 # GHAction for the Free Pascal Compiler
 
 This GitHub Action allows you to compile Pascal programs using the Free Pascal Compiler.
+It will parse the compiler's diagnostics and create annotations on your commits and pull requests.

+## Getting FPC
+
+This Action assumes that FPC is already installed in your build environment; it does not handle
+installing it for you. You can do that yourself by adding one of the following steps
+to your GHActions workflow.
+
+### Ubuntu
+
+```
+- name: Install FPC
+  run: |
+     export DEBIAN_FRONTEND=noninteractive
+     sudo apt-get update
+     sudo apt-get install -y fpc
+```
+
+### MacOS
+
+```
+- name: Install FPC
+  run: |
+    brew update
+    brew install fpc
+```
+
+### MS Windows
+
+As of the time of writing, Chocolatey does not have a separate package for FPC,
+so you'll have to install Lazarus instead (it comes with a bundled copy of the compiler).
+
+```
+- name: Install Lazarus
+  run: |
+    choco install lazarus
+```
