+### Stability
+
+One can indicate the stability of an API using the following attributes:
+
+* `deprecated`: This item should no longer be used, e.g. it has been
+  replaced. No guarantee of backwards-compatibility.
+* `experimental`: This item was only recently introduced or is
+  otherwise in a state of flux. It may change significantly, or even
+  be removed. No guarantee of backwards-compatibility.
+* `unstable`: This item is still under development, but requires more
+  testing to be considered stable. No guarantee of backwards-compatibility.
+* `stable`: This item is considered stable, and will not change
+  significantly. Guarantee of backwards-compatibility.
+* `frozen`: This item is very stable, and is unlikely to
+  change. Guarantee of backwards-compatibility.
+* `locked`: This item will never change unless a serious bug is
+  found. Guarantee of backwards-compatibility.
+
+These levels are directly inspired by
+[Node.js' "stability index"](http://nodejs.org/api/documentation.html).
+
+Stability levels are inherited, so an item's stability attribute is the default
+stability for everything nested underneath it.
+
+There are lints for disallowing items marked with certain levels: `deprecated`,
+`experimental` and `unstable`. For now, only `deprecated` warns by default, but
+this will change once the standard library has been stabilized. Stability
+levels are meant to be promises at the crate level, so these lints only apply
+when referencing items from an _external_ crate, not to items defined within
+the current crate. Items with no stability level are considered to be unstable
+for the purposes of the lint. One can give an optional string that will be
+displayed when the lint flags the use of an item.
+
+For example, if we define one crate called `stability_levels`:
+
+```{.ignore}
+#[deprecated="replaced by `best`"]
+pub fn bad() {
+    // delete everything
+}
+
+pub fn better() {
+    // delete fewer things
+}
+
+#[stable]
+pub fn best() {
+    // delete nothing
+}
+```
+
+then the lints will work as follows for a client crate:
+
+```{.ignore}
+#![warn(unstable)]
+extern crate stability_levels;
+use stability_levels::{bad, better, best};
+
+fn main() {
+    bad(); // "warning: use of deprecated item: replaced by `best`"
+
+    better(); // "warning: use of unmarked item"
+
+    best(); // no warning
+}
+```
+
+> **Note:** Currently these are only checked when applied to individual
+> functions, structs, methods and enum variants, *not* to entire modules,
+> traits, impls or enums themselves.
+
