+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents

+          notices within Derivative Works that You distribute, alongside

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+## Description
+
+`aiac` is a command line tool to generate IaC (Infrastructure as Code) templates
+via [OpenAI](https://openai.com/)'s [ChatGPT](https://chat.openai.com/). The CLI allows you to ask ChatGPT to generate templates
+for different scenarios (e.g. "generate terraform for AWS EC2"). It then makes
+the request on your behalf, accepts the response, and extracts the example code
+from it. This extracted code is either printed to standard output, or saved to a
+file. Optionally, the CLI will append the complete message (i.e. the full
+Markdown response including ChatGPT's explanations) to a separate markdown file.
+
+## Caveats
+
+- ChatGPT's API is not public, and is likely to change frequently, which
+  may break this program. Please inform us via the [issues page](https://github.com/gofireflyio/aiac/issues) if this happens.
+- ChatGPT may rate limit your requests, and is prone to answer slowly or not at
+  all when under heavy load.
+- ChatGPT's responses to the same prompt may differ between executions. If you
+  are unhappy with the results, try again or modify your prompt.
+- You will currently have to manually copy a session token from an actual browser
+  session. Directions in the [Quick Start](#quick-start) section.
+
+## Quick Start
+
+First, install `aiac`:
+
+    go get github.com/gofireflyio/aiac
+
+Alternatively, clone the repository and build from source:
+
+    git clone https://github.com/gofireflyio/aiac.git
+    go build
+
+You will need to provide `aiac` with a session token. Since ChatGPT doesn't
+currently support programmatic usage, you will need to do this via your browser
+(this is hopefully temporary until we can implement OpenAI authentication).
+To get a token, follow these steps:
+
+1. Login to [ChatGPT](https://chat.openai.com/) via your web browser.
+2. Open the Web Developer Tools (usually Ctrl+Shift+I).
+3. Go to the "Storage" tab, and move to the list of "Cookies".
+4. Find the cookie called "__Secure-next-auth.session-token".
+5. Copy its value. This is the session token.
+
+![](/authentication.jpg)
+
+By default, `aiac` simply prints the extracted code to standard output
+
+    aiac --session-token=TOKEN generate terraform for AWS EC2
+
+To store the resulting code to a file, and to append the explanations to a
+markdown file, run:
+
+    aiac --session-token=TOKEN \
+         --output-file="aws_ec2.tf" \
+         --readme-file="README.md" \
+         generate terraform for AWS EC2
+
+## Example Prompts
+
+The following prompts are known to work:
+
+- generate Terraform for AWS EC2
+- generate Dockerfile for NodeJS
+- generate GitHub action for deploying Terraform
+- generate Python code for Pulumi that deploys Azure VPC
+
+## Example Output
+
+Command line prompt:
+
+```sh
+aiac --session-token=TOKEN generate Dockerfile for NodeJS
+```
+
+Output:
+
+```Dockerfile
+FROM node:latest
+
+# Create app directory
+WORKDIR /usr/src/app
+
+# Install app dependencies
+# A wildcard is used to ensure both package.json AND package-lock.json are copied
+# where available (npm@5+)
+COPY package*.json ./
+
+RUN npm install
+# If you are building your code for production
+# RUN npm ci --only=production
+
+# Bundle app source
+COPY . .
+
+EXPOSE 8080
+CMD [ "node", "index.js" ]
+```
