+# Technology radar
+
+Knowledge-sharing tool providing a snapshot of the current adoption of tools, techniques, platforms, languages and
+frameworks.
+
+1. [TL;DR](#tldr)
+1. [Further readings](#further-readings)
+   1. [Sources](#sources)
+
+## TL;DR
+
+Imagine a radar.
+
+Divide the radar in multiple concentric _rings_.<br/>
+The rings should represent the confidence of technologies adoption, something like follows (inner to outer):
+
+- Adopt: technologies that one should seriously consider using.
+- Trial: technologies that one could consider ready for use, but not with the level of confidence granted to those in
+  the Adopt ring.
+- Assess: technologies to look at closely, but not necessarily in Trial yet; to consider trying should one think they
+  would be a particularly good fit.
+- Hold: unknown technologies; proceed with caution.
+
+Divide the radar in _quadrants_.<br/>
+Quadrants should represent groups of technologies (e.g.: tools, platforms, languages…).
+
+Each technology insight is represented by a _blip_.<br/>
+Blips can (and in time, should) move between rings as one's recommendation changes.
