EiRRMod posted a basic guide of how to use the Warmap with his initial post releasing it. However, he did miss a few of the finer points such as statistics for the map.
Before I expand on what he detailed, I'll contain his original post here:
So, onto the warmap details!
The warmap is made of sectors to fight over.
Firstly, deploy yourself to a sector (spawn point) notated by a large circle with your factions icon.
Next, because you will probably be behind the lines, set yourself to Defend, or Support action.
These actions will boost the defence/support value of the sector you are in.
After your first battle is completed (as normal, in COH), you will gain an Action point.
These action points allow you to move your company, and deselect doctrine selections.
Move to the front lines, and attack a neutral or enemy territory and take it over!
Warmap numbers at the bottom of the warmap screen
CW-US-WM-PE
PP is no longer gained on a per-person basis.
It is gained after a battle is completed, and you put points into the doctrine selection at the battle results screen.
PP total = Faction points / 100.
If you choose 'Strategy' instead of 'Doctrine' at this point, your next battles warmap affect, will be boosted by 20 per point invested, regardless of victory margin. This may be the path to take if you are attempting to ensure the downfall (or defence) of a falling sector.
The advantages screen has changed too.
You no longer select your Resource bonuses.
Instead, you gain an amount equal to what you hold on the warmap.
As an additional bonus, if you are located in a sector with a resource bonus, you will get resources equal to what the OPPONENT would get -1 sector.
There are many more things to come, and this guide is but a scratch on the surface
Gaining SPFirst off, a note on how SP works. SP is no longer brought with PP. To gain access to SP, you must either be in a supply depot (One of your faction's spawns) or within range of it. For every sector that you are away from a supply depot, you will have 10 less SP to work with. The supply depot itself gives 40 SP so you can be a maximum of 4 tiles away before SP is totally cut off.
There is always a minimum of 5SP available at all times.
There will be warmap cards later on which will provide the ability to set up temporary supply depots and the such. For now however, it all hangs on your spawn points.
Offence notesTo attack a sector costs your current sector 20 support points. However, if any other friendly sectors are connected to the territory that you are attacking, they will provide benefits. This will in turn, cost the assisting sector(s) 10 points.
Each assisting sector provides +20 to your offence or defence. It should also be noted that each strategy point that you take at the end of a match will give +20 points into your offence and defence per strategy point. This will only affect your NEXT battle. If I take 6 points into strategy, that means that even if I suffer a defeat, my next match will have me put in at least 120 points of offence or defence. Victory on the other hand, will make for a very sweet bonus.
Defence notesDefending a sector costs 10 support points each time.
Defence ModifierThe defence modifier can be reduced, and raised in several ways:
Firstly, an overwhelming attack action will reduce the defence modifier by 2%.
A support action, will restore 2%.
Any action that reduces the support of a sector to 0, will incur a -1% defence modifier per 10 support used.
Doctrine notesWith the implementation of the warmap, you are now required to have 1 action point to remove any doctrine selections. 1 Point per selection.
Unique SectorsCurrently, Airfield and Factory sectors do not provide any bonuses for the moment, but will have warmap wide and sector specific effects upon implementation.
Individual Company ProgressAs it stands, individual company progress is limited to what doctrines you choose. However, companies still gain experience for their warmap rank at a rate of 5 exp per game and +1 exp for each victory margin (6 for a narrow victory, 7 for a standard victory and 8 for an overwhelming victory).
As of yet, warmap rank does nothing, but will have an impact on the warmap in due time.

This list is not exhaustive, and will be updated over time as I find out more details from experience, EiRRMod himself, or community contributions.
Feel free to mention anything I haven't and I'll update the main post.
