+# Building OpenJDK as static PIE
+
+Build the [OpenJDK](https://openjdk.org/)(v20) as a static PIE ELF.
+
+## Requirements:
+
+Make sure the following packages are installed:
+* gcc >= 8
+* autoconf
+* zip
+* alsa
+* cups
+* fontconfig
+* X11
+* JDK v19
+
+## Build
+
+If you want to build `OpenJDK`, run:
+
+```
+$ bash build.sh
+```
+
+This will create a directory named 'out' where the `OpenJDK` will be located.
+
+If you want to clean everything and rebuild it, run:
+
+```
+$ bash build.sh clean
+```
