-Welcome to the open-source implementation of
-[SCION](http://www.scion-architecture.net) (Scalability, Control and Isolation
-On next-generation Networks), a future Internet architecture. SCION is the first
-clean-slate Internet architecture designed to provide route control, failure
-isolation, and explicit trust information for end-to-end communication. To find
-out more about the project, please visit our [documentation
-site](https://docs.scion.org/en/latest/).

-## Connecting to the SCION Test Network
+## Installation
 
-Join [SCIONLab](https://www.scionlab.org) if you're interested in playing with
-SCION in an operational global test deployment of SCION. As part of the SCIONLab
-project, we support [pre-built binaries as Debian
-packages](https://docs.scionlab.org/content/install/).
+Installation packages for Debian and derivatives are available for x86-64, arm64, x86-32 and arm.
+These packages can be found in the [latest release](https://github.com/scionproto/scion/releases/latest).
+Packages for in-development versions can be found from the [latest nightly build](https://buildkite.com/scionproto/scion-nightly/builds/latest).
 
-## Building
+Alternatively, "naked" pre-built binaries are available for Linux x86-64 and
+can be downloaded from the [latest release](https://github.com/scionproto/scion/releases/latest) or the
+[latest nightly build](https://buildkite.com/scionproto/scion-nightly/builds/latest).
 
-To find out how to work with SCION, please visit our [documentation
-site](https://docs.scion.org/en/latest/dev/setup.html)
-for instructions on how to install build dependencies, build and run SCION.
+### Build from sources
 
-Pre-built binaries for x86-64 Linux are available from the [latest nightly build](https://buildkite.com/scionproto/scion-nightly/builds/latest).
+SCION can be built with `go build`. To build all binaries needed in a SCION deployment (i.e. excluding the testing and development tools), run
+
+```
+CGO_ENABLED=0 go build -o bin ./router/... ./control/... ./dispatcher/... ./daemon/... ./scion/... ./scion-pki/... ./gateway/...
+```
+
+The default way to build SCION, however, uses Bazel.
+In particular, this allows to run all the tests, linters etc.
+Please visit our [documentation site](https://docs.scion.org/en/latest/dev/setup.html) for instructions on how to set up Bazel and the full development environment.
+
+### Connecting to the SCION Network
