+  sttr: A cross-platform, cli app to perform various operations on string
+---
+
+To update or switch versions, run `webi sttr@stable` (or `@v0.2.16` etc).
+
+## Cheat Sheet
+
+> `sttr` makes it easy to perform various operations on string.
+
+
+## Basic Usage
+
+* After installation simply run `sttr` command.
+
+```sh
+// For interactive menu
+sttr
+// Provide your input
+// Press two enter to open operation menu
+// Press `/` to filter various operations.
+// Can also press UP-Down arrows select various operations.
+```
+
+* Working with help.
+
+```sh
+sttr -h
+
+// Example
+sttr zeropad -h
+sttr md5 -h
+```
+
+* Working with files input.
+
+```sh
+sttr {command-name} {filename}
+
+sttr base64-encode image.jpg
+sttr md5 file.txt
+sttr md-html Readme.md
+```
+
+* Writing output to file.
+
+```sh
+sttr yaml-json file.yaml > file-output.json
+```
+
+* Taking input from other command.
+
+```sh
+curl https: //jsonplaceholder.typicode.com/users | sttr json-yaml
+```
+
+* Chaining the different processor.
+
+```sh
+sttr md5 hello | sttr base64-encode
+
+echo "Hello World" | sttr base64-encode | sttr md5
+```
