Editing Warhammer 40,000/8th Edition Tactics/Chaos Space Marines (section)

===Getting Started===

Whether you are a fresh recruit to the ways of chaos or a grizzled veteran of the long war returning after a long absence, you will need the most up to date copy of the rules available. 8th edition has been marked by continual change, with unit entries being rewritten weeks (or in the case of the Imperial Guard, mere days) after a codex has been released. Gathered here is an ordered list of all of the books containing rules for this faction and why you might need them

*'''The Most Recent FAQ and Erratas''': For all of the Below. As they're all relevant and have tweaks and FAQ answers that all affect your army. These resources include Chapter Approved, Forgeworld Publications, Warhammer Community Posts, White Dwarf articles etc etc.
*'''Codex Chaos Space Marines, Version 2''': Released in 2019, this books bundles in a-lot of the rules introduced in Vigilus Ablaze, If you have the hard-back it contains the most recent point costs taken from the 2018 Chapter Approved.
*'''Faith & Fury''': Book 2 of the [[Psychic Awakening]] event. It contains additional rules for the Traitor Legions besides the {{W40kKeyword|BLACK LEGION}}.
*'''Imperial Armour - Index: Forces of Chaos''': The index sheets for the majority of Forge-world units you may wish to take.
*'''Vigilus Ablaze''': A campaign book covering the second part of the invasion of the Vigilus System. Quite biased to the Black Legion (due to lore purposes) but also contains additional rules for renegade chapters and the {{W40kKeyword|BLACK LEGION}} as well as specialist detachments for all Chaos Marine forces.
*'''Index: Chaos''': If you want to run a legacy option not found in the codex, such as a character on a bike/daemonic mount.
*'''Shadowspear''': A box set that doubles as both a starting set and a vehicle for new models/units. You can download the rules for free. Mainly used for the Psyker-focused Warlord traits, as now everything in Shadowspear can be found in one of the sources above.
*'''Blackstone Fortress''': Contains a set of super-niche {{W40kKeyword|CHAOS}} key-worded units. Probably going to only be used in Open/Narrative Play
*'''Kill Team: Rogue Trader''': Specifically the Gellar-pox infected mini-codex. Again though probably used only for Open/Narrative play. 

Once you've got all of those, keep in mind that you're going to want to decide on your playstyle next, informed by the units you want to use, and then finally you're going to have to choose a Legion or Renegade Chapter that you're army's a part of. While that might not sound as important, the various options can offer bonuses that either heavily benefit your playstyle, or could even detract from it, so choose carefully.
