2. HOW TO USE THE PLUGIN *osc52-how-to-use*

-everything working: >vim
+The osc52.vim package relies on Vim's clipboard provider functionality, see
+|clipboard-providers|. To enable it, add the following to your |vimrc|: >vim
packadd osc52
set clipmethod+=osc52
<
-This will make the osc52.vim provider the last resort if there are other
-values in |clipmethod|. This allows Vim, for example, to access the system
-clipboard directly if it can, but automatically switch to OSC 52 if it cannot
-(e.g. in an SSH session). Note that this does not happen when on a platform
-that doesn't use |clipmethod| for system clipboard functionality (MacOS,
-Windows). If OSC 52 support is detected, then it will always be used if set
-in |clipmethod| when it is the only value/method.
+This appends "osc52" to |clipmethod|, causing Vim to try it only after any
+earlier clipboard methods. This allows Vim to use the system clipboard
+directly when available, and automatically fall back to OSC 52 method when it
+is not (for example, when running over SSH).
+
+Note: that this fallback behavior applies only on platforms that use
+|clipmethod| for accessing the clipboard. On macOS and Windows, Vim does not
+use |clipmethod|, so this behaviour won't happen. Instead if OSC 52 support is
+detected and "osc52" is the only value in |clipmethod|, then it will always be
+used.
+
+You can check whether the osc52.vim provider is active by inspecting
+|v:clipmethod|. If it contains "osc52", the plugin is enabled.
+
+Note: terminal multiplexers such as tmux may interfere with automatic OSC 52
+detection.
*g:osc52_force_avail*
In most cases, the plugin should automatically detect and work if your
-terminal supports the OSC 52 command. Internally, it does this via a Primary
-Device Attributes (DA1) query. You may force enable the plugin by setting
-|g:osc52_force_avail| to true. You may check if the osc52.vim plugin is being
-used if the value of |v:clipmethod| is "osc52". Note that using a terminal
-multiplexer such as tmux, may prevent automatic OSC 52 detection.
