The Codex is an archive to keep track of everything that's going on in the galaxy. You post your initial Application and starting units then each single month you update your faction's strength. You will initially post your monthly expenditure in the IC to allow all to see, then update your entry here to reflect those expenditures/construction/etc.
Please update this every month, it lets me know how much is being produced and what was spent. If something is posted in here, remember, it effectively doesn't exist. So keep your Codex entry updated.
This is just for your initial application, and subsequent growth. If you aren't part of our RP, please don't post here. One post per RPer, if you please, though two are permissible if you really think you'll beat the character limit. If you are going to take two posts, ensure they are one after another, not separated.
