+# NAME
+
+aerc - the world's best email client
+
+# INTRODUCTION
+
+Welcome to aerc! This tutorial will guide you through your first steps in using
+the client. This tutorial is a man page - you can read it again later with
+*:help tutorial* from aerc, or *man aerc-tutorial* from your terminal.
+
+First, let's introduce some basic keybindings. For convention, we'll use *<C-p>*
+to represent Ctrl+p, which matches the convention used for writing keybindings
+for aerc.
+
+*C-n*
+	Cycles to the next tab
+
+*C-p*
+	Cycles to the previous tab
+
+Try using these now to switch between your message list and the tutorial. In
+your message list, we use vim-style keys to get around.
+
+*k*, *j*
+	Scrolls up and down between messages
+
+*<C-u>*, *<C-d>*
+	Scrolls half a page up or down
+
+*g*, *G*
+	Selects the first or last message, respectively
+
+*K*, *J*
+	Switches between folders in the sidebar
+
+*<Enter>*
+	Opens the selected message
+
+# THE MESSAGE VIEWER
+
+Press *<Enter>* to open a message. By default, the message viewer will display
+your message using *less*(1). This should also have familiar, vim-like
+keybindings for scrolling around in your message.
+
+Multipart messages (messages with attachments, or messages with several
+alternative formats) show a part selector on the bottom of the message viewer.
+
+*<C-k>*, *<C-j>*
+	Cycle between parts of a multipart message
+
+*q*
+	Close the message viewer
+
+# COMPOSING MESSAGES
+
+Return to the message list by pressing *q* to dismiss the message viewer. Once
+there, let's compose a message.
+
+*C*
+	Compose a new message
+
+*rr*
+	Reply to a message
+
+*rq*
+	Reply to a message, and pre-fill the editor with a quoted version of the
+	message being replied to
+
+*Rr*
+	Reply-all to a message
+
+*Rq*
+	Reply-all to a message, and pre-fill the editor with a quoted version of the
+	message being replied to
+
+For now, let's use *C* to compose a new message. The message composer will
+appear. You should see To, From, and Subject lines, as well as your *$EDITOR*.
+You can use *<Tab>* or *<C-j>* and *<C-k>* to cycle between these fields (tab
+won't cycle between fields once you enter the editor, but *<C-j>* and *<C-k>*
+will).
+
+Let's send an email to yourself. Note that the To and From headers only accept
+RFC 5322 addresses, e.g. *John Doe <john@example.org>*, or simply
+*<john@example.org>*. Go ahead and fill out an email (to yourself, perhaps?),
+then close the editor.
+
+The message review screen is shown next. You have a chance now to revise the
+email before it's sent. Press *y* to send the email if it looks good.
+
+# USING THE TERMINAL
+
+aerc comes with an embedded terminal, which you've already used to view and edit
+emails. We can also use this for other purposes, such as referencing a git
+repository while reviewing a patch. From the message list, we can use the
+following keybindings to open a terminal:
+
+*<C-t>*
+	Opens a new terminal tab, running your shell
+
+*$*, *!*
+	Prompts for a command to run, then opens a new terminal tab running that
+	command
+
+*|*
+	Prompts for a command to run, then pipes the selected email into that
+	command and displays the result on a new terminal tab
+
+Try pressing *$* and entering "top". You can also use the *:cd* command to
+change aerc's working directory, and the directory in which new terminals run.
+Use *:pwd* to see it again if you're not sure where you are.
+
+# ADDITIONAL NOTES
+
+## COMMANDS
+
+Every keybinding is ultimately bound to an aerc command. You can also summon the
+command line by pressing ':', then entering one of these commands. See *aerc*(1)
+or *:help* for a full list of commands.
+
+## MESSAGE FILTERS
+
+When displaying messages in the message viewer, aerc will pipe them through a
+_message filter_ first. This allows you to decode messages in non-plaintext
+formats, add syntax highlighting, etc. aerc ships with a few default filters:
+
+- Emails which begin with "[PATCH" will be piped into a filter for rendering
+  git-format-patch and hg export emails.
+- text/html is rendered with w3m in a network sandbox
+- text/\* is rendered with a simple filter for coloring quoted text
+
+## CUSTOMIZING AERC
+
+Aerc is highly customizable. Review *aerc-config*(5) (or use *:help config*) to
+learn more about how to add custom keybindings, install new message filters,
+change its appearance and behavior, and so on.
