+If your Pull Request involves changes in the docs folder, please add the `documentation` flag and request an approval by a DevRel team member[^1]. An approval from DevRel is not necessary to merge your PR.
 
 ### With Breaking Changes
 
+Breaking changes need to be documented. Please ask for help from a DevRel[^1] team member if this is a problem for any reason. Breaking changes need a mandatory approval from DevRel.
+
 Sometimes, we don't merge pull requests with breaking changes immediately upon approval. Since a breaking change will cause Noir to bump to the next "minor" version, we might want to land some fixes in "patch" releases before we begin working on that next breaking version.
 
 ## Merging

 - Is continuous integration passing?
 - Do you have the required amount of approvals?

 When we are ready to release the version, we approve and squash the release pull request into `master`. Release Please will detect this merge and generate the appropriate tags for the release. Additional release steps may be triggered inside the GitHub Action to automate other parts of the release process.
 
+### Documentation releases
+
+We aim to have every documentation version matching the versions of Noir. However, to avoid unnecessary build time and size to the existent documentation, they aren't currently released alongside the stable releases, and instead are released ad-hoc.
+
+Please contact any member of the DevRel[^1] team if you believe a new docs version should be cut.
+
+### Cutting a new version of the docs
+
+The Noir documentation is versioned according to the [Docusaurus documentation](https://docusaurus.io/docs/versioning). In the `versioned_docs` and `versioned_sidebar` folders you will find the docs and configs for the previous versions. If any change needs to be made to older versions, please do them in this folder.
+
+In the docs folder, you'll find the current, unreleased version, which we call `dev`. Any change in this folder will be reflected in the next release of the documentation.
+
+While the versioning is intended to be managed by the core maintainers, we feel it's important for external contributors to understand why and how is it maintained. To bump to a new version, run the following command, replacing with the intended version:
+
+```bash
+npm run docusaurus docs:version <new_version_tag>
+```
+
+This should create a new version by copying the docs folder and the sidebars.js file to the relevant folders, as well as adding this version to versions.json.
+
+You can then open a Pull Request according to the the [PR section](#pull-requests)
+

+## Main function
+
+If you're writing a binary, the `main` function is the starting point of your program. You can pass all types of expressions to it, as long as they have a fixed size at compile time:
+
+```rust
+fn main(x : Field) // this is fine: passing a Field
+fn main(x : [Field; 2]) // this is also fine: passing a Field with known size at compile-time
+fn main(x : (Field, bool)) // 👌: passing a (Field, bool) tuple means size 2
+fn main(x : str<5>) // this is fine, as long as you pass a string of size 5
+
+fn main(x : Vec<Field>) // can't compile, has variable size
+fn main(x : [Field]) // can't compile, has variable size
+fn main(....// i think you got it by now
+```
+
+Keep in mind [tests](../nargo/02_testing.md) don't differentiate between `main` and any other function. The following snippet passes tests, but won't compile or prove:

+```rust
+fn main(x : [Field]) {
