+             :: Customizing the Landing Page ::
+
+    If you like, feel free to customize the landing page
+ template provided at 
+
+        assets/tmpl/index.html
+
+    It must be standard HTML or XHTML. There are a few special 
+ tags available to use that will be replaced with specific values 
+ when the template is parsed by getwtxt.
+
+    Values are derived from the "Instance" section of the 
+ configuration file, except for the version of getwtxt used. The 
+ following will be in the form of:
+    
+    {{.TemplateTag}} What it will be replaced with when
+        the template is processed and the landing page is
+        served to a visitor.
+
+    The surrounding double braces and prefixed period are required 
+ if you choose to use these tags in your modified landing page. The
+ tags themselves are not required; access to them is provided simply
+ for convenience.
+
+    {{.Vers}} The version of getwtxt used. Does not include
+        the preceding 'v'. Ex: 0.2.0
+
+    {{.Name}} The name of the instance.
+
+    {{.Owner}} The instance owner's name.
+
+    {{.Mail}} Email address used for contacting the instance
+        owner if the need arises.
+
+    {{.Desc}} Short description placed in the configuration
+        file. This is why HTML tags are allowed.
+
+    {{.URL}} The publicly-accessible URL of your instance. In
+        the default landing page, example API calls are shown
+        using this URL for the convenience of the user.
+
+
+              :: Interacting with the Registry ::
+
+    The registry API is rather simple, and can be interacted with
+ via the command line using cURL. Example output of the calls will
+ not be provided. 
+
+    Pseudo line-breaks will be represented with a backslash. 
+ Examples with line-breaks are not syntactically correct and will
+ be rejected by cURL. Please concatenate the example calls without 
+ the backslash. This is only present to maintain consistent 
+ formatting for this manual text.
+
+    Ex: 
+        /api/plain/users\
+        ?q=FOO
+    Should be: 
+        /api/plain/users?q=FOO
+
+    All queries (every call except adding users) accept the
+ ?page=N parameter, where N > 0. The output is provided in groups 
+ of 20 results. For example, indexed at 1, ?page=2 (or &page=2 if 
+ it is not the first parameter) appended to any query will return 
+ results 21 through 40. If the page requested will exceed the 
+ bounds of the query output, the last 20 query results are returned.
+
+ Adding a user:
+    curl -X POST 'http://localhost:9001/api/plain/users\
+        ?url=https://gbmor.dev/twtxt.txt&nickname=gbmor'
+
+ Retrieve user list:

+
+ Retrieve all statuses:
+    curl 'http://localhost:9001/api/plain/tweets'
+
+ Retrieve all statuses with mentions:
+    curl 'http://localhost:9001/api/plain/mentions'
+
+ Retrieve all statuses with tags:
+    curl 'http://localhost:9001/api/plain/tags'
+
+ Query for users by keyword:
+    curl 'http://localhost:9001/api/plain/users?q=FOO'
+
+ Query for users by URL:
+    curl 'http://localhost:9001/api/plain/users\
+        ?url=https://gbmor.dev/twtxt.txt'
+
+ Query for statuses by substring:
+    curl 'http://localhost:9001/api/plain/tweets\
+        ?q=SUBSTRING'
+
+ Query for statuses mentioning a user:
+    curl 'http://localhost:9001/api/plain/mentions\
+        ?url=https://gbmor.dev/twtxt.txt'
+
+ Query for statuses with a given tag:
