+= sshj - SSHv2 library for Java
+Jeroen van Erp
+:sshj_groupid: com.hierynomus
+:sshj_version: 0.11.0
+:source-highlighter: pygments
+
+image::https://travis-ci.org/hierynomus/sshj.svg?branch=master[]
+
+To get started, have a look at one of the examples. Hopefully you will find the API pleasant to work with :)
+
+== Getting SSHJ
+
+To get SSHJ, you have two options:
+
+. Add a dependency to SSHJ to your project.
+. Build SSHJ yourself.
+
+And, if you want, you can also run the SSHJ examples.
+
+Binary releases of SSHJ are not provided here, but you can download it http://search.maven.org/#artifactdetails%7C{sshj_groupid}%7Csshj%7C{sshj_version}%7Cjar[straight from the Maven Central repository] if you want to.
+
+== Depending on SSHJ
+If you're building your project using Maven, you can add the following dependency to the `pom.xml`:
+
+[source,xml,subs="verbatim,attributes"]
+----
+<dependency>
+  <groupId>{sshj_groupid}</groupId>
+  <artifactId>sshj</artifactId>
+  <version>{sshj_version}</version>
+</dependency>
+----
+
+If your project is built using another build tool that uses the Maven Central repository, translate this dependency into the format used by your build tool.
+
+== Building SSHJ
+. Clone the Overthere repository.
+. Ensure you have Java6 installed with the http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html[Unlimited strength Java Cryptography Extensions (JCE)].
+. Run the command `./gradlew clean build`.
+
+== Running the examples
+In the `examples` directory, there is a separate Maven project that shows how the library can be used in some sample cases. If you want to run them, follow these guidelines:
+
+. Install http://maven.apache.org/[Maven 2.2.1] or up.
+. Clone the Overthere repository.
+. Go into the `examples` directory and run the command `mvn eclipse:eclipse`.
+. Import the `examples` project into Eclipse.
+. Change the login details in the example classes (address, username and password) and run them!
+
+== Features of the library include:
+
+* reading known_hosts files for host key verification
+* publickey, password and keyboard-interactive authentication
+* command, subsystem and shell channels
+* local and remote port forwarding
+* scp + complete sftp version 0-3 implementation
+
+== Supported algorithms
+Implementations / adapters for the following algorithms are included:
+
+ciphers::
+  `aes{128,192,256}-{cbc,ctr}`, `blowfish-cbc`, `3des-cbc`
+
+key exchange::
+  `diffie-hellman-group1-sha1`, `diffie-hellman-group14-sha1`
+
+signatures::
+  `ssh-rsa`, `ssh-dss`
+
+mac::
+  `hmac-md5`, `hmac-md5-96`, `hmac-sha1`, `hmac-sha1-96`, `hmac-sha2-256`, `hmac-sha2-512`
+
+compression::
+  `zlib` and `zlib@openssh.com` (delayed zlib)
+
+private key files::
+   `pkcs8` encoded (what openssh uses)
+
+If you need something that is not included, it shouldn't be too hard to add (do contribute it!)
+
+
+== Dependencies
+Java 6+. http://www.slf4j.org/download.html[slf4j] is required. http://www.bouncycastle.org/java.html[bouncycastle] is highly recommended and required for using some of the crypto algorithms. http://www.jcraft.com/jzlib/[jzlib] is required for using zlib compression.

+SSHJ 0.11.0 (No date set yet)::
+* New maven coordinates `com.hierynomus:sshj:0.11.0` as https://github.com/hierynomus[@hierynomus] took over as maintainer of SSHJ
+* Migrated build system to Gradle 2.2.1
