+# nvim-surround
+
+**Repository:** https://github.com/kylechui/nvim-surround
+
+Surround selections, stylishly.
+
+## Usage
+
+The three "core" operations of `add`/`delete`/`change` can be done with the
+keymaps `ys{motion}{char}`, `ds{char}`, and `cs{target}{replacement}`,
+respectively. For the following examples, `*` will denote the cursor position:
+
+```help
+    Old text                    Command         New text
+--------------------------------------------------------------------------------
+    surr*ound_words             ysiw)           (surround_words)
+    *make strings               ys$"            "make strings"
+    [delete ar*ound me!]        ds]             delete around me!
+    remove <b>HTML t*ags</b>    dst             remove HTML tags
+    'change quot*es'            cs'"            "change quotes"
+    <b>or tag* types</b>        csth1<CR>       <h1>or tag types</h1>
+    delete(functi*on calls)     dsf             function calls
+```
