+# PROTOCOLS
+curl supports numerous protocols, or put in URL terms: schemes. Your
+particular build may not support them all.
+## DICT
+Lets you lookup words using online dictionaries.
+## FILE
+Read or write local files. curl does not support accessing file:// URL
+remotely, but when running on Microsoft Windows using the native UNC approach
+works. Only absolute paths.
+## FTP(S)
+curl supports the File Transfer Protocol with a lot of tweaks and levers. With
+or without using TLS.
+## GOPHER(S)
+Retrieve files.
+## HTTP(S)
+curl supports HTTP with numerous options and variations. It can speak HTTP
+version 0.9, 1.0, 1.1, 2 and 3 depending on build options and the correct
+command line options.
+## IMAP(S)
+Using the mail reading protocol, curl can download emails for you. With or
+without using TLS.
+## LDAP(S)
+curl can do directory lookups for you, with or without TLS.
+## MQTT
+curl supports MQTT version 3. Downloading over MQTT equals subscribing to a
+topic while uploading/posting equals publishing on a topic. MQTT over TLS is not
+supported (yet).
+## POP3(S)
+Downloading from a pop3 server means getting an email. With or without using
+TLS.
+## RTMP(S)
+The **Realtime Messaging Protocol** is primarily used to serve streaming media
+and curl can download it.
+## RTSP
+curl supports RTSP 1.0 downloads.
+## SCP
+curl supports SSH version 2 scp transfers.
+## SFTP
+curl supports SFTP (draft 5) done over SSH version 2.
+## SMB(S)
+curl supports SMB version 1 for upload and download.
+## SMTP(S)
+Uploading contents to an SMTP server means sending an email. With or without
+TLS.
+## TELNET
+Fetching a telnet URL starts an interactive session where it sends what it
+reads on stdin and outputs what the server sends it.
+## TFTP
+curl can do TFTP downloads and uploads.
+## WS(S)
+WebSocket done over HTTP/1. WSS implies that it works over HTTPS.
