-1. Demo							*channel-demo*
+1. Overview						*job-channel-overview*
+
+There are four main types of jobs:
+1. A deamon, serving several Vim instances.
+   Vim connects to it with a socket.
+2. One job working with one Vim instance, asynchronously.
+   Uses a socket or pipes.
+3. A job performing some work for a short time, asynchronously.
+   Uses a socket or pipes.
+4. Running a filter, synchronously.
+   Uses pipes.
+
+For when using sockets See |job-start|, |job-may-start| and |channel-open|.
+For 2 and 3, one or more jobs using pipes, see |job-start|.
+For 4 use the ":{range}!cmd" command, see |filter|.
+
+Over the socket and pipes these protocols are available:
+RAW	nothing known, Vim cannot tell where a message ends
+NL	every message ends in a NL (newline) character
+JSON	JSON encoding |json_encode()|
+JS	JavaScript style JSON-like encoding |js_encode()|
+
+Common combination are:
+- Using a job connected through pipes in NL mode.  E.g., to run a style
+  checker and receive errors and warnings.
+- Using a deamon, connecting over a socket in JSON mode.  E.g. to lookup
+  crosss-refrences in a database.

 You can now send a message to the server: >
-	echo ch_sendexpr(handle, 'hello!')
+	echo ch_sendexpr(channel, 'hello!')
 
 The message is received in T1 and a response is sent back to Vim.
