+## Installation
+
+### pip
+
+```console
+pip install dlhdhr
+```
+
+### docker
+
+``` console
+docker run --rm -p 8000:8000 brettlangdon/dlhdhr:latest
+```
+
+## Running
+
+``` console
+# Start the server
+dlhdhr
+```
+
+## Configuration
+
+All Configuration is done via environment variables.
+
+``` console
+DLHDHR_HOST="0.0.0.0" DLHDHR_PORT="8080" dlhdhr
+
+docker run --rm -e "DLHDHR_PORT=8080" -p 8080:8080 brettlangdon/dlhdhr:latest
+```
+
+### Server
+
+- `DLHDHR_HOST="<ip-address>"`
+  - Which ip address bind to. `dlhdhr` command default is "127.0.0.1", the docker container defaults to "0.0.0.0".
+- `DLHDHR_PORT="<port>"`
+  - Which port the server should bind to. Default is "8000".
+
+### Channel selection
+By default `dlhdhr` will include all channels from DaddyLive, however you can select or exclude specific channels.
+
+- `DLHDHR_CHANNEL_EXCLUDE="<cn>,<cn>,<cn>,...`
+  - Exclude the specified DaddyLive channel numbers.
+- `DLHDHR_CHANNEL_ALLOW="<cn>,<cn>,<cn>,...`
+  - Include only the specified DaddyLive channel numbers.
+
+### EPG
+#### default
+
+By default `dlhdhr` will generate an `xmltv.xml` with only the channel numbers and names.
+
+#### epg.best
+- `DLHDHR_EPG_PROVIDER="epg.best"`
+- `DLHDHR_EPG_BEST_XMLTV_URL="https://epg.best/<filename>.m3u"`
+
+## Endpoints
+
+- `/discover.json`
+- `/lineup_status.json`
+- `/listings.json`
+- `/lineup.json`
+- `/xmltv.xml`
+- `/iptv.m3u`
+- `/channel/{channel_number:int}/playlist.m3u8`
+- `/channel/{channel_number:int}/{segment_path:path}.ts`
+- `/channel/{channel_number:int}`
