+# Diagnostics
+
+Diagnostics issues may not be suppressed. See [luals](https://luals.github.io) documentation for details on how to structure the code and comments.
+
+Suppressions are permitted only in the following cases:
+
+- Backwards compatibility shims
+- neovim API metadata incorrect, awaiting upstream fix
+- classic class framework
+
+# Backwards Compatibility
+
+Whenever new neovim API is introduced, please ensure that it is available in older versions. See `:help deprecated.txt` and `$VIMRUNTIME/lua/vim/_meta/api.lua`
+
+See `nvim-tree.setup` for the oldest supported version of neovim. If the API is not availble in that version, a backwards compatibility shim must be used e.g.
+
+```lua
+if vim.fn.has("nvim-0.10") == 1 then
+  modified = vim.api.nvim_get_option_value("modified", { buf = target_bufid })
+else
+  modified = vim.api.nvim_buf_get_option(target_bufid, "modified") ---@diagnostic disable-line: deprecated
+end
+```
+
 # Adding New Actions
 
 To add a new action, add a file in `actions/name-of-the-action.lua`. You should export a `setup` function if some configuration is needed.
