+# GitHub Comment Commands
+
+MyCoder provides automated actions in response to `/mycoder` commands in GitHub issue comments. This feature allows you to trigger MyCoder directly from GitHub issues with flexible prompts.
+
+## How to Use
+
+Simply add a comment to any GitHub issue with `/mycoder` followed by your instructions:
+
+```
+/mycoder [your instructions here]
+```
+
+MyCoder will process your instructions in the context of the issue and respond accordingly.
+
+## Examples
+
+### Creating a PR
+
+```
+/mycoder implement a PR for this issue
+```
+
+MyCoder will:
+1. Check out the repository
+2. Review the issue details
+3. Implement a solution according to the requirements
+4. Create a pull request that addresses the issue
+
+### Creating an Implementation Plan
+
+```
+/mycoder create an implementation plan for this issue
+```
+
+MyCoder will:
+1. Review the issue details
+2. Create a comprehensive implementation plan
+3. Post the plan as a comment on the issue
+
+### Other Use Cases
+
+The `/mycoder` command is flexible and can handle various requests:
+
+```
+/mycoder suggest test cases for this feature
+```
+
+```
+/mycoder analyze the performance implications of this change
+```
+
+```
+/mycoder recommend libraries we could use for this implementation
+```
+
+## How It Works
+
+This functionality is implemented as a GitHub Action that runs whenever a new comment is added to an issue. The action checks for the `/mycoder` command pattern and triggers MyCoder with the appropriate instructions.
+
+MyCoder receives context about:
+- The issue number
+- The specific prompt you provided
+- The comment URL where the command was triggered
+
+If MyCoder creates a PR or takes actions outside the scope of the issue, it will report back to the issue with a comment explaining what was done.
+
+## Requirements
+
+For this feature to work in your repository:
+
+1. The GitHub Action workflow must be present in your repository
+2. You need to configure the necessary API keys as GitHub secrets:
+   - `GITHUB_TOKEN` (automatically provided)
+   - `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, `XAI_API_KEY`, or `MISTRAL_API_KEY` (depending on your preferred model)
+
+## Limitations
+
+- The action runs with GitHub's default timeout limits
+- Complex implementations may require multiple iterations
+- The AI model's capabilities determine the quality of the results
