+## Configuration
+
+Copy [`example_config.json`](https://github.com/chihaya/chihaya/blob/master/example_config.json)
+to your choice of location, and update the values as required.
+The available keys and their default values are as follows:
+
+- `private_enabled: false` – if this is a private tracker
+- `freeleech_enabled: false` – for private trackers, whether download stats should be counted
+- `purge_inactive_torrents: true` – if torrents should be forgotten after some time
+- `announce: "30m"` – the announce "interval" value sent to clients
+- `min_announce: "15m"` – the announce "min_interval" value sent to clients
+- `default_num_want: 50` – the default number of peers to return if the client has not specified
+- `torrent_map_shards: 1` – number of torrent maps to use (leave this at 1 in general)
+- `allow_ip_spoofing: true` – if peers are allowed to set their own IP, this must be enabled for dual-stack IP support
+- `dual_stacked_peers: true` – if peers may have both an IPv4 and IPv6 address, otherwise only one IP per peer will be used
+- `real_ip_header: ""` – optionally an HTTP header where the upstream IP is stored, for example `X-Forwarded-For` or `X-Real-IP`
+- `respect_af: false` – if responses should only include peers of the same address family as the announcing peer
+- `client_whitelist_enabled: false` – if peer IDs should be matched against the whitelist
+- `client_whitelist: []` – list of peer ID prefixes to allow
+- `http_listen_addr: ":6881"` – listen address for the HTTP server
+- `http_request_timeout: "10s"`
+- `http_read_timeout: "10s"`
+- `http_write_timeout: "10s"`
+- `http_listen_limit: 0`
+- `driver: "noop"`
+- `stats_buffer_size: 0`
+- `include_mem_stats: true`
+- `verbose_mem_stats: false`
+- `mem_stats_interval: "5s"`

 ## Testing
 
 Chihaya has end-to-end test coverage for announces in addition to unit tests for
