=== Viewing documentation for Substrate packages
You can generate documentation for a Substrate Rust package and have it automatically open in your web browser using https://doc.rust-lang.org/rustdoc/what-is-rustdoc.html#using-rustdoc-with-cargo[rustdoc with Cargo],
(of the The Rustdoc Book), by running the the following command:
```
cargo doc --package <spec> --open
```
Replacing `<spec>` with one of the following (i.e. `cargo doc --package node-cli --open`):
* Substrate Core
[source, shell]
substrate, substrate-bft, substrate-cli, substrate-client, substrate-client-db,
substrate-executor, substrate-finality-grandpa, substrate-keyring, substrate-keystore,
substrate-metadata, substrate-misbehavior-check, substrate-network,
substrate-network-libp2p, substrate-primitives, substrate-rpc, substrate-rpc-servers,
substrate-serializer, substrate-service, substrate-service-test, substrate-state-db,
substrate-state-machine, substrate-telemetry, substrate-test-client,
substrate-test-runtime, substrate-transaction-graph, substrate-transaction-pool,
substrate-trie
* Substrate Runtime
[source, shell]
sr-api, sr-io, sr-primitives, sr-sandbox, sr-std, sr-version
* Substrate Runtime Module Library (SRML)
[source, shell]
srml-balances, srml-consensus, srml-contract, srml-council, srml-democracy, srml-example,

=== Contributing to documentation for Substrate packages
https://doc.rust-lang.org/1.9.0/book/documentation.html[Document source code] for Substrate packages by annotating the source code with documentation comments.
Example (generic):
```markdown
/// Summary
///
/// Description
///
/// # Panics
///
/// # Errors
///
/// # Safety
///
/// # Examples
///
/// Summary of Example 1
///
/// ```rust
/// // insert example 1 code here
/// ```
///
```
* Important notes:
** Documentation comments must use annotations with a triple slash `///`
** Modules are documented using `//!`
```
//! Summary (of module)
//!
//! Description (of module)
```
* Special section header is indicated with a hash `#`.
** `Panics` section requires an explanation if the function triggers a panic
** `Errors` section is for describing conditions under which a function of method returns `Err(E)` if it returns a `Result<T, E>`
** `Safety` section requires an explanation if the function is `unsafe`
** `Examples` section includes examples of using the function or method
* Code block annotations for examples are included between triple graves, as shown above.
Instead of including the programming language to use for syntax highlighting as the annotation
after the triple graves, alternative annotations include the `ignore`, `text`, `should_panic`, or `no_run`.
* Summary sentence is a short high level sinngle sentence of its functionality
* Description paragraph is for details additional to the summary sentence
* Missing documentation annotations may be used to identify where to generate warnings with `#![warn(missing_docs)]`
or errors `#![deny(missing_docs)]`
* Hide documentation for items with `#[doc(hidden)]`
=== Contributing to documentation (tests, extended examples, macros) for Substrate packages
The code block annotations in the `# Example` section may be used as https://doc.rust-lang.org/1.9.0/book/documentation.html#documentation-as-tests[documentation as tests and for extended examples].
* Important notes:
** Rustdoc will automatically add a `main()` wrapper around the code block to test it
** https://doc.rust-lang.org/1.9.0/book/documentation.html#documenting-macros[Documentating macros].
** Documentation as tests examples are included when running `cargo test`
