+
+Use the OSC 52 terminal command for clipboard support
+==============================================================================
+
+1. OVERVIEW *osc52-overview*
+
+The osc52.vim plugin provides support for the OSC 52 terminal command, which
+allows an application to access the clipboard by communicating with the
+terminal. This is useful in situations such as if you are in a SSH session.
+
+ *osc52-support*
+In order for this plugin to work, the terminal Vim is running in must
+recognize and handle the OSC 52 escape sequence. You can easily check this
+online. Additionally, while yanking is guaranteed to work, some terminals
+don't implement the paste functionality. If the terminal doesn't support
+pasting, then Vim will just block waiting for the data which will never come.
+In this case just press Ctrl-C to cancel the operation.
+
+ *osc52-selections*
+Note that this only applies to users on Wayland or X11 platforms
+
+Some terminals support the selection type parameter in the OSC 52 command.
+This originates from X11, and some terminals check this parameter and handle
+it accordingly. If your terminal handles this parameter, then the "+"
+register corresponds to the regular selection, and the "*" register
+corresponds to the primary selection. If your terminal does not handle it,
+then it is up to the terminal to handle what selection to use.
+
+2. HOW TO USE THE PLUGIN *osc52-how-to-use*
+
+The osc52.vim plugin relies on Vim's clipboard provider functionality, see
+|clipboard-providers|. In short, add these commands to your vimrc to get
+everything working: >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.
+
+ *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.
+
+ *g:osc52_disable_paste*
+If your terminal does not support pasting via OSC 52, or has it disabled, then
+it is a good idea to set g:osc52_disable_paste to TRUE. This will cause an
+empty string to be returned when Vim attempts to query the osc52.vim provider,
+instead of doing a blocking wait, as said in |osc52-support|.
