+# Migrating from RTFM to RTIC
+
+This section covers how to upgrade an application written against RTFM v0.5.x to
+the same version of RTIC. This applies since the renaming of the framework as per [RFC #33].
+
+**Note:** There are no code differences between RTFM v0.5.3 and RTIC v0.5.3, it is purely a name
+change.
+
+[RFC #33]: https://github.com/rtic-rs/rfcs/pull/33
+
+## `Cargo.toml`
+
+First, the `cortex-m-rtfm` dependency needs to be updated to
+`cortex-m-rtic`.
+
+``` toml
+[dependencies]
+# change this
+cortex-m-rtfm = "0.5.3"
+
+# into this
+cortex-m-rtic = "0.5.3"
+```
+
+## Code changes
+
+The only code change that needs to be made is that any reference to `rtfm` before now need to point
+to `rtic` as follows:
+
+``` rust
+//
+// Change this
+//
+
+#[rtfm::app(/* .. */, monotonic = rtfm::cyccnt::CYCCNT)]
+const APP: () = {
+    // ...
+
+};
+
+//
+// Into this
+//
+
+#[rtic::app(/* .. */, monotonic = rtic::cyccnt::CYCCNT)]
+const APP: () = {
+    // ...
+
+};
+```
