+##### Compiling from source
+Prerequisites: Git, [Cargo](https://www.rust-lang.org/install.html),
+  Full C build environment including autotools (for building libsodium)
+
+The checked-out code can be compiled with ``make``.
+The binary could then be found in `target/release/vpncloud`.
+The tests can be run via ``cargo test``.
+
+
+##### Debian / Ubuntu
+Deb packages for each release can be found in the [releases](https://github.com/dswd/vpncloud.rs/releases) section.
