+# prelude.kak
+
+Prelude of shell blocks for [Kakoune].
+
+## Installation
+
+Add [`prelude.kak`](rc/prelude.kak) to your autoload or source it manually.
+
+## Usage
+
+```
+kak_escape [text…]
+```
+
+Similar to `shell_escape` you may find in other programming languages,
+`kak_escape` escapes each argument so that it can be safely passed to Kakoune.
+
+**Implementation**:
+Single quotes each argument and doubles the single quotes inside.
+
+**Note**:
+The resulted text should be used unquoted and is not intended for use in double quotes, nor in single quotes.
+
+**Example**:
+
+``` kak
+evaluate-commands %sh{
+  . "$kak_opt_prelude"
+  kak_escape evaluate-commands -try-client "$kak_client" 'echo Tchou' | kak -p "$kak_session"
+}
+```
