+# `lbry`
+
+`lbry` is a protocol that identifies specific content on the LBRY network. This can be a channel, a stream or a playlist.
+
+## Representation Format
+
+### Human-readable
+
+The human-readable format of the `lbry` protocol is used in the same way as the URLs at [https://lbry.tech/spec](https://spec.lbry.com/#urls), but in this case the scheme is `/lbry/` instead of `lbry://`, so:
+
+#### Stream Claim Name
+
+	/lbry/meet-lbry
+
+#### Channel Claim Name
+
+	/lbry/@lbry
+
+#### Channel Claim Name and Stream Claim Name
+
+	/lbry/@lbry/meet-lbry
+
+#### Claim ID
+
+	/lbry/meet-lbry:7a0aa95c5023c21c098
+	/lbry/meet-lbry:7a
+	/lbry/@lbry:3f/meet-lbry
+
+#### Sequence
+
+	/lbry/meet-lbry*1
+	/lbry/@lbry*1/meet-lbry
+
+#### Amount Order
+
+	/lbry/meet-lbry$2
+	/lbry/meet-lbry$3
+	/lbry/@lbry$2/meet-lbry
+
+### Binary
