+AlekSIS — All-libre extensible kit for school information systems
+=================================================================
+
+Warning
+-------
+
+**This is an alpha version of AlekSIS, the free school information system.
+The AlekSIS team is looking for schools who want to help shape the 2.0
+final release and supports interested schools in operating AlekSIS.**
+
+What AlekSIS is
+----------------
+
+`AlekSIS`_ is a web-based school information system (SIS) which can be used to
+manage and/or publish organisational subjects of educational institutions.
+
+Formerly two separate projects (BiscuIT and SchoolApps), developed by
+`Teckids e.V.`_ and a team of students at `Katharineum zu Lübeck`_, they
+were merged into the AlekSIS project in 2020.
+
+AlekSIS is a platform based on Django, that provides central funstions
+and data structures that can be used by apps that are developed and provided
+seperately. The AlekSIS team also maintains a set of official apps which
+make AlekSIS a fully-featured software solutions for the information
+management needs of schools.
+
+By design, the platform can be used by schools to write their own apps for
+specific needs they face, also in coding classes. Students are empowered to
+create real-world applications that bring direct value to their environment.
+
+AlekSIS is part of the `schul-frei`_ project as a component in sustainable
+educational networks.
