+## License
+
+This repository holds two licenses, as you can also note on the `Cargo.toml`
+file. As it's written there:
+
+- The source code on the `crates/` directory is licensed under the GNU GPLv3 (or
+  any later version).
+- The source code on the `lib/` directory is licensed under the GNU LGPLv3 (or
+  any later version).
+
+In practice, for the libraries under `lib/` this means that if you plan to
+compile your binary statically, you still need to abide by the LGPLv3+ license.
+This means at least providing the object files necessary to allow someone to
+recompile your program using a modified version of these libraries. See the
+LGPLv3 license for more details.
