+# GRPC REPL
+
+This is a general-purpose read-eval-print loop tool for interacting with GRPC services for
+debugging and testing in an ad-hoc manner.
+
+Notable features includes:
+* Supports RPC services defined across many `.proto` files by using a `FileDescriptorSet`
+as the basis for messages and methods.
+* Interactive tab-completion / suggestion support for message names, methods,
+and **message contents**.
+* Supports self-signed or private-CA SSL certificates.
+
+## Quickstart
+
+Compile your `.proto` files with `protoc` the way you normally do, but with a couple of
+extra flags: `--descriptor_set_out=my_protos.pb  --include_imports --include_source_info` to produce
+a self-contained `FileDescriptorSet`.
+
+Download and unpack the repl tool:
+
+```sh
+unzip grpc-repl-0.1.zip
+./grpc-repl-0.1/bin/grpc-repl \
+    -d /path/to/my_protos.pb \
+    -t https://my.server
+```
+
+![Demo Screencast](demo.gif)
+
+## Current Status
+
+Right now, this tool is pretty basic, intended mainly for creating ad-hoc queries or helping you 
+create example payloads for documentation.  The output of the help command is displayed here, which
+should give you an overview of what's currently possible.
+
+```
+edit
+    | Edit a message.
+    | 
+    | Usage:
+    |   * edit - List all editable messages
+    |   * edit <variable> - Update an existing message
+    |   * edit <variable> <message type> - Create / replace the named message
+
+header
+    | Set a header.
+    | 
+    | Usage:
+    |   * header - List all currently-set headers
+    |   * header <header> - Show the current value of the header
+    |   * header <header> "new value" - Set the header
+    | 
+    | If the header name ends with "-bin", the value will be
+    | interpreted as a base64-encoded value.
+
+help
+    | Display this message
+
+messages
+    | Describe messages types.
+    | 
+    | TODO: Display the SourceInfo in the descriptor set
+    | 
+    | Usage:
+    |   * messages - To print all message names
+    |   * messages mdlbx.Stat - To print message schema
+
+print
+    | Print a variable.
+    | 
+    | Usage:
+    |   * print - List all messages
+    |   * print <variable> - Print an existing message
+
+quit
+    | Exit the tool
+
+rpc
+    | Execute an RPC call.
+    | 
+    | If the RPC is a client-streaming message, the outgoing stream will be completed
+    | when you type ^D.  The call will be cancelled on a ^C.
+    | 
+    | Usage:
+    |   * rpc - List all RPC methods
+    |   * rpc <method> - Call the method using an interactive editor
+    |   * rpc <method> <variable> - Call the method using the named variable
+    |   * rpc <method> <variable> <variable> .... - Call a client-streaming message
