 ## Architecture Decision Records (ADR)
 
-When proposing an architecture decision for Ethermint, please start by opening an [issue](https://github.com/evmos/ethermint/issues/new/choose) or a [discussion](https://github.com/evmos/ethermint/discussions/new) with a summary of the proposal. Once the proposal has been discussed and there is rough alignment on a high-level approach to the design, the [ADR creation process](https://github.com/evmos/ethermint/blob/main/docs/architecture/PROCESS.md) can begin. We are following this process to ensure all involved parties are in agreement before any party begins coding the proposed implementation. If you would like to see examples of how these are written, please refer to the current [ADRs](https://github.com/evmos/ethermint/tree/main/docs/architecture).

Once the proposal has been discussed and there is rough alignment on a high-level approach to the design, the [ADR creation process](https://github.com/tharsis/ethermint/blob/main/docs/architecture/PROCESS.md) can begin. We are following this process to ensure all involved parties are in agreement before any party begins coding the proposed implementation. If you would like to see examples of how these are written, please refer to the current [ADRs](https://github.com/tharsis/ethermint/tree/main/docs/architecture).

+### Updating Documentation
+
+If you open a PR on Ethermint, it is mandatory to update the relevant documentation in `/docs`.
+
+- If your change relates to the core SDK (baseapp, store, ...), be sure to update the content in `docs/basics/`, `docs/core/` and/or `docs/building-modules/` folders.
+- If your changes relate to the core of the CLI (not specifically to module's CLI/Rest), then modify the content in the `docs/run-node/` folder.
+- If your changes relate to a module, then be sure to update the module's spec in `x/moduleName/docs/spec/`.
+
+When writing documentation, follow the [Documentation Writing Guidelines](./docs/DOC_WRITING_GUIDELINES.md).

 ## Forking
 
 Go requires code to live under absolute paths, and this requirement complicates forking.
 While my fork lives at `https://github.com/rigeyrigerige/ethermint`,
 the code should never exist at `$GOPATH/src/github.com/rigeyrigerige/ethermint`.
 Instead, we use `git remote` to add the fork as a new remote for the original repo,

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
 
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the

+      of your accepting any such warranty or additional liability.

+   END OF TERMS AND CONDITIONS
 
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
+   APPENDIX: How to apply the Apache License to your work.
 
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.
 
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
+   Copyright [yyyy] [name of copyright owner]
 
-  5. Combined Libraries.
+   Licensed under the Apache License, Version 2.0 (the "License");
+   you may not use this file except in compliance with the License.
+   You may obtain a copy of the License at
 
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
+       http://www.apache.org/licenses/LICENSE-2.0
 
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-The Source of Proof. Laconic is a next generation data availability & verifiability layer with cryptographic proofs, powering internet-scale Web3 applications, built on Proof-of-Stake with fast-finality using the [Cosmos SDK](https://github.com/cosmos/cosmos-sdk/) which runs on top of [Tendermint Core](https://github.com/tendermint/tendermint) consensus engine.
+Ethermint is a scalable, high-throughput Proof-of-Stake blockchain that is fully compatible and
+interoperable with Ethereum. It's build using the the [Cosmos SDK](https://github.com/cosmos/cosmos-sdk/) which runs on top of [Tendermint Core](https://github.com/tendermint/tendermint) consensus engine.
 
-**Note**: Requires [Go 1.19+](https://golang.org/dl/)
+**Note**: Requires [Go 1.17+](https://golang.org/dl/)
 
 ## Installation
 
+For prerequisites and detailed build instructions please read the [Installation](https://ethermint.dev/quickstart/installation.html) instructions. Once the dependencies are installed, run:
+
 ```bash
 make install
 ```
 
-## Usage
+Or check out the latest [release](https://github.com/tharsis/ethermint/releases).
 
-To quickly get started with a single node fixture, run:
+## Quick Start
 
-```bash
-./init.sh
-```
+To learn how the Ethermint works from a high-level perspective, go to the [Introduction](https://ethermint.dev/intro/overview.html) section from the documentation. You can also check the instructions to [Run a Node](https://ethermint.dev/quickstart/run_node.html).
