+- [x] Proper URL normalization
+- [x] Handle redirects (3X status codes)
+
+## How to run
+
+Spin up a PostgreSQL, check `db/sql/initdb.sql` to create the tables and start the crawler.
+All configuration is done via environment variables.
+
+## Configuration
+
+Bool can be `true`,`false` or `0`,`1`.
+
+```text
+	LogLevel               string // Logging level (debug, info, warn, error)
+	MaxResponseSize        int // Maximum size of response in bytes
+	NumOfWorkers           int // Number of concurrent workers
+	ResponseTimeout        int // Timeout for responses in seconds
+	WorkerBatchSize        int // Batch size for worker processing
+	PanicOnUnexpectedError bool // Panic on unexpected errors when visiting a URL
+	BlacklistPath          string // File that has blacklisted strings of "host:port"
+	DryRun                 bool // If false, don't write to disk
+	PrintWorkerStatus      bool // If false, print logs and not worker status table
+```
+
+Example:
+
+```shell
+LOG_LEVEL=info \
+NUM_OF_WORKERS=10 \
+WORKER_BATCH_SIZE=10 \
+BLACKLIST_PATH="./blacklist.txt" \ # one url per line, can be empty
+MAX_RESPONSE_SIZE=10485760 \
+RESPONSE_TIMEOUT=10 \
+PANIC_ON_UNEXPECTED_ERROR=true \
+PG_DATABASE=test \
+PG_HOST=127.0.0.1 \
+PG_MAX_OPEN_CONNECTIONS=100 \
+PG_PORT=5434 \
+PG_USER=test \
+PG_PASSWORD=test \
+DRY_RUN=false \
+./gemini-grc
+```
+
+## Development
+
+Install linters. Check the versions first.
+```shell
+go install mvdan.cc/gofumpt@v0.7.0
+go install github.com/golangci/golangci-lint/cmd/golangci-lint@v1.63.4
+```
 
 ## TODO
 - [ ] Add snapshot history
 - [ ] Add a web interface
 - [ ] Provide to servers a TLS cert for sites that require it, like Astrobotany
+- [ ] Use pledge/unveil in OpenBSD hosts
 
 ## TODO (lower priority)
 - [ ] Gopher
-- [ ] Scroll gemini://auragem.letz.dev/devlog/20240316.gmi
-- [ ] Spartan
-- [ ] Nex
-- [ ] SuperTXT https://supertxt.net/00-intro.html
+- [ ] More? http://dbohdan.sdf.org/smolnet/
