Elpher aims to provide a full-featured gopher client for GNU Emacs.
It supports:
-- simple keyboard and mouse-driven browsing, including out-of-the-box
- compatibility with evil-mode,

Installation
------------
To uninstall, use `M-x package-delete RET elpher RET`.
-Usage
------
+Quick Start
+-----------
Once installed, use `M-x elpher` to launch the browser. This will
-open a start page which documents the default key bindings and
-provides some links to help kick start your exploration of gopherspace.
+open a start page which documents the main key bindings and provides
+some links to help kick start your exploration of gopherspace.
+
+From here you can move point between links (which may be menu items or
+inline URLs in text files) by using `TAB` and `Shift-TAB`,
+as in Info. You can also jump directly to a menu item using `m`, or
+use the standard Emacs or Evil motion and search commands to find your
+way around. To open a link, press enter. (Where a mouse is
+available, Clicking on a link with the mouse cursor has the same
+effect.)
+
+To return to the page you just followed the link from, press `u`.
+
+Elpher caches (for the duration of an Emacs session) both page contents
+and the position of point on each of the pages (gopher menus, query
+results, or text pages) you visit, restoring these when you next visit
+the same page. Thus, pressing @key{u} displays the previous page in
+exactly the same state as when you left, meaning that you can quickly
+and visually explore the different documents in a menu without having to
+wait for anything to reload.
+
+Of course, sometimes you'll _want_ to reload the current page
+rather than stick with the cached version. To do this use `R`.
+(This is particularly useful for search query results, where this
+allows you to perform a different search.)
To customize the various faces Elpher uses, the start page
and a few other odds and ends, use the following:
M-x customize-group RET elpher RET
-History and Caching
--------------------
-
-This is an aspect of Elpher that perhaps requires separate explanation.
-
-Every item you visit with Elpher is modeled as a "node" in a tree.
-For instance, a gopher directory represents a single node. When
-you open such a directory, Elpher creates nodes for every entry
-in that directory and makes these children of the original directory node:
-
- X <- current directory node
- |
- -------
- | | |
- o o o <- nodes representing entries in directory
-
-If one of those entries is itself a directory and you click on it,
-Elpher marks that node the current node, and extends the tree as follows:
-
- o <- original directory node
- |
- -------
- | | |
- o o X <- current directory node (marked with X)
- |
- ---------
- | | | | |
- o o o o o <- nodes representing entries in new directory
-
-Pressing the 'u' key (introduced on page which opens when elopher starts)
-always moves to the page representing "parent" node, whatever that is.
-
-Once a node is visited, its "contents" (i.e. whatever is retrieved
-from the gopher server) are recorded in memory with the corresponding
-node. The cursor position (point) is also stored. If the node is
-visited again in the same session, the cached contents are displayed
-and the cursor returns to its previous position. This makes
-navigating amongst different documents referenced from within the same
-directory very snappy. (To conserve memory, this caching isn't by
-default applied to images entries viewed in the browser.)
-
-This hierarchy is also maintained when gopher URLs are followed from plain
-text documents, and when directories are retrieved explicitly using the 'g'
-key. When it is viewed, the bookmark page also becomes a part of this
-hierarchy.
+Full Documentation
+------------------
+
+The full documentation for Elpher can be found in the Info manual,
+which should become automatically available if you install Elpher
+using `M-x package-install`. To access it, select it from the root
+Info directory which can be displayed using `C-h i`.
