+---
+
+# Marmot CLI
+
+## Usage
+
+You can run Marmot like this:
+
+```bash
+marmot --config /path/to/config.toml -cluster-addr localhost:4221 -cluster-peers 'nats://localhost:4222/'
+```
+
+You can clean up Marmot triggers and changelogs like this:
+
+```bash
+marmot --config /path/to/config.toml --cleanup
+```
+
+You can take snapshot and upload like this:
+
+```bash
+marmot --config /path/to/config.toml --save-snapshot
+```
+
+Minimal Config
+
+```toml
+seq_map_path="/tmp/marmot-1-sm.cbor"

+## Sample Config File
+
+```toml 
+# Path to target SQLite database
+db_path="/tmp/marmot.db"
+
+# ID to uniquely identify your nodes in your cluster
+# It's recommended to always configure this
+# node_id=1
+
+# Path to persist the saved sequence map on disk for warm reboot
+# If this file is missing Marmot has to download snapshot
+# and replay all logs in order to restore database
+# seq_map_path="/tmp/seq-map.cbor"
+
+# Replication enabled/disabled (default: true)
+# This will allow process to consume incoming changes from NATS
+# replicate = true
+
+# Publishing enabled/disabled (default: true)
+# This will allow process to control publishing of local DB changes to NATS
+# publish = true
+
+# Number of maximum rows to process per change allows configuring the maximum number of rows Marmot
+# will process (scan/load in memory) before publishing to NATS (default: 512)
+# scan_max_changes = 512
+
+# Cleanup interval in milliseconds used to clean up published rows. This is done in order to reduce write
+# load on the system (default: 5000)
+# cleanup_interval = 5000
+
+# Sleep timeout in milliseconds, useful for serverless scenarios. If there is no activity within given timelimit,
+# a snapshot will be performed, and process will exit. Value of 0 means it's disabled (default: 0).
+# sleep_timeout = 15000
+
+# Polling interval in milliseconds, that will explicitly check DB for change logs. This should not be required,
+# it's only useful for broken or buggy file system watchers. Value of 0 means it's disabled (default: 0)
+# polling_interval = 0
+
+# Snapshots are used to limit log size and have a database snapshot backedup on your
+# configured blob storage (NATS for now). This helps speedier recovery or cold boot
+# nodes to come up. A Snapshot is taken every log entries are close to max_entries
+# configured in replication_log section. It's recommended to use a large value
+# for maximum entries in replication log, because SQLite can do 1000s of TPS
+# replaying a couple thousands of entries should be really quick.
+[snapshot]
+# Disabling snapshot disables both restore and save
+enabled=true
+# Storage for snapshot can be "nats" | "webdav" | "s3" (default "nats")
+store="nats"
+# Interval sets perodic interval in milliseconds after which an automatic snapshot should be saved
+# If there was a snapshot saved within interval range due to other log threshold triggers, then
+# new snapshot won't be saved (since it's within time range), a value of 0 means it's disabled.

+# Directory path within bucket where snapshot is saved and restore from
