+title = "Custom Exercises"
++++
+
+Custom exercises are a set of exercises maintained by the community.
+You can use the same `rustlings` program that you installed with `cargo install rustlings` to run them:
+
+- 🇯🇵 [Japanese Rustlings](https://github.com/sotanengel/rustlings-jp)：A Japanese translation of the Rustlings exercises.
+- 🇨🇳 [Simplified Chinese Rustlings](https://github.com/SandmeyerX/rustlings-zh-cn): A simplified Chinese translation of the Rustlings exercises.
+
+Do you want to create your own set of Rustlings exercises to focus on some specific topic?
+Or do you want to translate the original Rustlings exercises?

+
+The support of Rustlings for custom exercises allows you to create your own set of Rustlings exercises to focus on some specific topic.
+You could also offer a translation of the original Rustlings exercises as custom exercises.
+
+## Getting started
+
+To create custom exercises, install Rustlings and run `rustlings dev new PROJECT_NAME`.
+This command will, similar to `cargo new PROJECT_NAME`, create a template directory called `PROJECT_NAME` with all what you need to get started.
+
+Read the comments in the generated `info.toml` file to understand its format.
+It allows you to set a custom welcome and final message and specify the metadata of every exercise.
+
+## Create an exercise
+
+Here is an example of the metadata of one file:
+
+```toml
+[[exercises]]
+name = "intro1"
+hint = """
+To finish this exercise, you need to …
+This link might help you …"""
+```
+
+After entering this in `info.toml`, create the file `intro1.rs` in the `exercises/` directory.
+The exercise needs to contain a `main` function, but it can be empty.
+Adding tests is recommended.
+Look at the official Rustlings exercises for inspiration.
+
+You can optionally add a solution file `intro1.rs` to the `solutions/` directory.
+
+Now, run `rustlings dev check`.
+It will tell you about any issues with your exercises.
+For example, it will tell you to run `rustlings dev update` to update the `Cargo.toml` file to include the new exercise `intro1`.
+
+`rustlings dev check` will also run your solutions (if you have any) to make sure that they run successfully.
+
+That's it!
+You finished your first exercise 🎉
+
+## Publish
+
+Now, add more exercises and publish them as a Git repository.
+
+Users just have to clone that repository and run `rustlings` in it to start working on your set of exercises just like the official ones.
+
+One difference to the official exercises is that the solution files will not be hidden until the user finishes an exercise.
+But you can trust the users to not look at the solution too early 😉
+
+## Share
+
+After publishing your set of exercises, open an issue or a pull request in the official Rustlings repository to link to your project in the README 😃
