-     and in which the Licensed Material is translated, altered,
-     arranged, transformed, or otherwise modified in a manner requiring
-     permission under the Copyright and Similar Rights held by the
-     Licensor. For purposes of this Public License, where the Licensed

-     Rights.
-
-  d. Effective Technological Measures means those measures that, in the
-     absence of proper authority, may not be circumvented under laws
-     fulfilling obligations under Article 11 of the WIPO Copyright

-     agreements.
-
-  e. Exceptions and Limitations means fair use, fair dealing, and/or
-     any other exception or limitation to Copyright and Similar Rights
-     that applies to Your use of the Licensed Material.

-     Licensed Material and that the Licensor has authority to license.
-
-  h. Licensor means the individual(s) or entity(ies) granting rights
-     under this Public License.
-
-  i. Share means to provide material to the public by any means or
-     process that requires permission under the Licensed Rights, such

-     resulting from Directive 96/9/EC of the European Parliament and of
-     the Council of 11 March 1996 on the legal protection of databases,
-     as amended and/or succeeded, as well as other essentially
-     equivalent rights anywhere in the world.
-
-  k. You means the individual or entity exercising the Licensed Rights
-     under this Public License. Your has a corresponding meaning.
-
-
-Section 2 -- Scope.
-
-  a. License grant.
-
-       1. Subject to the terms and conditions of this Public License,
-          the Licensor hereby grants You a worldwide, royalty-free,
-          non-sublicensable, non-exclusive, irrevocable license to
-          exercise the Licensed Rights in the Licensed Material to:
-
-            a. reproduce and Share the Licensed Material, in whole or
-               in part; and
-
-            b. produce, reproduce, and Share Adapted Material.
-
-       2. Exceptions and Limitations. For the avoidance of doubt, where
-          Exceptions and Limitations apply to Your use, this Public
-          License does not apply, and You do not need to comply with
-          its terms and conditions.
-
-       3. Term. The term of this Public License is specified in Section
-          6(a).
-
-       4. Media and formats; technical modifications allowed. The
-          Licensor authorizes You to exercise the Licensed Rights in
-          all media and formats whether now known or hereafter created,
-          and to make technical modifications necessary to do so. The
-          Licensor waives and/or agrees not to assert any right or
-          authority to forbid You from making technical modifications
-          necessary to exercise the Licensed Rights, including
-          technical modifications necessary to circumvent Effective
-          Technological Measures. For purposes of this Public License,
-          simply making modifications authorized by this Section 2(a)
-          (4) never produces Adapted Material.
-
-       5. Downstream recipients.
-
-            a. Offer from the Licensor -- Licensed Material. Every
-               recipient of the Licensed Material automatically
-               receives an offer from the Licensor to exercise the
-               Licensed Rights under the terms and conditions of this
-               Public License.
-
-            b. No downstream restrictions. You may not offer or impose
-               any additional or different terms or conditions on, or
-               apply any Effective Technological Measures to, the
-               Licensed Material if doing so restricts exercise of the
-               Licensed Rights by any recipient of the Licensed
-               Material.
-
-       6. No endorsement. Nothing in this Public License constitutes or
-          may be construed as permission to assert or imply that You
-          are, or that Your use of the Licensed Material is, connected
-          with, or sponsored, endorsed, or granted official status by,
-          the Licensor or others designated to receive attribution as
-          provided in Section 3(a)(1)(A)(i).
-
-  b. Other rights.
-
-       1. Moral rights, such as the right of integrity, are not
-          licensed under this Public License, nor are publicity,
-          privacy, and/or other similar personality rights; however, to
-          the extent possible, the Licensor waives and/or agrees not to
-          assert any such rights held by the Licensor to the limited
-          extent necessary to allow You to exercise the Licensed
-          Rights, but not otherwise.
-
-       2. Patent and trademark rights are not licensed under this
-          Public License.
-
-       3. To the extent possible, the Licensor waives any right to
-          collect royalties from You for the exercise of the Licensed
-          Rights, whether directly or through a collecting society
-          under any voluntary or waivable statutory or compulsory
-          licensing scheme. In all other cases the Licensor expressly
-          reserves any right to collect such royalties.
-
-
-Section 3 -- License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
-  a. Attribution.
-
-       1. If You Share the Licensed Material (including in modified
-          form), You must:
-
-            a. retain the following if it is supplied by the Licensor
-               with the Licensed Material:
-
-                 i. identification of the creator(s) of the Licensed
-                    Material and any others designated to receive
-                    attribution, in any reasonable manner requested by
-                    the Licensor (including by pseudonym if
-                    designated);
-
-                ii. a copyright notice;
-
-               iii. a notice that refers to this Public License;
-
-                iv. a notice that refers to the disclaimer of
-                    warranties;
-
-                 v. a URI or hyperlink to the Licensed Material to the
-                    extent reasonably practicable;
-
-            b. indicate if You modified the Licensed Material and
-               retain an indication of any previous modifications; and
-
-            c. indicate the Licensed Material is licensed under this
-               Public License, and include the text of, or the URI or
-               hyperlink to, this Public License.
-
-       2. You may satisfy the conditions in Section 3(a)(1) in any
-          reasonable manner based on the medium, means, and context in
-          which You Share the Licensed Material. For example, it may be
-          reasonable to satisfy the conditions by providing a URI or
-          hyperlink to a resource that includes the required
-          information.
-
-       3. If requested by the Licensor, You must remove any of the
-          information required by Section 3(a)(1)(A) to the extent
-          reasonably practicable.
-
-       4. If You Share Adapted Material You produce, the Adapter's
-          License You apply must not prevent recipients of the Adapted
-          Material from complying with this Public License.
-
-
-Section 4 -- Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that
-apply to Your use of the Licensed Material:
-
-  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
-     to extract, reuse, reproduce, and Share all or a substantial
-     portion of the contents of the database;
-
-  b. if You include all or a substantial portion of the database
-     contents in a database in which You have Sui Generis Database
-     Rights, then the database in which You have Sui Generis Database
-     Rights (but not its individual contents) is Adapted Material; and
-
-  c. You must comply with the conditions in Section 3(a) if You Share
-     all or a substantial portion of the contents of the database.
-
-For the avoidance of doubt, this Section 4 supplements and does not
-replace Your obligations under this Public License where the Licensed
-Rights include other Copyright and Similar Rights.
-
-
-Section 5 -- Disclaimer of Warranties and Limitation of Liability.
-
-  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
-     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
-     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
-     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
-     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
-     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
-     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
-     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
-     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
-     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
-
-  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
-     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
-     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
-     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
-     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
-     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
-     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
-     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
-     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
-
-  c. The disclaimer of warranties and limitation of liability provided
-     above shall be interpreted in a manner that, to the extent
-     possible, most closely approximates an absolute disclaimer and
-     waiver of all liability.
-
-
-Section 6 -- Term and Termination.
-
-  a. This Public License applies for the term of the Copyright and
-     Similar Rights licensed here. However, if You fail to comply with
-     this Public License, then Your rights under this Public License
-     terminate automatically.
-
-  b. Where Your right to use the Licensed Material has terminated under
-     Section 6(a), it reinstates:
-
-       1. automatically as of the date the violation is cured, provided
-          it is cured within 30 days of Your discovery of the
-          violation; or
-
-       2. upon express reinstatement by the Licensor.
-
-     For the avoidance of doubt, this Section 6(b) does not affect any
-     right the Licensor may have to seek remedies for Your violations
-     of this Public License.
-
-  c. For the avoidance of doubt, the Licensor may also offer the
-     Licensed Material under separate terms or conditions or stop
-     distributing the Licensed Material at any time; however, doing so
-     will not terminate this Public License.
-
-  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
-     License.
-
-
-Section 7 -- Other Terms and Conditions.
-
-  a. The Licensor shall not be bound by any additional or different
-     terms or conditions communicated by You unless expressly agreed.
-
-  b. Any arrangements, understandings, or agreements regarding the
-     Licensed Material not stated herein are separate from and
-     independent of the terms and conditions of this Public License.
-
-
-Section 8 -- Interpretation.
-
-  a. For the avoidance of doubt, this Public License does not, and
-     shall not be interpreted to, reduce, limit, restrict, or impose
-     conditions on any use of the Licensed Material that could lawfully
-     be made without permission under this Public License.
-
-  b. To the extent possible, if any provision of this Public License is
-     deemed unenforceable, it shall be automatically reformed to the
-     minimum extent necessary to make it enforceable. If the provision
-     cannot be reformed, it shall be severed from this Public License
-     without affecting the enforceability of the remaining terms and
-     conditions.
-
-  c. No term or condition of this Public License will be waived and no
-     failure to comply consented to unless expressly agreed to by the
-     Licensor.
-
-  d. Nothing in this Public License constitutes or may be interpreted
-     as a limitation upon, or waiver of, any privileges and immunities
-     that apply to the Licensor or You, including from the legal
-     processes of any jurisdiction or authority.

+# React Native Technical Documentation Guidelines
+
+_This is a document about documentation (hence the file name)._
+
+## Motivation
+
+The goals of this documentation are:
+
+1. To make it easier for people to understand and contribute to the React Native
+   architecture.
+2. To ensure the architecture is easy to maintain, with clearly scoped
+   subsystems that are easy to reason about and change.
+
+## Strategy
+
+Our documentation supports the following use cases:
+
+1. (Exploration based) I want to understand how React Native works and learn
+   about its different parts. I want to explore.
+2. (Goal based) I want to solve a problem and change something specific, so I
+   want to understand what I should change and how the system I need to change
+   works. I need to understand how other systems depend on this.
+
+To support the first case, we provide a single entrypoint for the whole
+documentation, which will be the first step in a tree of docs with links to
+parents and children:
+
+- `<root>/__docs__/README.md` (with links to subsystems 1, 2, etc.)
+  - `Subsystem 1/__docs__/README.md` (with links to root and subsystems 1.1,
+    1.2, etc.)
+    - `Subsystem 1.1/__docs__/README.md` (with links to subsystem 1 and
+      subsystems 1.1.1, 1.1.2, etc.)
+    - `Subsystem 1.2/__docs__/README.md`
+  - `Subsystem 2/__docs__/README.md`
+
+This structure will make it possible for the user to navigate across the
+documentation organically, just following links within the documents themselves.
+
+To support the second use case, focusing on a specific subsystem, we will
+describe what are the relationships between that subsystem and others, to make
+sure that changes to its API are understood, and that usages of other subsystems
+are considered.
+
+The use of the `__docs__` directory (inspired by Python) has 2 goals:
+
+1. Make the documentation easy to find in the directory, by generally appearing
+   at the top of the directory (similar to `__tests__`).
+2. Grouping the documentation itself and its assets (images, diagrams, etc.).
+
+## Guidelines
+
+### Content
+
+Use [this template](./README-template.md) to write the documentation for a
+subsystem, adding the appropriate subsections depending on what that
+documentation requires. Only diverge from this structure if it is strictly
+necessary (removing unnecessary or empty sections is fine).
+
+Include supporting images and diagrams in the documentation. Those assets should
+be placed in the same `__docs__` directory as the `README.md` file. Use relative
+paths to link to the assets in those directories.
+
+If you include Excalidraw diagrams, make sure to export an SVG image from the
+website using the "Embedded scene" option, so the original diagram is included
+in the file and can be re-uploaded to Excalidraw for future modifications. Use
+the extension `.excalidraw.svg` to signal this.
+
+### Granularity
+
+The level of granularity in the definition of the subsystems should be enough to
+correctly describe how React Native works, but not so detailed that any changes
+in the code require changes in the documentation.
+
+Examples:
+
+- Requires updating the docs:
+  - Adding a new major feature or API.
+  - Adding a new relevant dependency. Adding a dependency to helper functions
+    does not count as relevant.
+- Does NOT require updating the docs:
+  - Internal implementation details that do not change how the system works or
+    interacts with others.
+  - Making a minor API or feature change.
+  - Internal refactors, even if they create new modules or introduce
+    dependencies to external helpers.
+
+### Location
+
+When a specific subsystem exists in multiple directories (e.g.:
+platform-specific ones, C++, JavaScript, etc.):

+# React Native Technical Documentation
+
+The React Native technical documentation describes how React Native works
+internally, the subsystems it is composed of, how they work and how they
+interact with each other.
+
+The intended audience is people who want to learn about the internals of React
+Native and contribute to it. **End users of React Native are meant to use the
+[public website](https://reactnative.dev) instead** (its code can be found
+[here](https://github.com/facebook/react-native-website)).
+
+For details on how we approach technical documentation in this repository, see
+[GUIDELINES.md](./GUIDELINES.md).
+
+## 🚀 Usage
+
+This repository is not meant to be consumed directly by end users. Instead, it
+creates several packages that are published to the NPM registry for direct
+consumption by end users and frameworks.
+
+This repository uses a monorepo approach, and public packages can be found in
+the [`packages`](../packages/) directory (the ones that do not contain
+`"private": true` in their `package.json` file).
+
+The most important package is the
+[`react-native`](https://www.npmjs.com/package/react-native) package, located in
+[`packages/react-native`](../packages/react-native), which contains the public
+JavaScript API.
+
+This repository provides the Android and iOS versions of React Native. Versions
+for other platforms are maintained in their own repositories.
+
+## 📐 Design
+
+TODO: Explain the different components of React Native at a high level.
+
+## 🔗 Relationship with other systems

+### Used by this
+
+This repository has many different types of dependencies: build systems,
+external packages to be used during development, external packages used at
+runtime, etc.
+
+### Uses this
+
+The main use cases for this repository are:
+
+1. Developing React Native itself.
+2. Testing and releasing React Native.
+3. Synchronizing forks like `react-native-windows` and `react-native-macos`.
