 ### Text Options
 
-The `text` table supports both static strings and functions for dynamic content. These are simplified placeholders, the default configuration uses a function to dynamically set the context.
+The `text` table allows you to customize the displayed text for different states. You can customize it in three different ways:
 
+1. Using simple strings:
+```lua
+text = {
+    editing = 'Editing a file',
+    viewing = 'Viewing a file',
+}
+```
+
+2. Using functions for dynamic text:
 ```lua
 text = {
     editing = function(opts)
         return string.format('Editing %s', opts.filename)
     end,
-    viewing = 'Viewing a file',                 -- Simple string with filename placeholder
-    file_browser = 'Browsing files',            -- Shown in file explorer
-    plugin_manager = 'Managing plugins',        -- Shown in plugin manager
-    lsp_manager = 'Configuring LSP',            -- Shown in LSP manager
-    docs = 'Reading docs',                      -- Shown in help buffers
-    vcs = 'Committing changes',                 -- Shown in VCS related filetypes
-    notes = 'Taking notes',                     -- Shown in notes-taking related filetypes
-    dashboard = 'Home',                         -- Shown in dashboard buffers
-    workspace = 'Workspace: ${workspace_name}', -- `variables` must be set in order to use string templates `${}`
 }
 ```
 
+3. Using string templates (requires enabling variables):
+```lua
+{
+    text = {
+        editing = 'Editing ${filename}',
+        file_browser = 'Browsing files in ${tooltip}',
+    },
+    variables = true, -- Enable string templates
+}
+```
