+# ImageMagick for AWS Lambda (Amazon Linux 2)
+
+Scripts to compile ImageMagick utilities for AWS Lambda instances powered by Amazon Linux 2.x, such as the `nodejs10.x` runtime.
+
+Amazon Linux 2 instances for Lambda no longer contain system utilities, so `convert`, `mogrify` and `identify` from the [ImageMagick](https://imagemagick.org) package are no longer available. 
+
+## Prerequisites
+
+* Docker desktop
+* Unix Make environment
+
+## Compiling the code
+
+* `make all`
+
+The `Makefile` in the root directory just starts a Docker container matching the AWS Linux 2 environment for Lambda runtimes, and compiles a static version of ImageMagick tools. They will be in the `result` dir. By default, this compiles a version expecting to run as a Lambda layer from `/opt/imagemagick` (you can change the expected location in the (`Makefile`)[Makefile].
+
+## Bundled libraries
+
+This is not a full-blown ImageMagick setup you can expect on a regular Linux box, it's a slimmed down version to save space that works with the most common formats. You can add more formats by including another library into the build process in [`src/Makefile`](src/Makefile).
+* libpng
+* libtiff
+* libjpeg
+* openjpeg2
