As a follow-up to the question I recently asked on PyQGIS, can someone please point me to a document, webpage or thread that provides me with step-by-step instructions as to how to install an external QGIS plugin?
I've read through the manual's "Loading an external QGIS plugin" section and I have not succeeded in decrypting either of the following two threads: How to install Openlayers plugin on Qgis 1.8? or How to install QGIS 1.8 plugin Georeferencer?
I tried to add the Sextante repository https://github.com/qgis/Quantum-GIS.git in the plugin manager, but it remains empty under the plugins tab. I'm obviously missing some fundamental piece here. I also cannot find my plugins directory (C:\Program Files\Quantum GIS Lisboa... ????).
Any help is much appreciated,
