+# HDL Plugin
+
+The main function of the HDL plugin is to provide access to the HTTP-FLV protocol.
+
+## Plugin Address
+
+https://github.com/Monibuca/plugin-hdl
+
+## Plugin Introduction
+```go
+import (
+    _ "m7s.live/plugin/hdl/v4"
+)
+```
+
+## Default Plugin Configuration
+
+```yaml
+hdl:
+  http: # Refer to global configuration for format
+  publish: # Refer to global configuration for format
+  subscribe: # Refer to global configuration for format
+  pull: # Format: https://m7s.live/guide/config.html#%E6%8F%92%E4%BB%B6%E9%85%8D%E7%BD%AE
+```
+
+## Plugin Features
+
+### Pulling HTTP-FLV Streams from M7S
+
+If the live/test stream already exists in M7S, then HTTP-FLV protocol can be used for playback. If the listening port is not configured, then the global HTTP port is used (default 8080).
+
+```bash
+ffplay http://localhost:8080/hdl/live/test.flv
+```
+
+### M7S Pull HTTP-FLV Streams from Remote
+
+The available API is:
+`/hdl/api/pull?target=[HTTP-FLV address]&streamPath=[stream identifier]&save=[whether to save configuration (leave blank if not)]`
+
+### Get a List of All HDL Streams
+
+`/hdl/api/list`
