 ## jrpc
 
+it is a jsonrpc2-like framework, allowing for json rpc over multiple different protocols.
 
-this is a weird amalgamation of go-chi and the rpc package in go-ethereum
+it also has interfaces similar to chi for routing, middleware, etc.
 
+different transports are defined, such as http, websocket, or ipc, (net.Conn), stdio (io.Reader/io.Writer)
+
+it also supports subscriptions, such as those in the original ethereum json-rpc specification
+
+it is based off of the http router chi, and the go-ethereum, sourcegraph, and gopls json-rpc packages.
