+### How to run
+
+Run [main](src/main/java/ru/itmo/simplecli/Main.java)
+method from IDE **or** `./gradlew run`.
+
+### What's there
+
+Implemented build-ins:
+- [cat](src/main/java/ru/itmo/simplecli/executor/commands/Cat.java)
+- [echo](src/main/java/ru/itmo/simplecli/executor/commands/Echo.java)
+- [exit](src/main/java/ru/itmo/simplecli/executor/commands/Exit.java)
+- [pwd](src/main/java/ru/itmo/simplecli/executor/commands/Pwd.java)
+- [wc](src/main/java/ru/itmo/simplecli/executor/commands/WC.java)
+- [variable assignment](src/main/java/ru/itmo/simplecli/executor/commands/Assignment.java)
+
+[Main](src/main/java/ru/itmo/simplecli/Main.java) runs loop until `exit` command is given.
+If the entered string contains incomplete quotes, it asks to continue typing.
+
+[Parser](src/main/java/ru/itmo/simplecli/executor/Parser.java) supports double and single quotes.
+It also performs substitution for values beginning with `$` if it is not surrounded by single quotes.
+
+The CLI [supports](src/main/java/ru/itmo/simplecli/executor/PipedCommand.java) a pipeline of commands, separated by a sign `|`,
+each command receives as input the output of the previous one.
