 Scarb is the project management tool for the [Cairo] language.
 Scarb manages your dependencies, compiles your projects and works as an extensible platform assisting in development.
 
-## Getting started
+## Documentation
 
-### Installation
+All information about Scarb is available on project's [website](https://docs.swmansion.com/scarb/).
 
-Binary archives for all major platforms (Linux, macOS, Windows) are published on our [GitHub releases] page.
-Simply download suitable one, extract, and move the `scarb` executable to a directory reachable by your `PATH`.
-In the future, an automated installer is planned to be created.
-
-### Creating new project
-
-```shell
-$ scarb new project/directory
-```
-
-_**Also:** There is `scarb init` which runs in current directory instead of creating new one._
-
-### Compiling
-
-```shell
-$ scarb build
-```
-
-Built artifacts will be written to `target/release` directory.
-
-_**Also:** `scarb clean` cleans `target` directory._
-
-#### Building CASM
-
-Add following to `Scarb.toml`:
-
-```toml
-[lib]
-casm = true
-```
-
-_**Also:** Adding `sierra = false` will stop building Sierra code._
-
-#### Building StarkNet contracts
-
-Add following to `Scarb.toml`:
-
-```toml
-[[target.starknet-contract]]
-```
-
-**Note:** Ensure there is no `[lib]` section, they are conflicting
-until https://github.com/software-mansion/scarb/issues/63 will be done.
-
-### Adding dependencies
-
-**Note:** This is identical to Cargo.
-
-#### In manifest
-
-```toml
-[dependencies]
-quaireaux = { path = "path/to/quaireaux" }
-quaireaux = { git = "https://github.com/keep-starknet-strange/quaireaux.git" }
-```
-
-_**Also:** You can add `version` field to specify package version, but this will do more harm than good currently, Scarb
-lacks proper version solution algorithm yet._
-
-_**Also:** You can add `branch`, `tag` and `rev` fields to Git dependencies._
-
-_**Also:** You can use `ssh://` URLs, Scarb uses local `git` installation for all network operations._
-
-#### Via `scarb add`
-
-```shell
-$ scarb add quaireaux --path path/to/quaireaux
-$ scarb add quaireaux --git https://github.com/keep-starknet-strange/quaireaux.git
-```
-
-_**Also:** You can specify package version like this: `[email protected]`, but see remarks in previous section._
-
-_**Also:** `--git` supports `--branch`, `--tag` and `--rev` arguments._
-
-_**Also:** `scarb rm` removes a dependency._
-
-### Formatting
-
-```shell
-# Format Cairo code:
-$ scarb fmt
-
-# Check formatting in CI:
-$ scarb fmt -c
-```
