLEX.md#users-own-simplex-network).
+
+## Frequently asked questions
+
+1. _How SimpleX can deliver messages without any user identifiers?_ See [v2 release annoucement](./blog/20220511-simplex-chat-v2-images-files.md#the-first-messaging-platform-without-user-identifiers) explaining how SimpleX works.
+
+2. _Why should I not just use Signal?_ Signal is a centralised platform that uses phone numbers to identify its users and their contacts. It means that while the content of your messages on Signal is protected with robust end-to-end encryption, there is a large amount of meta-data visible to Signal - who you talk with and when.
+
+3. _How is it different from Matrix, Session, Ricochet, Cwtch, etc., that also don't require user identites?_ Although these platforms do not require a _real identity_, they do rely on anonymous user identities to deliver messages – it can be, for example, an identity key or a random number. Using a persistent user identity, even anonymous, creates a risk that user's connection graph becomes known to the observers and/or service providers, and it can lead to de-anonymizing some users. If the same user profile is used to connect to two different people via any messenger other than SimpleX, these two people can confirm if they are connected to the same person - they would use the same user identifier in the messages. With SimpleX there is no meta-data in common between your conversations with different contacts - the quality that no other messaging platform has.

+
+## Make a private connection
+
+You need to share a link or scan a QR code (in person or during a video call) to make a connection and start messaging.
+
+The channel through which you share the link does not have to be secure - it is enough that you can confirm who sent you the message and that your SimpleX connection is established.

+## SimpleX Platform design
 
-## Disclaimer
+SimpleX is a client-server network with a unique network topology that uses redundant, disposable message relay nodes to asynchronously pass messages via unidirectional (simplex) message queues, providing recipient and sender anonymity.
 
-SimpleX Chat implements a new network topology for asynchronous communication combining the advantages and avoiding the disadvantages of federated and P2P networks.
+Unlike P2P networks, all messages are passed through one or several server nodes, that do not even need to have persistence. In fact, the current [SMP server implementation](https://github.com/simplex-chat/simplexmq#smp-server) uses in-memory message storage, persisting only the queue records. SimpleX provides better metadata protection than P2P designs, as no global participant identifiers are used to deliver messages, and avoids [the problems of P2P networks](./docs/SIMPLEX.md#comparison-with-p2p-messaging-protocols).
 
-[SimpleXMQ security model](https://github.com/simplex-chat/simplexmq/blob/master/protocol/overview-tjr.md) had many improvements in v1.0.0; the implementation has not been audited yet.
+Unlike federated networks, the server nodes **do not have records of the users**, **do not communicate with each other** and **do not store messages** after they are delivered to the recipients. There is no way to discover the full list of servers participating in SimpleX network. This design avoids the problem of metadata visibility that all federated networks have and better protects from the network-wide attacks.
 
-We use SimpleX Chat all the time, but you may find some bugs. We would really appreciate if you use it and let us know anything that needs to be fixed or improved.
+Only the client devices have information about users, their contacts and groups.
 
-## Network topology
+See [SimpleX whitepaper](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md) for more information on platform objectives and technical design.
 
-SimpleX is a client-server network that uses redundant, disposable nodes to asynchronously pass messages via message queues, providing receiver and sender anonymity.
+See [SimpleX Chat Protocol](./docs/protocol/simplex-chat.md) for the format of messages sent between chat clients over [SimpleX Messaging Protocol](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/simplex-messaging.md).
 
-Unlike P2P networks, all messages are passed through one or several (for redundancy) servers, that do not even need to have persistence (in fact, the current [SMP server implementation](https://github.com/simplex-chat/simplexmq#smp-server) uses in-memory message storage, persisting only the queue records) - it provides better metadata protection than P2P designs, as no global participant ID is required, and avoids many [problems of P2P networks](https://github.com/simplex-chat/simplex-chat/blob/master/simplex.md#comparison-with-p2p-messaging-protocols).
+## Privacy: technical details and limitations
 
-Unlike federated networks, the participating server nodes **do not have records of the users**, **do not communicate with each other**, **do not store messages** after they are delivered to the recipients, and there is no way to discover the full list of participating servers. SimpleX network avoids the problem of metadata visibility that federated networks have and better protects the network, as servers do not communicate with each other. Each server node provides unidirectional "dumb pipes" to the users, that do authorization without authentication, having no knowledge of the the users or their contacts. Each queue is assigned two Ed448 keys - one for receiver and one for sender - and each queue access is authorized with a signature created using a respective key's private counterpart.
+SimpleX Chat is a work in progress – we are releasing improvements as they are ready. You have to decide if the current state is good enough for your usage scenario.
 
-The routing of messages relies on the knowledge of client devices how user contacts and groups map at any given moment of time to these disposable queues on server nodes.
+What is already implemented:
 
-## Terminal chat features
+1. Instead of user profile identifiers used by all other platforms, even the most private ones, SimpleX uses pairwise per-queue identifiers (2 addresses for each unidirectional message queue, with an optional 3rd address for push notificaitons on iOS, 2 queues in each connection between the users). It makes observing the network graph on the application level more difficult, as for `n` users there can be up to `n * (n-1)` message queues.
+2. End-to-end encryption in each message queue using [NaCl cryptobox](https://nacl.cr.yp.to/box.html). This is added to allow redundancy in the future (passing each message via several servers), to avoid having the same ciphertext in different queues (that would only be visible to the attacker if TLS is compromised). The encryption keys used for this encryption are not rotated, instead we are planning to rotate the queues. Curve25519 keys are used for key negotiation.
+3. [Double ratchet](https://signal.org/docs/specifications/doubleratchet/) end-to-end encryption in each conversation between two users (or group members). This is the same algorithm that is used in Signal and many other messaging apps; it provides OTR messaging with forward secrecy (each message is encrypted by its own ephemeral key), break-in recovery (the keys are frequently re-negotiated as part of the message exchange). Two pairs of Curve448 keys are used for the initial key agreement, initiating party passes these keys via the connection link, accepting side - in the header of the confirmation message.
+4. Additional layer of encryption using NaCL cryptobox for the messages delivered from the server to the recipient. This layer avoids having any ciphertext in common between sent and received traffic of the server inside TLS (and there are no identifiers in common as well).
+5. Several levels of content padding to frustrate message size attacks.
+6. Starting from v2 of SMP protocol (the current version is v4) all message metadata, including the time when the message was received by the server (rounded to a second) is sent to the recipients inside an encrypted envelope, so even if TLS is compromised it cannot be observed.
+7. Only TLS 1.2/1.3 are allowed for client-server connections, limited to cryptographic algorithms: CHACHA20POLY1305_SHA256, Ed25519/Ed448, Curve25519/Curve448.
+8. To protect against replay attacks SimpleX servers require [tlsunique channel binding](https://www.rfc-editor.org/rfc/rfc5929.html) as session ID in each client command signed with per-queue ephemeral key.
+9. To protect your IP address all SimpleX Chat clients support accessing messaging servers via Tor - see [v3.1 release announcement](./blog/20220808-simplex-chat-v3.1-chat-groups.md) for more details.

-- Sending files to contacts and groups.
-- User contact addresses - establish connections via multiple-use contact links.
-- Messages persisted in a local SQLite database.
-- Auto-populated recipient name - just type your messages to reply to the sender once the connection is established.
-- Demo SMP servers available and pre-configured in the app - or you can [deploy your own server](https://github.com/simplex-chat/simplexmq#using-smp-server-and-smp-agent).
-- No global identity or any names visible to the server(s), ensuring full privacy of your contacts and conversations.
-- Two layers of E2E encryption (double-ratchet for duplex connections, using X3DH key agreement with ephemeral Curve448 keys, and NaCl crypto_box for SMP queues, using Curve25519 keys) and out-of-band passing of recipient keys (see [How to use SimpleX chat](#how-to-use-simplex-chat)).
-- Message integrity validation (via including the digests of the previous messages).
-- Authentication of each command/message by SMP servers with automatically generated Ed448 keys.
-- TLS 1.3 transport encryption.
-- Additional encryption of messages from SMP server to recipient to reduce traffic correlation.
+We plan to add soon:
 
-Public keys involved in key exchange are not used as identity, they are randomly generated for each contact.
+1. Message queue rotation. Currently the queues created between two users are used until the contact is deleted, providing a long-term pairwise identifiers of the conversation. We are planning to add queue rotation to make these identifiers termporary and rotate based on some schedule TBC (e.g., every X messages, or every X hours/days).
+2. Local database encryption. Currently the local chat database stored on your device is not encrypted.
+3. Message "mixing" - adding latency to message delivery, to protect against traffic correlation by message time.
+4. Independent implementation audit.
 
-See [Encryption Primitives Used](https://github.com/simplex-chat/simplexmq/blob/master/protocol/overview-tjr.md#encryption-primitives-used) for technical details.

+You can:
 
-## 🚀 Installation
+- use SimpleX Chat library to integrate chat functionality into your mobile apps.
+- create chat bots and services in Haskell - see [simple](./apps/simplex-bot/) and more [advanced chat bot example](./apps/simplex-bot-advanced/).
+- create chat bots and services in any language running SimpleX Chat terminal CLI as a local WebSocket server. See [TypeScript SimpleX Chat client](./packages/simplex-chat-client/) and [JavaScipt chat bot example](./packages/simplex-chat-client/typescript/examples/squaring-bot.js).
+- run [simplex-chat terminal CLI](./docs/CLI.md) to execute individual chat commands, e.g. to send messages as part of shell script execution.
 
-### Download chat client
-
-#### Linux and MacOS
-
-To **install** or **update** `simplex-chat`, you should run the install script. To do that, use the following cURL or Wget command:
-
-```sh
-curl -o- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/install.sh | bash
-```
-
-```sh
-wget -qO- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/install.sh | bash
-```
-
-Once the chat client downloads, you can run it with `simplex-chat` command in your terminal.
-
-Alternatively, you can manually download the chat binary for your system from the [latest stable release](https://github.com/simplex-chat/simplex-chat/releases) and make it executable as shown below.
-
-```sh
-chmod +x <binary>
-mv <binary> ~/.local/bin/simplex-chat
-```
-
-(or any other preferred location on `PATH`).
-
-On MacOS you also need to [allow Gatekeeper to run it](https://support.apple.com/en-us/HT202491).
-
-#### Windows
-
-```sh
-move <binary> %APPDATA%/local/bin/simplex-chat.exe
-```
-
-### Build from source
-
-> **Please note:** to build the app use source code from [stable branch](https://github.com/simplex-chat/simplex-chat/tree/stable).
-
-#### Using Docker
-
-On Linux, you can build the chat executable using [docker build with custom output](https://docs.docker.com/engine/reference/commandline/build/#custom-build-outputs):
-
-```shell
-$ git clone git@github.com:simplex-chat/simplex-chat.git
-$ cd simplex-chat
-$ git checkout stable
-$ DOCKER_BUILDKIT=1 docker build --output ~/.local/bin .
-```
-
-> **Please note:** If you encounter `` version `GLIBC_2.28' not found `` error, rebuild it with `haskell:8.10.4-stretch` base image (change it in your local [Dockerfile](Dockerfile)).
-
-#### Using Haskell stack
-
-Install [Haskell stack](https://docs.haskellstack.org/en/stable/README/):
-
-```shell
-curl -sSL https://get.haskellstack.org/ | sh
-```
-
-and build the project:
-
-```shell
-$ git clone git@github.com:simplex-chat/simplex-chat.git
-$ cd simplex-chat
-$ git checkout stable
-$ stack install
-```
-
-## Usage
-
-### Running the chat client
-
-To start the chat client, run `simplex-chat` from the terminal.
-
-By default, app data directory is created in the home directory (`~/.simplex`, or `%APPDATA%/simplex` on Windows), and two SQLite database files `simplex_v1_chat.db` and `simplex_v1_agent.db` are initialized in it.
-
-To specify a different file path prefix for the database files use `-d` command line option:
-
-```shell
-$ simplex-chat -d alice
-```
-
-Running above, for example, would create `alice_v1_chat.db` and `alice_v1_agent.db` database files in current directory.
-
-Three default SMP servers are hosted on Linode - they are [pre-configured in the app](https://github.com/simplex-chat/simplex-chat/blob/master/src/Simplex/Chat/Options.hs#L42).
-
-If you deployed your own SMP server(s) you can configure client via `-s` option:
-
-```shell
-$ simplex-chat -s smp://LcJUMfVhwD8yxjAiSaDzzGF3-kLG4Uh0Fl_ZIjrRwjI=@smp.example.com
-```
-
-Base64url encoded string preceding the server address is the server's offline certificate fingerprint which is validated by client during TLS handshake.
-
-You can still talk to people using default or any other server - it only affects the location of the message queue when you initiate the connection (and the reply queue can be on another server, as set by the other party's client).
-
-Run `simplex-chat -h` to see all available options.
-
-### How to use SimpleX chat
-
-Once you have started the chat, you will be prompted to specify your "display name" and an optional "full name" to create a local chat profile. Your display name is an alias for your contacts to refer to you by - it is not unique and does not serve as a global identity. If some of your contacts chose the same display name, the chat client adds a numeric suffix to their local display name.
-
-The diagram below shows how to connect and message a contact:
-
-<div align="center">
-  <img align="center" src="images/how-to-use-simplex.svg">
-</div>
-
-Once you've set up your local profile, enter `/c` (for `/connect`) to create a new connection and generate an invitation. Send this invitation to your contact via any other channel.
-
-You are able to create multiple invitations by entering `/connect` multiple times and sending these invitations to the corresponding contacts you'd like to connect with.
-
-The invitation can only be used once and even if this is intercepted, the attacker would not be able to use it to send you the messages via this queue once your contact confirms that the connection is established. See agent protocol for explanation of [invitation format](https://github.com/simplex-chat/simplexmq/blob/master/protocol/agent-protocol.md#connection-request).
-
-The contact who received the invitation should enter `/c <invitation>` to accept the connection. This establishes the connection, and both parties are notified.
-
-They would then use `@<name> <message>` commands to send messages. You may also just start typing a message to send it to the contact that was the last.
-
-Use `/help` in chat to see the list of available commands.
-
-### Groups
-
-To create a group use `/g <group>`, then add contacts to it with `/a <group> <name>`. You can then send messages to the group by entering  `#<group> <message>`. Use `/help groups` for other commands.
-
-![simplex-chat](./images/groups.gif)
-
-> **Please note**: the groups are not stored on any server, they are maintained as a list of members in the app database to whom the messages will be sent.
-
-### Sending files
-
-You can send a file to your contact with `/f @<contact> <file_path>` - the recipient will have to accept it before it is sent. Use `/help files` for other commands.
-
-![simplex-chat](./images/files.gif)
-
-You can send files to a group with `/f #<group> <file_path>`.
-
-### User contact addresses
-
-As an alternative to one-time invitation links, you can create a long-term address with `/ad` (for `/address`). The created address can then be shared via any channel, and used by other users as a link to make a contact request with `/c <user_contact_address>`.
-
-You can accept or reject incoming requests with `/ac <name>` and `/rc <name>` commands.
-
-User address is "long-term" in a sense that it is a multiple-use connection link - it can be used until it is deleted by the user, in which case all established connections would still remain active (unlike how it works with email, when changing the address results in people not being able to message you).
-
-Use `/help address` for other commands.
-
-![simplex-chat](./images/user-addresses.gif)
-
-### Access chat history
-
-SimpleX chat stores all your contacts and conversations in a local SQLite database, making it private and portable by design, owned and controlled by user.
-
-You can view and search your chat history by querying your database. Run the below script to create message views in your database.
-
-```sh
-curl -o- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/message_views.sql | sqlite3 ~/.simplex/simplex_v1_chat.db
-```
-
-Open SQLite Command Line Shell:
-
-```sh
-sqlite3 ~/.simplex/simplex_v1_chat.db
-```
-
-See [Message queries](./message_queries.md) for examples.
-
-> **Please note:** SQLite foreign key constraints are disabled by default, and must be **[enabled separately for each database connection](https://sqlite.org/foreignkeys.html#fk_enable)**. The latter can be achieved by running `PRAGMA foreign_keys = ON;` command on an open database connection. By running data altering queries without enabling foreign keys prior to that, you may risk putting your database in an inconsistent state.
-
-**Convenience queries**
-
-Get all messages from today (`chat_dt` is in UTC):
-
-```sql
-select * from all_messages_plain where date(chat_dt) > date('now', '-1 day') order by chat_dt;
-```
-
-Get overnight messages in the morning:
-
-```sql
-select * from all_messages_plain where chat_dt > datetime('now', '-15 hours') order by chat_dt;
-```
+If you are considering developing with SimpleX platform please get in touch for any advice and support.

+## Help us pay for 3rd party security audit
+
+I will get straight to the point: I ask you to support SimpleX Chat with donations.
+
+We are prioritizing users privacy and security - it would be impossible without your support we were lucky to have so far.
+
+We are planning a 3rd party security audit for the app, and it would hugely help us if some part of this $20,000+ expense could be covered with donations.
+
+Our pledge to our users is that SimpleX protocols are and will remain open, and in public domain, - so anybody can build the future implementations of the clients and the servers. We are building SimpleX platform based on the same principles as email and web, but much more private and secure.
+
+If you are already using SimpleX Chat, or plan to use it in the future when it has more features, please consider making a donation - it will help us to raise more funds. Donating any amount, even the price of the cup of coffee, would make a huge difference for us.
+
+It is possible to donate via:
+
+- [GitHub](https://github.com/sponsors/simplex-chat) - it is commission-free for us.
+- [OpenCollective](https://opencollective.com/simplex-chat) - it charges a commission, and also accepts donations in crypto-currencies.
+- Monero wallet: 8568eeVjaJ1RQ65ZUn9PRQ8ENtqeX9VVhcCYYhnVLxhV4JtBqw42so2VEUDQZNkFfsH5sXCuV7FN8VhRQ21DkNibTZP57Qt
