Tokamak edge plasma with X-point orbit loss and wall-contact is in non-thermal state, and governed by the overlapping multiscale and multi-physics self-organization dynamics. The gyrokinetic particle code XGC1 has been developed to attack such problems on first-principles base. The techniques utilized in XGC1 will be introduced with example physics solutions; that includes, unstructured triangular mesh, particle- continuum technique, fully nonlinear Fokker-Planck collision equation solver, blobby edge turbulence, electromagnetic instabilities, edge transport bifurcation, divertor heat- flux, etc. This talk will be designed to be informative to a broader audience.
