+# sd - s[earch] & d[isplace]
+
+`sd` is a simple, user-friendly find & replace command line tool.
+
+## Features
+
+**Painless regular expressions**
+
+Use regex syntax that you already know from JavaScript, Python, and Rust. No need to learn  special syntax or eccentrisms of `sed` or `awk`. Easily access your captured groups with `$1`, `$2`.
+
+**String-literal mode**
+
+In string-literal mode, you don't need to escape any special characters - its simply unnecessary.
+
+**Easy to read, easy to write**
+
+Find & replace expressions are split up and in most cases unescaped, which contributes to readability and makes it easier to spot errors in your regexes.
+
+## Comparison to sed
+
+While sed is frighteningly powerful, `sd` focuses on doing just one thing and doing it well.
+
+Some cherry-picked examples, where `sd` shines:
+- Replace newlines with commas:
+  - sed: `sed ':a;N;$!ba;s/\r/,/g'` vs
+  - sd: `sd -r '\r' ','`
+- Extracting stuff out of strings with special characters
+  - sd: `echo "{((sample with /path/))}" | sd -r '\{\(\(.*(/.*/)\)\)\}' '$1'`
+  - sed
+    - incorrect, but closest I could get after 15 minutes of struggle
+    - `echo "{((sample with /path/))}" | sed 's/{((\.\*\(\/.*\/\)))}/\1/g'`
+
+Note: although `sed` has a nicer regex syntax with `-r`, it is not portable and doesn't work on, say, MacOS or Solaris.
