+# Lambda
+
+A simple lambda calculus evaluator. Its just a bunch of functions you define and use as data and pass into other functions.
+
+## How to install
+
+```
+git clone https://github.com/lisk77/lambda && cd lambda
+mkdir build && cd build
+cmake ..
+make
+```
+
+## How to use
+
+Write your code into a file and pipe it into the binary
+
+```
+cat file | lambda
+```
+
+or just echo the code directly
+
+```
+echo "main = \\ x . x;" | lambda
+```
