+Euclid [![Build Status (Travis)][badge-travis]][build-travis] [![Build Status (Appveyor)][badge-appveyor]][build-appveyor]
 ======
 
 Euclid will be a UI framework for terminal environments, like actual desktop
 terminal emulator or [rot.js][rot-js]. 
 
+Build
+-----
+
+To build the project (just a stub for now), install [SBT][sbt] and then execute
+the following command in your terminal:
+
+```console
+$ sbt compile
+```
+
+Test
+----
+
+To execute the automatic test suite, run the following command in your terminal:
+
+```console
+$ sbt test
+```
+
+Run
+---
+
+To run the manual test projects (just stubs for now) for JVM and Scala.js,
+execute the following commands in your terminal:
+
+```console
+$ sbt 'project euclidJVM' run
+$ sbt 'project euclidJS' run
+```
