+## Why?
+
+Do you want to fix an error you have found? Do you know a way to improve my
+6502-fu or do you know a technique on NES development that might help here? I am
+open for discussion and welcome any help!
+
+## How?
+
+There are many ways to help me out. One way might be to open an issue on
+[Github's tracker](https://github.com/mssola/list.nes/issues) and start a
+discussion. For this, mind the following:
+
+- Check that the issue has not already been reported or fixed in `main`.
+- Try to be concise and precise in your description.
+- If you have found a problem, provide a step by step guide on how to reproduce it.
+- Provide the version you are using (git commit SHA), as well as the version of
+  the toolchain and the emulator/system being used.
+
+Another way is to simply submit a pull request. For this, also mind these:
+
+- Write a [good commit message](https://chris.beams.io/posts/git-commit/).
+- You are sure that `make` continues to work.

+# Security Policy
+
+This is not a serious kernel, and hence we do not have any serious security
+policy. There are of course many things that could compromise a toy kernel such
+as this. For example:
+
+- Bad bound checks that could turn into a vector of attacks.
+- Bad enforcements of memory protection.
+  - Remember that this kernel does not implement any memory protection on the
+    purpose of being simple, but we could always enable other mechanisms to keep
+    things "secure".
+- Other kind of bugs that could compromise such as kernel.
+
+For any of these situations, since this is a toy project, simply submit an
+[issue to the Github repository](https://github.com/mssola/fbos/issues).
