1. buy 100 (or 200) crystal
2. build 4-8 scouts (map size dependent)
3. build queue: shipyard, crystal, metal, metal
4. build capital ship, whatever you want, i prefer kortul or carrier (repair cloud)
5. explore your starsystem and look for uncolonizables to capture the metal and cristal excavators
6. invade nearby asteroid
7. if you really want to rush, scuttle capital ship factory
8. build 1 weapons lab,
9. research assailants and volcanic/arctic, whatever you encounter first
10 build imperial labs until planet slots are full, continue building imperial labs on your colonized planets/asteroids (dont upgrade slots IMO wasted money/crystal)
11. by now you should have captured some or most of the excavators through the galaxy, if you have money problems, use the black market! always balance your metal/crystal/money
13. stop with your 5th imperial lab, research phase gates, then continue to build imperial labs
14. now you should build phase gates so they can collect antimatter until you finished researching
rest should be clear, continue the way you want to, i havent figuered out what to research after dd2, i guess it's your choice

always have a small fleet of assailliants and your cap ship (of course a migrator if you dont build the evacuator
if you play with pirates, it could get ugly with a very small fleet, i prefer non pirate maps

after 20 minutes you should have your first dark armada research (depends all on found cristal/metal extractors and spawn luck)
additionally you can research the +xx% crystal/metal extraction and trade ports
lots of macro managing btw to capture the excavators, and micro managin to keep them alive, always keep your scouts moving if there are enemy ships in those sectors, you can outrun pretty much ever random spawn, just make some waypoints (across the whole gravity well, because they are suck in changing directions)
i guess i do a lot of things too but i consider them basics, so i may have forgotten some things
