### Hardware Requirements <a href="#hardware-requirements" id="hardware-requirements"></a>

1. At least **8GB of RAM** to run efficiently. If you are installing an instance for a large teams or Enterprise, do consider the additional recommendations of **16GB of RAM**.
2. **2 CPU cores** (equivalent to AWS t2.large)
3. **100GB** of disk space.
4. CodeScan must be installed on hard drives that have excellent read & write performance.

{% hint style="info" %}
**Note:** Depending on your use case, this may be way too much or too little. As SonarQube™ stores all snapshots for a long time, the data can build up for a large project. Additionally, heavy usage for users would cause more load.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://knowledgebase.autorabit.com/product-guides/codescan/system-requirements-and-installation.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
