+# Musenalm
+
+Bibliographie deutscher Almanache des 18. und 19. Jahrhunderts. Runs as a PocketBase-based web app with SQLite storage.
+
+## Commands
+
+Local build (dev assets + sqlite tags used in this repo):
+```bash
+./scripts/build.sh
+```
+
+Manual build equivalent:
+```bash
+go build -tags=dev,fts5,sqlite_icu -o ./tmp/musenalm .
+```
+
+Run (as used in the Docker image):
+```bash
+./scripts/run.sh
+```
+
+Docker image build:
+```bash
+./scripts/docker.sh
+```
+
+Reset local data directory:
+```bash
+./scripts/reset.sh
+```
+
+Docker Compose (prod/stage):
+```bash
+docker compose up --build
+docker compose -f stage.docker-compose.yml up --build
+```
+
+## Build prerequisites
+
+- Go 1.24 (see `go.mod`, also used in `Dockerfile`).
+- SQLite build tags used in this repo:
+  - Local/dev build: `dev,fts5,sqlite_icu` (see `scripts/build.sh`).
+  - Docker build: `sqlite_fts5,sqlite_json,sqlite_foreign_keys,sqlite_vtable` (see `Dockerfile`).
+- The `dev` build tag serves templates/assets from disk (no embedding). Without it, assets are embedded into the binary.
+
+## Configuration
+
+Config files are loaded in this order, later values override earlier ones:
+1) `config.dev.json` (dev defaults)
+2) `config.json` (runtime overrides)
+3) Environment variables with prefix `MUSENALM_`
+
+### Options
+
+`debug` (bool)  
+Enables PocketBase dev mode and, unless `disable_watchers` is true, turns on template watchers.
+
+`allow_test_login` (bool)  
+Creates/keeps a test superuser account (`demo@example.com` / `password`). When false, the test account is removed if present.
+
+`disable_watchers` (bool)  
+Disables template watchers even if `debug` is true.
+
+Environment variable equivalents:
+- `MUSENALM_DEBUG`
+- `MUSENALM_ALLOW_TEST_LOGIN`
+- `MUSENALM_DISABLE_WATCHERS`
+
+## Hosting
+
+### Docker (recommended)
+
+`docker-compose.yml` runs the app on port 8090 and persists data in `/app/data/pb_data` via an external volume.
+
+Prereqs:
+```bash
+docker volume create musenalm
+docker network create caddynet
+```
+
+Start:
+```bash
+docker compose up --build
+```
+
+Stage uses `stage.docker-compose.yml` and a separate external volume `musenalmstage`.
+
+### Bare binary
+
+Build the binary, then run it with a data directory:
+```bash
+./tmp/musenalm serve --http=0.0.0.0:8090 --dir=/path/to/pb_data
+```
