+# 🙌 The OpenHands Community
+
+The OpenHands community is built around the belief that (1) AI and AI agents are going to fundamentally change the way
+we build software, and (2) if this is true, we should do everything we can to make sure that the benefits provided by
+such powerful technology are accessible to everyone.
+
+If this resonates with you, we'd love to have you join us in our quest!
+
+## 🤝 How to Join
+
+Check out our [How to Join the Community section.](https://github.com/All-Hands-AI/OpenHands?tab=readme-ov-file#-how-to-join-the-community)
+
+## 💪 Becoming a Contributor
+
+We welcome contributions from everyone! Whether you're a developer, a researcher, or simply enthusiastic about advancing
+the field of software engineering with AI, there are many ways to get involved:
+
+- **Code Contributions:** Help us develop new core functionality, improve our agents, improve the frontend and other
+interfaces, or anything else that would help make OpenHands better.
+- **Research and Evaluation:** Contribute to our understanding of LLMs in software engineering, participate in
+evaluating the models, or suggest improvements.
+- **Feedback and Testing:** Use the OpenHands toolset, report bugs, suggest features, or provide feedback on usability.
+
+For details, please check [CONTRIBUTING.md](./CONTRIBUTING.md).
+
+## Code of Conduct
+
+We have a [Code of Conduct](./CODE_OF_CONDUCT.md) that we expect all contributors to adhere to.
+Long story short, we are aiming for an open, welcoming, diverse, inclusive, and healthy community.
+All contributors are expected to contribute to building this sort of community.
+
+## 🛠️ Becoming a Maintainer
+
+For contributors who have made significant and sustained contributions to the project, there is a possibility of joining
+the maintainer team. The process for this is as follows:
+
+1. Any contributor who has made sustained and high-quality contributions to the codebase can be nominated by any
+maintainer. If you feel that you may qualify you can reach out to any of the maintainers that have reviewed your PRs and ask if you can be nominated.
+2. Once a maintainer nominates a new maintainer, there will be a discussion period among the maintainers for at least 3 days.
+3. If no concerns are raised the nomination will be accepted by acclamation, and if concerns are raised there will be a discussion and possible vote.
+
+Note that just making many PRs does not immediately imply that you will become a maintainer. We will be looking
+at sustained high-quality contributions over a period of time, as well as good teamwork and adherence to our [Code of Conduct](./CODE_OF_CONDUCT.md).

+## How to Make Effective Contributions
+
+### Opening Issues
+
+If you notice any bugs or have any feature requests please open them via the [issues page](https://github.com/All-Hands-AI/OpenHands/issues). We will triage based on how critical the bug is or how potentially useful the improvement is, discuss, and implement the ones that the community has interest/effort for.
+
+Further, if you see an issue you like, please leave a "thumbs-up" or a comment, which will help us prioritize.
+
+### Making Pull Requests
+
+We're generally happy to consider all PRs, with the evaluation process varying based on the type of change:
+
+#### For Small Improvements
+
+Small improvements with few downsides are typically reviewed and approved quickly.
+One thing to check when making changes is to ensure that all continuous integration tests pass, which you can check before getting a review.
+
+#### For Core Agent Changes
+
+We need to be more careful with changes to the core agent, as it is imperative to maintain high quality. These PRs are evaluated based on three key metrics:
+
+1. **Accuracy**
+2. **Efficiency**
+3. **Code Complexity**
+
+If it improves accuracy, efficiency, or both with only a minimal change to code quality, that's great we're happy to merge it in!
+If there are bigger tradeoffs (e.g. helping efficiency a lot and hurting accuracy a little) we might want to put it behind a feature flag.
+Either way, please feel free to discuss on github issues or slack, and we will give guidance and preliminary feedback.

 ## Technical Explanation
 
 Please refer to [custom docker image section of the runtime documentation](https://docs.all-hands.dev/modules/usage/architecture/runtime#advanced-how-openhands-builds-and-maintains-od-runtime-images) for more details.
-
-## Troubleshooting / Errors
-
-### Error: ```useradd: UID 1000 is not unique```
-
-If you see this error in the console output it is because OpenHands is trying to create the openhands user in the sandbox with a UID of 1000, however this UID is already being used in the image (for some reason). To fix this change the sandbox_user_id field in the config.toml file to a different value:
-
-```toml
-[core]
-workspace_base="./workspace"
-run_as_openhands=true
-sandbox_base_container_image="custom_image"
-sandbox_user_id="1001"
-```
-
-### Port use errors
-
-If you see an error about a port being in use or unavailable, try deleting all running Docker Containers (run `docker ps` and `docker rm` relevant containers) and then re-running ```make run``` .

 ## Installing the Action in a New Repository
 
-To install the OpenHands GitHub Action in your own repository, follow the [directions in the OpenHands Resolver repo](https://github.com/All-Hands-AI/OpenHands-resolver?tab=readme-ov-file#using-the-github-actions-workflow).
+To install the OpenHands GitHub Action in your own repository, follow
+the [README for the OpenHands Resolver](https://github.com/All-Hands-AI/OpenHands/blob/main/openhands/resolver/README.md).
+
+## Usage Tips
+
+### Iterative resolution
+
+1. Create an issue in the repository.
+2. Add the `fix-me` label to the issue, or leave a comment starting with `@openhands-agent`
+3. Review the attempt to resolve the issue by checking the pull request
+4. Follow up with feedback through general comments, review comments, or inline thread comments
+5. Add the `fix-me` label to the pull request, or address a specific comment by starting with `@openhands-agent`
+
+### Label versus Macro
+
+- Label (`fix-me`): Requests OpenHands to address the **entire** issue or pull request.
+- Macro (`@openhands-agent`): Requests OpenHands to consider only the issue/pull request description and **the specific comment**.
+
+## Advanced Settings
+
+### Add custom repository settings
+
+You can provide custom directions for OpenHands by following the [README for the resolver](https://github.com/All-Hands-AI/OpenHands/blob/main/openhands/resolver/README.md#providing-custom-instructions).
+
+### Configure custom macro
+
+To customize the default macro (`@openhands-agent`):
+
+1. [Create a repository variable](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/store-information-in-variables#creating-configuration-variables-for-a-repository) named `OPENHANDS_MACRO`

 ![image](https://github.com/All-Hands-AI/OpenHands/assets/38853559/92b622e3-72ad-4a61-8f41-8c040b6d5fb3)
+
+## Adding New Tools
+
+The CodeAct agent uses a function calling interface to define tools that the agent can use. Tools are defined in `function_calling.py` using the `ChatCompletionToolParam` class from `litellm`. Each tool consists of:
+
+1. A description string that explains what the tool does and how to use it
+2. A tool definition using `ChatCompletionToolParam` that specifies:
+   - The tool's name
+   - The tool's parameters and their types
+   - Required vs optional parameters
+
+Here's an example of how a tool is defined:
+
+```python
+MyTool = ChatCompletionToolParam(
+    type='function',
+    function=ChatCompletionToolParamFunctionChunk(
+        name='my_tool',
+        description='Description of what the tool does and how to use it',
+        parameters={
+            'type': 'object',
+            'properties': {
+                'param1': {
+                    'type': 'string',
+                    'description': 'Description of parameter 1',
+                },
+                'param2': {
+                    'type': 'integer',
+                    'description': 'Description of parameter 2',
+                },
+            },
+            'required': ['param1'],  # List required parameters here
+        },
+    ),
+)
+```
+
+To add a new tool:
+
+1. Define your tool in `function_calling.py` following the pattern above
+2. Add your tool to the `get_tools()` function in `function_calling.py`
+3. Implement the corresponding action handler in the agent to process the tool's invocation
+
+The agent currently supports several built-in tools:
+- `execute_bash`: Execute bash commands
+- `execute_ipython_cell`: Run Python code in IPython
+- `browser`: Interact with a web browser
+- `str_replace_editor`: Edit files using string replacement
+- `edit_file`: Edit files using LLM-based editing
+
+Tools can be enabled/disabled through configuration parameters:
+- `codeact_enable_browsing`: Enable browser interaction
+- `codeact_enable_jupyter`: Enable IPython code execution
+- `codeact_enable_llm_editor`: Enable LLM-based file editing (if disabled, uses string replacement editor instead)
