+# Owl Positioning System
+
+**OwlPS** (_Owl Positioning System_) is a positioning (localization) system
+based on the IEEE 802.11 radio network (Wi-Fi), targeting mainly indoor
+environments. It uses an infrastructure-centred architecture, which means the
+infrastructure does the measurements and computes the mobile terminals'
+positions, rather than the terminals computing their own positions (as it is
+the case for instance with the GPS).
+
+OwlPS implements various positioning techniques and algorithms based on the
+radio signal strength. It features a self-calibration (or autocalibration)
+mechanism that avoids the time-consuming manual fingerprinting phase and allows
+considering dynamic changes of the environment (human, climatic, etc.) when
+computing the location of mobile terminals.
+
+**This presentation is an excerpt of `doc/owlps.t2t`. Please refer to this file
+for a more in-depth introduction to OwlPS.**
+
+## News
+
+OwlPS is not currently actively maintained, as I'm not working on indoor
+positioning at the moment, but I'll happily consider any contribution (or
+job offer).
+
+The `CHANGELOG` file lists the changes that occurred in OwlPS, version by
+version, since its early stages.
+
+## Contribute
+
+If you would like to contribute to OwlPS, you can:
+
+ * use it, test it, and report suggestions and bugs on the forge:
+
+
+ * get the latest development code, add functionalities and send me pull
+ requests by email or on the forge:
+
+If you're looking for ideas, the `TODO.t2t` file could be a good start.
+
+## Installation
+
+For a guide to installing OwlPS, please consult `INSTALL.t2t`.
+
+## License
+
+OwlPS is free software, released under the terms of the CeCILL license (GNU
+GPL-compatible). For more detail, please consult `COPYRIGHT.t2t`.
+
+## Note on the t2t file extension
+
+Most of the documentation in this repository is provided as text files in the
+**txt2tags** format (`*.t2t` files). You can convert them to various formats
+(HTML, man pages, etc.) using the [txt2tags](http://txt2tags.org/) utility; if
+you mind the markup tags, you can even strip them using the `txt` output.
