-Elpher is available from the MELPA package repository. If you have
+@section Installing from ELPA or MELPA
+
+Elpher is available on the non-GNU ELPA package archive. If you are
+using Emacs 28 or later, this archive should be available on your system
+by default. For Emacs 27, you'll need to follow the instructions at
+@url{https://elpa.nongnu.org} to make the archive accessible.
+
+Alternatively, Elpher is available from the MELPA package archive. If you have
never installed packages from this repository before, you'll need
to follow the instructions at @url{https://melpa.org/#/getting-started}.
-@noindent To install Elpher, enter the following:
+Once one of these package archives is installed, enter the following to
+install Elpher:
@example
@kbd{M-x package-install @key{RET} elpher @key{RET}}
@kbd{M-x package-delete @key{RET} elpher @key{RET}}.
@end example
+@section Installing by hand
+
It is also possible to install Elpher directly by downloading the file
@file{elpher.el} from @url{gopher://thelambdalab.xyz/1/projects/elpher}
(you'll need to download the ``source archive'' and extract it), adding

@chapter About pages
Like other browsers, elpher makes certain internally-generated pages
This means that these pages can be bookmarked and, more usefully,
added to a local file to be rendered as a user-defined start page.

+@chapter ANSI support
+
+Depending on which parts of the gopher/gemini universe you frequent,
+you may occasionally stumble on sites which use ANSI escape codes to
+either produce specific characters or to colour text.
+
+By default, elpher uses Emacs' built-in ANSI rendering library,
+@samp{ansi-color}, to process ANSI codes. This robustly interprets
+the escape codes but only supports 8 colours. Any colours unsupported
+by the library are simply stripped, leaving uncoloured text in the
+majority of cases.
+
+To drastically improve the number of colours produced, install the
+@samp{xterm-color} package from MELPA. This package will be automatically
+used by elpher if it is available, and supports 256 colours.
+This should be sufficient to properly render many ANSI colour
+gopher holes and gemini capsules quite nicely.
+
+In case you prefer to completely strip out the ANSI escape codes entirely
+by customizing the @code{elpher-filter-ansi-from-text} variable.

@chapter News
This chapter documents the major changes introduced by Elpher releases.
+@section v3.3.0
+
+This version includes lots of bug fixes, as well as a couple of new
+features.
+
+@subsection Local gophermaps
+
+Local gophermaps can now be displayed using @samp{file:}. To render
+correctly, they must have the suffix @samp{.gopher} or @samp{.gophermap}.
+
+@subsection IRI support
+
+Internationalized Resource Identifiers (IRI) are an extension of URLs
+(or, more accurately, URIs) to support a larger set of characters beyond
+those in the US-ASCII character set. They map directly onto URIs for
+backwards compatibility, but look like gibberish if not properly
+decoded. When displaying URLs, Elpher now automatically decodes any IRI
+characters and displays the decoded IRI. (For security reasons, the
+@code{elpher-info-current} command (@kbd{I}) always displays both the
+decoded IRI and the URI when they differ.)
+
@section v3.2.0
This version introduces several minor changes which, together, make it
Special elpher pages such as the welcome page (previously ``start''
page), the bookmarks page, the browsing history stack and list of
-visited pages are now addressible via @samp{about:} URLs. For instance,
+visited pages are now addressable via @samp{about:} URLs. For instance,
the standard welcome page has the address @samp{about:welcome}.
@subsection Local files
Gemini document headers are now navigable via imenu.
For details, @xref{Imenu, , , emacs, The Emacs Editor}.
