 # Comments
 
-Comments are mostly used to add explanations to the code for future readers - which can be yourself. They can also be used to "comment out" code that you want to keep but that should not be run right now, since comments are ignored by the compiler.

+## Documentation Comments
+
+Documentation comments are special [block comments](#block-comments) that are used to document declarations[^1]. The
+documentation is used in various places, e.g. when hovering over a declaration or one of its usage in VS Code. Here is
+an example:
+
+```sds
+/**
+ * This is a documentation comment.
+ */
+class C
+```
+
+They start with `#!sds /**` and end with `#!sds */`. There must be no spaces inside the delimiters. Documentation
+comments cannot be nested. Everything in between the delimiters is the text of the comment, except an optional leading
+asterisk in each line, which is ignored. Documentation comments are attached to the declaration that follows them. If
+there is no declaration following the documentation comment, it is treated as a normal [block comment](#block-comments),
+with no special meaning.
+
+### Markdown
+
+Documentation comments support [Markdown](https://www.markdownguide.org/) to format the text. Here is an example:
+
+```sds
+/**
+ * This is a documentation comment with **bold** and *italic* text.
+ */
+class C
+```
+
+### Tags
+
+Documentation comments can contain tags to provide structured information.
+
+#### `{@link}`
+
+`{@link}` is an **inline** tag that can be used to link to another declaration. It takes the name of the declaration as
+an argument:
+
+```sds
+/**
+ * Computes the sum of two {@link Int}s.
+ */
+fun sum(a: Int, b: Int): sum: Int
+```
+
+#### `@param`
+
+Use `@param` to document a [parameter][parameter] of a callable declaration. This tag takes the name of the parameter
+and its description as arguments. Since a callable can have multiple parameters, this tag can be used multiple times.
+
+```sds
+/**
+ * ...
+ *
+ * @param a The first integer.
+ * @param b The second integer.
+ */
+fun sum(a: Int, b: Int): sum: Int
+```
+
+#### `@result`
+
+Use `@result` to document a [result][result] of a callable declaration. This tag takes the name of the result and its
+description as arguments. Since a callable can have multiple results, this tag can be used multiple times.
+
+```sds
+/**
+ * ...
+ *
+ * @result sum The sum of `a` and `b`.
+ */
+fun sum(a: Int, b: Int): sum: Int
+```
+
+#### `@typeParam`
+
+Use `@typeParam` to document a [type parameter][type-parameter] of a generic declaration. This tag takes the name of the
+type parameter and its description as arguments. Since a generic declaration can have multiple type parameters, this
+tag can be used multiple times.
+
+```sds
+/**
+ * ...
+ *
+ * @typeParam T The type of the elements in the list.
+ */
+class List<T>
+```
+
+#### `@since`
+
+The `@since` tag can be used to specify when a declaration was added. It takes the version as argument and should be
+used only once.
+
+```sds
+/**
+ * ...
+ *
+ * @since 1.0.0
+ */
+fun sum(a: Int, b: Int): sum: Int
+```
+
+[^1]: Except [parameter][parameter], [results][result], and [type parameters][type-parameter], which are documented with
+the [`@param`](#param), [`@result`](#result), and [`@typeParam`](#typeparam) tags on the containing declaration,
+respectively.
