 ## Symlink alternates
 
 It can be useful to have an automated way of choosing an alternate version of a
-file for a different operating system, host, or user. yadm implements a
-feature which will automatically create a symbolic link to the appropriate
-version of a file, as long as you follow a specific naming convention. yadm can
-detect files with names ending in:
+file for a different operating system, host, user, etc.
 
-| `##`                       | Default file linked                  |

+yadm will automatically create a symbolic link to the appropriate version of a
+file, when a valid suffix is appended to the filename. The suffix contains the
+conditions that must be met for that file to be used.
 
-If there are any files managed by yadm's repository, or listed in

-If running on a Macbook named `host2`, yadm will create a symbolic link which
-looks like this:
+Each condition is an attribute/value pair, separated by a period. Some
+conditions do not require a "value", and in that case, the period and value can
+be omitted. Most attributes can be abbreviated as a single letter.
 
-`$HOME/path/example.txt` → `$HOME/path/example.txt##Darwin.host2`
+| Attribute | Meaning |
+| - | - |
+| `template`, `t` | Valid when the value matches a supported template processor. See the [Templates](/docs/templates) section for more details.|
+| `user`, `u` | Valid if the value matches the current user. Current user is calculated by running <code>id&nbsp;&#8209;u&nbsp;&#8209;n</code>. |
+| `distro`, `d` | Valid if the value matches the distro. Distro is calculated by running <code>lsb_release&nbsp;&#8209;si</code>. |
+| `os`, `o` | Valid if the value matches the OS. OS is calculated by running <code>uname&nbsp;&#8209;s</code>. |
+| `class`, `c` | Valid if the value matches the local.class configuration. Class must be manually set using <code>yadm&nbsp;config&nbsp;local.class&nbsp;&lt;class&gt;</code>. |
+|`hostname`, `h`|Valid if the value matches the short hostname. Hostname is calculated by running `hostname`, and trimming off any domain.|
+|`default`|Valid when no other alternate is valid.|
 
-However, on another Macbook named `host3`, yadm will create a symbolic link
-which looks like this:
+You may use any number of conditions, in any order. An alternate will only be
+used if _ALL_ conditions are valid. For all files managed by yadm's repository
+or listed in `$HOME/.config/yadm/encrypt`, if they match this naming convention,
+symbolic links will be created for the most appropriate version.
 
-`$HOME/path/example.txt` → `$HOME/path/example.txt##Darwin`
+The "most appropriate" version is determined by calculating a score for each
+version of a file. A [template](/docs/templates) is always scored higher than
+any symlink condition. The number of conditions is the next largest factor in
+scoring. Files with more conditions will always be favored. Any invalid
+condition will disqualify that file completely.
 
-Since the host name doesn't match any of the  managed  files,  the  more generic
-version is chosen.
+If you don't care to have all versions of alternates stored in the same
+directory as the generated symlink, you can place them in the

 ## Class and Overrides
 
 Class is a special value which is stored locally on each host (inside the local
-repository). To use alternate symlinks using `CLASS`, you must set the value of
-class using the configuration `local.class`. This is set like any other yadm
-configuration—with the `yadm config` command. The following sets the `CLASS` to
-be "Work".

+Templates are a special kind of [alternate](/docs/alternates) file. The template
+content and host specific data are combined as input to a template processor
+which produces a new file as its output.
+
+This can be very useful if you need to vary a small part of a file, but it
+doesn't support any kind of include directive.
+
+## Template suffixes
+
+To create a template, append an alternate suffix to the file name.

+
+## Supported template processors
+
+default
+: This built-in processor requires no additional software (assuming your distro
+contains `awk`). This processor has a syntax _similar_ to the Jinja processors
+below, however it only supports a small set of directives. Those directives are
+detailed in the section below.
+
+j2cli
+: [j2cli][j2cli] (or `j2`) is a Python-based Jinja2 template processor. This
+fully supports all directives of the [Jinja2 library][jinja]. When your template is
+processed, the YADM_* values are provided to j2cli as environment variables.
+
+envtpl
+: [envtpl][envtpl] is another Python-based Jinja2 template processor. Online
+comments suggest this software might not be maintained anymore.
+
+## Built-in directives
+yadm's "default" (built-in) template processor supports the following directives.
+
+{% raw %}
+variables
+: Variables should be surrounded by `{{ }}`. It is fine for there to be
+whitespace between the variable name and the double braces. The `{{` and
+`}}` must be on the same line. For example:
+
+```jinja
+# WARNING: Do not edit this file.
+# It was generated by processing {{ yadm.source }}
+```
+
+if-else-endif
+: Entire blocks of content can be included or excluded based on the value of a
+variable. Only equality can be tested. These blocks must start with
+`{% if yadm.variable == "value" %}` and end with `{% endif %}`. An alternative
+block can also be specified using the directive `{% else %}`. These directives
+must appear on lines by themselves. They may not appear on the same line. The
+"if" directive only supports testing a single variable, and there is no "elif"
+directive as there is in Jinja. Here is an example.
+
+```jinja
+{% if yadm.os == "Darwin" %}
+This block is included for MacOS
+{% else %}
+This block is included for for any other OS
+{% endif %}

+Beginning with version 2.0.0, yadm introduced a few major changes which may
+require you to adjust your configurations.
+
+If you want to retain yadm's old behavior until you transition your
+configurations, you can set an environment variable `YADM_COMPATIBILITY=1`.
+Doing so will automatically use the old yadm directory, and process alternates the same as version 1.
+This compatibility mode is deprecated, and will be removed in future versions.
+This mode exists solely for transitioning to the new paths and naming of alternates.
+
+## New yadm directory location
+yadm now uses the [XDG Base Directory Specification][xdg-spec] to find its configurations.
+For the majority of users, this means configurations will now be in
+`$HOME/.config/yadm` instead of the old location of `$HOME/.yadm`.
+
+You can customize the base directory by specifying an environment variable
+named `XDG_CONFIG_HOME`.
+
+If you previously had configurations in `$HOME/.yadm`, the easiest way
+to migrate is to use the new `yadm upgrade` command. This command will move your
+existing repo and configurations to the new directory, and rename any yadm
+configurations that are tracked by your repo.
+
+## New alternate file naming convention
+The naming conventions for alternate files have been changed.
+Read full details about the new naming convention [here](/docs/alternates).
+
+This table of examples should help you understand how to translate old filenames
+to new ones.

+
+## Built-in template processing
+Older versions supported Jinja templates if envtpl was installed. New versions
+support _multiple_ template processors, including a built-in processor. The
+built-in processor has a limited feature set, but should be sufficient for most
+users needs (without having to install additional software). Read full details
+[here](/docs/templates).
+
+## Option `yadm.cygwin-copy` changed to `yadm.alt-copy`
+Older versions supported a `yadm.cygwin-copy` option, because some software
+doesn't work well with CYGWIN symlinks. Now that option has been renamed to
+`yadm.alt-copy`, and can be used on any system, not just CYGWIN. So if you have
+a system which doesn't fully support symlinks, you can have alternates created
+as files instead.
