Start here

The main README is the tour: what the engine is, what it can do, and why it's built the way it is. This manual holds the guides that go deeper:

ChapterAnswers
Getting startedHow do I get from zero to a deployed site -- locally, on a VPS, on Cloudron, on Pages?
Writing, The archive, Running itHow do I run it day to day -- writing, deploying, cron, backup, troubleshooting?
ArchitectureHow does it work inside -- content model, build pipeline, deploy, client side, security?
DecisionsWhy is it built this way -- the trade-offs, each with its admitted cost?
ImportingHow do I bring an old blog in -- per-source guides, what gets kept, how to undo?
SkinningHow do I make it look like something else -- without forking the engine?
LocalizationHow do I translate the engine into my language?
ReleasingWhat has to be true before a tag, and what happens after it?

Where to start, by situation

SituationRead
Evaluating the enginemain README → the screenshots → Why this exists → What it does
Setting up a siteGetting started, top to bottom
Writing and publishing postsWriting → Writing and publishing
Dressing the site differentlySkinning -- try ./style.sh first; a skin is the expensive answer
Moving content in from elsewhereImporting, then ./import.sh
Taking content out, or moving the whole siteThe archive → Taking your content elsewhere, then ./blog.sh export
Checking that the archive itself is soundThe archive → Checking the archive, then ./blog.sh check
Something failedRunning it → Troubleshooting
Understanding the internalsArchitecture, then the source -- every lib/ file opens with a design comment
Translating the engineLocalization -- a partial locale is useful from day one
Writing an importerArchitecture → Importing for the adapter contract, → Field reference for the schema to produce
Questioning a design choiceDecisions first -- it may already argue both sides
