+# Project initialization
+
+## Creating a project
+To create a new Protostar project with cairo1 support, you will need to run the `protostar init-cairo1` command followed by the name of your project. For example:
+
+```shell
+protostar init-cairo1 my-project
+```
+
+After running the command, the following structure will be generated:
+
+```
+my-project/
+├── src/
+│   └── main.cairo
+│   └── lib.cairo
+│   └── cairo_project.toml
+├── tests/
+│   └── test_main.cairo
+└── protostar.toml
+```
+
+This template contains:
+
+- `src` directory
+    - `cairo_project.toml` which is needed for compilation 
+    - `main.cairo` file with one function definition
+    - `lib.cairo` file which defines the module
+- `test` directory
+    - Single test file with one test for function defined in `main.cairo`
+- `protostar.toml` containing information about the project
+
+## The protostar.toml
+Apart from the usual things you can find in `protostar.toml`, there is a `linked-libarires` entry which is used to find cairo 1 modules in tests and building.
+This makes it possible for you to include other modules from your dependencies if they are correct cairo 1 modules (with their own module definition and `cairo_project.toml`).
+
+```
+[project]
+protostar-version = "0.9.2"
+lib-path = "lib"
+linked-libraries = ["src"]
+
+[contracts]
+```
+
+:::warning
+`[contracts]` section is not usable right now, since protostar can't build cairo 1 contracts yet
