 ## Status
 
-Milestone 2 is reached:
+Milestone 3 is reached and with it Husk has aquired a set of new features:
 
-Husk can encrypt passing mails for simple cases, meaning:
+- Online sources (keyservers, WKD, DANE) are now queried for missing
+  certificates.
+- Introducers are now available: certificates are only used if they are
+  certified by an introducer and match its list of configured domains.
+- Locals are available: These are certificates hand picked and added 
+  by the administrator.
 
-- for all recipients of an email, a valid certificate is locally available.
+## Documentation
-- if that is not the case, Husk will not modify the email.
-- Husk will not query keyservers (or other sources) for certificates - this is part of milestone 3.
 
-Please be patient.
+The documentation (with install instructions) can be found [here](https:://www.husk-project.org/documentation).
 
-## Build
+## Website
-
-Make sure that you have a toolchain for Rust installed. 
-
-Building:
-```
-$ git clone https://gitlab.com/husk-project/husk-milter.git
-$ cd husk-milter
-$ cargo build --release
-```
-
-This creates the binary `./target/release/husk`.
-
-## Installation
-
-To use with `postfix`:
-
-- configure husk, there is an example configuration file in `./config/config.toml`.
-
-    ```
-    #
-    # Husk config file
-    #
-    connection = "localhost:3000"
-
-    logfile_config = "./config/log4rs.yml"
-    ```
-    
-    Husk uses `log4rs` for logging. There is an example configuration in the
-    `./config` subdirectory as well.
-
-- Configure `postfix`:
-    
-    Make sure that the `main.cf` configuration file contains a line like:
-    ```
-    smtpd_milters = inet:localhost:3000
-    ```
-    `smtpd_milters` is used to register milters with postfix, there might be 
-    more than one. The string `inet:localhost:3000` corresponds to the 
-    `connection` setting in `config.toml`.
-
-    You can add the line 
-
-    ```
-    non_smtpd_milters = $smtpd_milters
-    ```
-
-    directly after the line containing `smtpd_milters`, so that local calls to `sendmail` will also invoke `Husk`.
-
-- Start the milter:
-    
-    Assuming you are in the root directory of the project:
-
-    ```
-    $ ./target/release/husk ./config/config.toml
-    ```
-
-- Restart postfix:
-
-    In case you are using systemd:
-    ```
-    # systemctl restart postfix.service
-    ```
-
-- Send a mail and check the logfile.
