+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.

+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+# RISC Zero Rust Starter Template
+
+Welcome to the RISC Zero Rust Starter Template! This template is intended to
+give you a starting point for building a project using the RISC Zero zkVM.
+Throughout the template (including in this README), you'll find comments
+labelled `TODO` in places where you'll need to make changes. To better
+understand the concepts behind this template, check out the [zkVM
+Overview][zkvm-overview].
+
+## Quick Start
+
+First, make sure [rustup] is installed. The
+[`rust-toolchain.toml`][rust-toolchain] file will be used by `cargo` to
+automatically install the correct version.
+
+To build all methods and execute the method within the zkVM, run the following
+command:
+
+```bash
+cargo run
+```
+
+This is an empty template, and so there is no expected output (until you modify
+the code).
+
+### Executing the Project Locally in Development Mode
+
+During development, faster iteration upon code changes can be achieved by leveraging [dev-mode], we strongly suggest activating it during your early development phase. Furthermore, you might want to get insights into the execution statistics of your project, and this can be achieved by specifying the environment variable `RUST_LOG="[executor]=info"` before running your project.
+
+Put together, the command to run your project in development mode while getting execution statistics is:
+
+```bash
+RUST_LOG="[executor]=info" RISC0_DEV_MODE=1 cargo run
+```
+
+### Running Proofs Remotely on Bonsai
+
+_Note: The Bonsai proving service is still in early Alpha; an API key is
+required for access. [Click here to request access][bonsai access]._
+
+If you have access to the URL and API key to Bonsai you can run your proofs
+remotely. To prove in Bonsai mode, invoke `cargo run` with two additional
+environment variables:
+
+```bash
+BONSAI_API_KEY="YOUR_API_KEY" BONSAI_API_URL="BONSAI_URL" cargo run
+```
+
+## How to Create a Project Based on This Template
+
+Search this template for the string `TODO`, and make the necessary changes to
+implement the required feature described by the `TODO` comment. Some of these
+changes will be complex, and so we have a number of instructional resources to
+assist you in learning how to write your own code for the RISC Zero zkVM:
+
+- The [RISC Zero Developer Docs][dev-docs] is a great place to get started.
+- Example projects are available in the [examples folder][examples] of
+  [`risc0`][risc0-repo] repository.
+- Reference documentation is available at [https://docs.rs][docs.rs], including
+  [`risc0-zkvm`][risc0-zkvm], [`cargo-risczero`][cargo-risczero],
+  [`risc0-build`][risc0-build], and [others][crates].
+
+## Directory Structure
+
+It is possible to organize the files for these components in various ways.
+However, in this starter template we use a standard directory structure for zkVM
+applications, which we think is a good starting point for your applications.
+
+```text
+project_name
+├── Cargo.toml
+├── host
+│   ├── Cargo.toml
+│   └── src
+│       └── main.rs                    <-- [Host code goes here]
+└── methods
+    ├── Cargo.toml
+    ├── build.rs
+    ├── guest
+    │   ├── Cargo.toml
+    │   └── src
+    │       └── method_name.rs         <-- [Guest code goes here]
+    └── src
+        └── lib.rs
+```
+

+For a walk-through of how to build with this template, check out this [excerpt
+from our workshop at ZK HACK III][zkhack-iii].
