+This directory contains the native files of libraries that were modified for relocation. They will be copied from here during the normal build steps.
+
+Before adding/updating a library, make sure you have Python 3.8+ installed and check the instructions below.
+
+How to add a library's natives:
+
+1. In `build.gradle`:
+
+- Make sure the target package is the same length or shorter (untested) than the source package. Underscores in native methods will be mapped to `_1` so account for that as well.
+- Exclude the native files and add them as `relocateNative` (see example).
+
+Example:
+
+```groovy
+relocate "org.sqlite", "dh_sqlite", {
+    exclude "org/sqlite/native/**"
+}
+
+transform(NativeTransformer) {
+    // NativeTransformer configuration
+    rootDir = project.rootDir
+
+    // Replace native strings, e.g. used in calls back to Java
+    relocateNative "org/sqlite", "dh_sqlite"
+    // Rename native methods used when calling from Java
+    relocateNative "org_sqlite", "dh_1sqlite"
+}
+```
+
+How to update a library's natives:
+
+1. Delete the library's folder in cache/.
+2. It will repopulate during the next build.
+
+Why does this step exist?
+
+- Native files are not handled by the shadow plugin correctly.
+- I preferred it as a more streamlined approach, although a bit hacky.
+- Possible alternatives:
+    - Use edited libraries' source code: although more straightforward, it requires maintaining and updating the repositories for the libraries being added
+    - Interfacing with the necessary libraries directly: an absolute mess for technical reasons
+
+What are libraries used?
+
+- LIEF: for fixing binaries after replacing strings
+- apple-codesign: for re-signing Mac binaries, since their signatures get invalidated after previous steps
