+While the mode is active, the <kbd>C-c C--</kbd> key inserts the
+package namespace if appropriate.
 * Configuration
+** Quickly typing the namespace
+~nameless-mode~ binds the <kbd>C-c C--</kbd> key to
+~nameless-insert-name~, which immediately inserts the current name for
+you, or even expands aliases to the names they point to.
+Let’s say you’re in a file called ~foo-bar.el~.
+#+BEGIN_SRC text
+   C-c C-- → foo-bar-
+fl C-c C-- → font-lock-
+There’s also a command called ~nameless-insert-name-or-self-insert~.
+You can bind this to the <kbd>_</kbd> key and make it even faster to
+insert the name.
+** Configuring the namespace name
+Nameless guesses the package name with the ~lm-get-package-name~
+function, but sometimes this might not match the name you want to use.
+In these situations, simply set ~nameless-current-name~ as file-local variable.
+To do that, invoke the following command:
+#+BEGIN_SRC text
+M-x add-file-local-variable RET nameless-current-name RET "package-name"
+You can also set the same name for all lisp files in a project by
+setting dir-local variables with ~M-x add-file-local-variable~.
+** Requiring other packages as aliases
 Nameless can also be used to “import” other packages as aliases. For
 instance, in the default behaviour, functions in the ~font-lock~
 package (e.g., ~font-lock-add-keywords~) will be displayed with the
 ~fl:~ prefix (e.g., ~fl:add-keywords~).

+** Indentation and paragraph filling
+Hiding parts of symbols could affect the way Emacs indents your code
+and fills your paragraphs. Nameless lets you decide whether you want
+that to happen or not. 
+The default behavior is that code is indented according to what you
+see (i.e., according to short symbols), but text inside strings is
+*not*. So text inside strings will be filled in the same way as if you
+didn’t have ~nameless-mode~. Here’s how a docstring might be filled
+with ~nameless-mode~ enabled:
+#+BEGIN_SRC text
+If point is immediately after an alias configured in the name you
+had in `:aliases' or `:global-aliases', replace
+it with the full name for that alias.
+Altough it may look strange that the second line is so short, that’s
+the correct way. When view on a ~*Help*~ buffer, that docstring will
+look like this:
+#+BEGIN_SRC text
+If point is immediately after an alias configured in the name you
+had in `nameless-aliases' or `nameless-global-aliases', replace
+it with the full name for that alias.
+To change this behavior, configure the variable
