+Truncation                             Feline has an automatic smart truncation
+                                       system where components can be
+                                       automatically truncated if the
+                                       statusline doesn’t fit within the
+                                       window. There’s a few component values
+                                       associated with truncation.
+
+
+COMPONENT SHORT PROVIDER
+
+`short_provider` is an optional component value that allows you to take
+advantage of Feline’s truncation system. Note that this should only be
+defined if you want to enable truncation for the component, otherwise it’s
+absolutely fine to omit it.
+
+`short_provider` works just like the `provider` value, but is activated only
+when the component is being truncated due to the statusline not fitting within
+the window. `short_provider` is independent from the `provider` value so it can
+be a different provider altogether, or it can be a shortened version of the
+same provider or the same provider but with a different `opts` value. For
+example:
+
+>
+    -- In this component, short provider uses same provider but with different opts
+    local file_info_component = {
+        provider = {
+            name = 'file_info',
+            opts = {
+                type = 'full-path'
+            }
+        },
+        short_provider = {
+            name = 'file_info',
+            opts = {
+                type = 'short-path'
+            }
+        }
+    }
+    
+    -- Short provider can also be an independent value / function
+    local my_component = {
+        provider = 'loooooooooooooooong',
+        short_provider = 'short'
+    }
+<
+
+
+Feline doesn’t set `short_provider` to any component by default, so it must
+be provided manually.
+
+HIDE COMPONENTS DURING TRUNCATION
+
+If you wish to allow Feline to hide a component entirely if necessary during
+truncation, you may set the `truncate_hide` component value to `true`. By
+default, `truncate_hide` is `false` for every component.
+
+COMPONENT PRIORITY
+
+When components are being truncated by Feline, you can choose to give some
+components a higher priority over the other components. The `priority`
+component value just takes a number. By default, the priority of a component is
+`0`. Components are truncated in ascending order of priority. So components
+with lower priority are truncated first, while components with higher priority
+are truncated later on. For example:
+
+>
+    -- This component has the default priority
+    local my_component = {
+        provider = 'loooooooooooooooong',
+        short_provider = 'short'
+    }
+    -- This component has a higher priority, so it will be truncated after the previous component
+    local high_priority_component = {
+        provider = 'long provider with high priority',
+        short_provider = 'short',
+        priority = 1
+    }
+<
+
+
+Priority can also be set to a negative number, which can be used to make a
+component be truncated earlier than the ones with default priority.
