 # Assists
 
+## `add_derive`
+
+Adds a new `#[derive()]` clause to a struct or enum.
+
+```rust
+// BEFORE
+struct Point {
+    x: u32,
+    y: u32,<|>
+}
+
+// AFTER
+#[derive()]
+struct Point {
+    x: u32,
+    y: u32,
+}
+```
+
+## `add_explicit_type`
+
+Specify type for a let binding
+
+```rust
+// BEFORE
+fn main() {
+    let x<|> = 92;
+}
+
+// AFTER
+fn main() {
+    let x: i32 = 92;
+}
+```
+
+## `add_impl`
+
+Adds a new inherent impl for a type
+
+```rust
+// BEFORE
+struct Ctx<T: Clone> {
+     data: T,<|>
+}
+
+// AFTER
+struct Ctx<T: Clone> {
+     data: T,
+}
+
+impl<T: Clone> Ctx<T> {
+
+}
+```
+
+## `add_impl_default_members`
+
+Adds scaffold for overriding default impl members
+
+```rust
+// BEFORE
+trait T {
+    Type X;
+    fn foo(&self);
+    fn bar(&self) {}
+}
+
+impl T for () {
+    Type X = ();
+    fn foo(&self) {}<|>
+
+}
+
+// AFTER
+trait T {
+    Type X;
+    fn foo(&self);
+    fn bar(&self) {}
+}
+
+impl T for () {
+    Type X = ();
+    fn foo(&self) {}
+    fn bar(&self) {}
+
+}
+```
+
+## `add_impl_missing_members`
+
+Adds scaffold for required impl members
+
+```rust
+// BEFORE
+trait T {
+    Type X;
+    fn foo(&self);
+    fn bar(&self) {}
+}
+
+impl T for () {<|>
+
+}
+
+// AFTER
+trait T {
+    Type X;
+    fn foo(&self);
+    fn bar(&self) {}
+}
+
+impl T for () {
+    fn foo(&self) { unimplemented!() }
+
+}
+```
+
+## `apply_demorgan`
+
+Apply [De Morgan's law](https://en.wikipedia.org/wiki/De_Morgan%27s_laws).
+This transforms expressions of the form `!l || !r` into `!(l && r)`.
+This also works with `&&`. This assist can only be applied with the cursor
+on either `||` or `&&`, with both operands being a negation of some kind.
+This means something of the form `!x` or `x != y`.
+
+```rust
+// BEFORE
+fn main() {
+    if x != 4 ||<|> !y {}
+}
+
+// AFTER
+fn main() {
+    if !(x == 4 && y) {}
+}
+```
+
 ## `convert_to_guarded_return`
 
 Replace a large conditional with a guarded return.
