+## unstable_feature_bound
+The `#[unstable_feature_bound(foo)]` attribute can be used together with `#[unstable]` attribute to mark an `impl` of stable type and stable trait as unstable. In std/core, an item annotated with `#[unstable_feature_bound(foo)]` can only be used by another item that is also annotated with `#[unstable_feature_bound(foo)]`. Outside of std/core, using an item with `#[unstable_feature_bound(foo)]` requires the feature to be enabled with `#![feature(foo)]` attribute on the crate. Currently, only `impl`s and free functions can be annotated with `#[unstable_feature_bound]`.

+## Testing tests on wasi (wasm32-wasip1)
+
+Some tests are specific to wasm targets.
+To run theste tests, you have to pass `--target wasm32-wasip1` to `x test`.
+Additionally, you need the wasi sdk.
+Follow the install instructions from the [wasi sdk repository] to get a sysroot on your computer.
+On the [wasm32-wasip1 target support page] a minimum version is specified that your sdk must be able to build.
+Some cmake commands that take a while and give a lot of very concerning c++ warnings...
+Then, in `bootstrap.toml`, point to the sysroot like so:
+
+```
+[target.wasm32-wasip1]
+wasi-root = "<wasi-sdk location>/build/sysroot/install/share/wasi-sysroot"
+```
+
+In my case I git-cloned it next to my rust folder, so it was `../wasi-sdk/build/....`
+Now, tests should just run, you don't have to set up anything else.
