+Following are the parameters supported by Ollama:
+
+| Parameter      | Description                                                                                                                                                                                                                                             | Value Type | Example Usage        |
+|----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------|----------------------|
+| mirostat       | Enable Mirostat sampling for controlling perplexity. (default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0)                                                                                                                                         | int        | mirostat 0           |
+| mirostat_eta   | Influences how quickly the algorithm responds to feedback from the generated text. A lower learning rate will result in slower adjustments, while a higher learning rate will make the algorithm more responsive. (Default: 0.1)                        | float      | mirostat_eta 0.1     |
+| mirostat_tau   | Controls the balance between coherence and diversity of the output. A lower value will result in more focused and coherent text. (Default: 5.0)                                                                                                         | float      | mirostat_tau 5.0     |
+| num_ctx        | Sets the size of the context window used to generate the next token. (Default: 2048)                                                                                                                                                                    | int        | num_ctx 4096         |
+| num_gqa        | The number of GQA groups in the transformer layer. Required for some models, for example it is 8 for llama2:70b                                                                                                                                         | int        | num_gqa 1            |
+| num_gpu        | The number of layers to send to the GPU(s). On macOS it defaults to 1 to enable metal support, 0 to disable.                                                                                                                                            | int        | num_gpu 50           |
+| num_thread     | Sets the number of threads to use during computation. By default, Ollama will detect this for optimal performance. It is recommended to set this value to the number of physical CPU cores your system has (as opposed to the logical number of cores). | int        | num_thread 8         |
+| repeat_last_n  | Sets how far back for the model to look back to prevent repetition. (Default: 64, 0 = disabled, -1 = num_ctx)                                                                                                                                           | int        | repeat_last_n 64     |
+| repeat_penalty | Sets how strongly to penalize repetitions. A higher value (e.g., 1.5) will penalize repetitions more strongly, while a lower value (e.g., 0.9) will be more lenient. (Default: 1.1)                                                                     | float      | repeat_penalty 1.1   |
+| temperature    | The temperature of the model. Increasing the temperature will make the model answer more creatively. (Default: 0.8)                                                                                                                                     | float      | temperature 0.7      |
+| seed           | Sets the random number seed to use for generation. Setting this to a specific number will make the model generate the same text for the same prompt. (Default: 0)                                                                                       | int        | seed 42              |
+| stop           | Sets the stop sequences to use. When this pattern is encountered the LLM will stop generating text and return. Multiple stop patterns may be set by specifying multiple separate `stop` parameters in a modelfile.                                      | string     | stop "AI assistant:" |
+| tfs_z          | Tail free sampling is used to reduce the impact of less probable tokens from the output. A higher value (e.g., 2.0) will reduce the impact more, while a value of 1.0 disables this setting. (default: 1)                                               | float      | tfs_z 1              |
+| num_predict    | Maximum number of tokens to predict when generating text. (Default: 128, -1 = infinite generation, -2 = fill context)                                                                                                                                   | int        | num_predict 42       |
+| top_k          | Reduces the probability of generating nonsense. A higher value (e.g. 100) will give more diverse answers, while a lower value (e.g. 10) will be more conservative. (Default: 40)                                                                        | int        | top_k 40             |
+| top_p          | Works together with top-k. A higher value (e.g., 0.95) will lead to more diverse text, while a lower value (e.g., 0.5) will generate more focused and conservative text. (Default: 0.9)                                                                 | float      | top_p 0.9            |

+> First Answer: The image shows a dog sitting on the bow of a boat that is docked in calm water. The boat has two levels, with the lower level containing seating and what appears to be an engine cover. The dog seems relaxed and comfortable on the boat, looking out over the water. The background suggests it might be late afternoon or early evening, given the warm lighting and the low position of the sun in the sky.
+>
+> Second Answer: Based on the image, it's difficult to definitively determine the breed of the dog. However, the dog appears to be medium-sized with a short coat and a brown coloration, which might suggest that it is a Golden Retriever or a similar breed. Without more details like ear shape and tail length, it's not possible to identify the exact breed confidently.

+Once created, you can see it when you use [list models](./list-models) API.
+
+### Example of a `Modelfile`
+
+```
+FROM llama2
+# sets the temperature to 1 [higher is more creative, lower is more coherent]
+PARAMETER temperature 1
+# sets the context window size to 4096, this controls how many tokens the LLM can use as context to generate the next token
+PARAMETER num_ctx 4096
+
+# sets a custom system message to specify the behavior of the chat assistant
+SYSTEM You are Mario from super mario bros, acting as an assistant.
+```
+
+### Format of the `Modelfile`
+
+```modelfile
+# comment
+INSTRUCTION arguments
+```
+
+| Instruction                         | Description                                                    |
+|-------------------------------------|----------------------------------------------------------------|

+
+#### PARAMETER
+
+The `PARAMETER` instruction defines a parameter that can be set when the model is run.
+
+| Parameter      | Description                                                                                                                                                                                                                                             | Value Type | Example Usage        |
+|----------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------|----------------------|
+| mirostat       | Enable Mirostat sampling for controlling perplexity. (default: 0, 0 = disabled, 1 = Mirostat, 2 = Mirostat 2.0)                                                                                                                                         | int        | mirostat 0           |
+| mirostat_eta   | Influences how quickly the algorithm responds to feedback from the generated text. A lower learning rate will result in slower adjustments, while a higher learning rate will make the algorithm more responsive. (Default: 0.1)                        | float      | mirostat_eta 0.1     |
+| mirostat_tau   | Controls the balance between coherence and diversity of the output. A lower value will result in more focused and coherent text. (Default: 5.0)                                                                                                         | float      | mirostat_tau 5.0     |
+| num_ctx        | Sets the size of the context window used to generate the next token. (Default: 2048)                                                                                                                                                                    | int        | num_ctx 4096         |
+| num_gqa        | The number of GQA groups in the transformer layer. Required for some models, for example it is 8 for llama2:70b                                                                                                                                         | int        | num_gqa 1            |
+| num_gpu        | The number of layers to send to the GPU(s). On macOS it defaults to 1 to enable metal support, 0 to disable.                                                                                                                                            | int        | num_gpu 50           |
+| num_thread     | Sets the number of threads to use during computation. By default, Ollama will detect this for optimal performance. It is recommended to set this value to the number of physical CPU cores your system has (as opposed to the logical number of cores). | int        | num_thread 8         |
+| repeat_last_n  | Sets how far back for the model to look back to prevent repetition. (Default: 64, 0 = disabled, -1 = num_ctx)                                                                                                                                           | int        | repeat_last_n 64     |
+| repeat_penalty | Sets how strongly to penalize repetitions. A higher value (e.g., 1.5) will penalize repetitions more strongly, while a lower value (e.g., 0.9) will be more lenient. (Default: 1.1)                                                                     | float      | repeat_penalty 1.1   |
+| temperature    | The temperature of the model. Increasing the temperature will make the model answer more creatively. (Default: 0.8)                                                                                                                                     | float      | temperature 0.7      |
+| seed           | Sets the random number seed to use for generation. Setting this to a specific number will make the model generate the same text for the same prompt. (Default: 0)                                                                                       | int        | seed 42              |
+| stop           | Sets the stop sequences to use. When this pattern is encountered the LLM will stop generating text and return. Multiple stop patterns may be set by specifying multiple separate `stop` parameters in a modelfile.                                      | string     | stop "AI assistant:" |
+| tfs_z          | Tail free sampling is used to reduce the impact of less probable tokens from the output. A higher value (e.g., 2.0) will reduce the impact more, while a value of 1.0 disables this setting. (default: 1)                                               | float      | tfs_z 1              |
+| num_predict    | Maximum number of tokens to predict when generating text. (Default: 128, -1 = infinite generation, -2 = fill context)                                                                                                                                   | int        | num_predict 42       |
+| top_k          | Reduces the probability of generating nonsense. A higher value (e.g. 100) will give more diverse answers, while a lower value (e.g. 10) will be more conservative. (Default: 40)                                                                        | int        | top_k 40             |
+| top_p          | Works together with top-k. A higher value (e.g., 0.95) will lead to more diverse text, while a lower value (e.g., 0.5) will generate more focused and conservative text. (Default: 0.9)                                                                 | float      | top_p 0.9            |
+
+#### TEMPLATE
+
+`TEMPLATE` of the full prompt template to be passed into the model. It may include (optionally) a system message and a
+user's prompt. This is used to create a full custom prompt, and syntax may be model specific. You can usually find the
+template for a given model in the readme for that model.
+
+#### Template Variables
+
+| Variable        | Description                                                                                                   |
+|-----------------|---------------------------------------------------------------------------------------------------------------|
+| `{{ .System }}` | The system message used to specify custom behavior, this must also be set in the Modelfile as an instruction. |
+| `{{ .Prompt }}` | The incoming prompt, this is not specified in the model file and will be set based on input.                  |
+| `{{ .First }}`  | A boolean value used to render specific template information for the first generation of a session.           |
+
+```modelfile
+TEMPLATE """
+{{- if .First }}
+### System:
+{{ .System }}
+{{- end }}
+
+### User:
+{{ .Prompt }}
+
+### Response:
+"""
+
+SYSTEM """<system message>"""
+```
+
+### SYSTEM
+
+The `SYSTEM` instruction specifies the system message to be used in the template, if applicable.
+
+```modelfile
+SYSTEM """<system message>"""
+```
+
+### ADAPTER
+
+The `ADAPTER` instruction specifies the LoRA adapter to apply to the base model. The value of this instruction should be
+an absolute path or a path relative to the Modelfile and the file must be in a GGML file format. The adapter should be
+tuned from the base model otherwise the behaviour is undefined.
+
+```modelfile
+ADAPTER ./ollama-lora.bin
+```
+
+### LICENSE
+
+The `LICENSE` instruction allows you to specify the legal license under which the model used with this Modelfile is
+shared or distributed.
+
+```modelfile
+LICENSE """
+<license text>
+"""
+```
+
+## Notes
+
+- the **`Modelfile` is not case sensitive**. In the examples, uppercase instructions are used to make it easier to
+  distinguish it from arguments.
+- Instructions can be in any order. In the examples, the `FROM` instruction is first to keep it easily readable.

-# Tutorial Intro
+# Introduction
 
-Let's discover **Docusaurus in less than 5 minutes**.
+Let's get started with **Ollama4j**.
+
+## 🦙 What is Ollama?
+
+[Ollama](https://ollama.ai/) is an advanced AI tool that allows users to easily set up and run large language models
+locally (in CPU and GPU
+modes). With Ollama, users can leverage powerful language models such as Llama 2 and even customize and create their own
+models.
+
+## 👨‍💻 Why Ollama4j?
+
+Ollama4j was built for the simple purpose of integrating Ollama with Java applications.
+
+```mermaid
+  flowchart LR
+    o4j[Ollama4j]
+    o[Ollama Server]
+    o4j -->|Communicates with| o;
+    m[Models]
+    p[Your Java Project]
+    subgraph Your Java Environment
+        direction TB
+        p -->|Uses| o4j
+    end
+    subgraph Ollama Setup
+        direction TB
+        o -->|Manages| m
+    end
+```
 
 ## Getting Started
 
-Get started by **creating a new site**.
-
-Or **try Docusaurus immediately** with **[docusaurus.new](https://docusaurus.new)**.
-
 ### What you'll need
 
-- [Node.js](https://nodejs.org/en/download/) version 18.0 or above:
-  - When installing Node.js, you are recommended to check all checkboxes related to dependencies.
+- **[Ollama](https://ollama.ai/download)**
+- **[Oracle JDK](https://www.oracle.com/java/technologies/javase/jdk11-archive-downloads.html)** or
+  **[Open JDK](https://jdk.java.net/archive/)** 11.0 or above.
+- **[Maven](https://maven.apache.org/download.cgi)**
 
-## Generate a new site
+### Start Ollama server
 
-Generate a new Docusaurus site using the **classic template**.
+The easiest way of getting started with Ollama server is with [Docker](https://docs.docker.com/get-started/overview/).
+But if you choose to run the
+Ollama server directly, **[download](https://ollama.ai/download)** the distribution of your choice
+and follow the installation process.
 
-The classic template will automatically be added to your project after you run the command:
+#### With Docker
+
+##### Run in CPU mode:
 
 ```bash
-npm init docusaurus@latest my-website classic
+docker run -it -v ~/ollama:/root/.ollama -p 11434:11434 ollama/ollama
 ```
 
-You can type this command into Command Prompt, Powershell, Terminal, or any other integrated terminal of your code editor.
-
-The command also installs all necessary dependencies you need to run Docusaurus.
-
-## Start your site
-
-Run the development server:
+##### Run in GPU mode:
 
 ```bash
-cd my-website
-npm run start
+docker run -it --gpus=all -v ~/ollama:/root/.ollama -p 11434:11434 ollama/ollama
 ```
 
-The `cd` command changes the directory you're working with. In order to work with your newly created Docusaurus site, you'll need to navigate the terminal there.
+You can type this command into Command Prompt, Powershell, Terminal, or any other integrated
+terminal of your code editor.
 
-The `npm run start` command builds your website locally and serves it through a development server, ready for you to view at http://localhost:3000/.
+The command runs the Ollama server locally at **http://localhost:11434/**.
 
-Open `docs/intro.md` (this page) and edit some lines: the site **reloads automatically** and displays your changes.
+### Setup your project
+
+Get started by **creating a new Maven project** on your favorite IDE.
+
+Add the dependency to your project's `pom.xml`.
+
+```xml
+
+<dependency>
+    <groupId>io.github.amithkoujalgi</groupId>
+    <artifactId>ollama4j</artifactId>
+    <version>1.0.27</version>
+</dependency>
+```
+
+Find the latest version of the library [here](https://central.sonatype.com/artifact/io.github.amithkoujalgi/ollama4j).
+
+You might want to include an implementation of [SL4J](https://www.slf4j.org/) logger in your `pom.xml` file. For
+example,
+
+Use `slf4j-jdk14` implementation:
+
+```xml
+
+<dependency>
+    <groupId>org.slf4j</groupId>
+    <artifactId>slf4j-jdk14</artifactId>
+    <version>2.0.9</version> <!--Replace with appropriate version-->
+</dependency>
+```
+
+or use `logback-classic` implementation:
+
+```xml
+
+<dependency>
+    <groupId>ch.qos.logback</groupId>
+    <artifactId>logback-classic</artifactId>
+    <version>1.3.11</version> <!--Replace with appropriate version-->
+</dependency>
+```
+
+or use other suitable implementations.
+
+Create a new Java class in your project and add this code.
+
+```java
+public class OllamaAPITest {
+
+    public static void main(String[] args) {
+        String host = "http://localhost:11434/";
+
+        OllamaAPI ollamaAPI = new OllamaAPI(host);
+
+        ollamaAPI.setVerbose(true);
+
+        boolean isOllamaServerReachable = ollamaAPI.ping();
+
+        System.out.println("Is Ollama server alive: " + isOllamaServerReachable);
+    }
+}
+```

-Documents are **groups of pages** connected through:
-
-- a **sidebar**
-- **previous/next navigation**
-- **versioning**
-
-## Create your first Doc
-
-Create a Markdown file at `docs/hello.md`:

-## Configure the Sidebar
-
-Docusaurus automatically **creates a sidebar** from the `docs` folder.
-
-Add metadata to customize the sidebar label and position:
-
-```md title="docs/hello.md" {1-4}
----
-sidebar_label: 'Hi!'
-sidebar_position: 3
----
-
-# Hello
-
-This is my **first Docusaurus document**!
-```
-
-It is also possible to create your sidebar explicitly in `sidebars.js`:
-
-```js title="sidebars.js"
-export default {
-  tutorialSidebar: [
-    'intro',
-    // highlight-next-line
-    'hello',
-    {

-# Deploy your site
-
-Docusaurus is a **static-site-generator** (also called **[Jamstack](https://jamstack.org/)**).
-
-It builds your site as simple **static HTML, JavaScript and CSS files**.
-
-## Build your site
-
-Build your site **for production**:
-
-```bash
-npm run build
-```
-
-The static files are generated in the `build` folder.
-
-## Deploy your site
-
-Test your production build locally:
-
-```bash
-npm run serve
-```
-
-The `build` folder is now served at [http://localhost:3000/](http://localhost:3000/).
-
-You can now deploy the `build` folder **almost anywhere** easily, **for free** or very small cost (read the **[Deployment Guide](https://docusaurus.io/docs/deployment)**).

-# Markdown Features
-
-Docusaurus supports **[Markdown](https://daringfireball.net/projects/markdown/syntax)** and a few **additional features**.
-
-## Front Matter
-
-Markdown documents have metadata at the top called [Front Matter](https://jekyllrb.com/docs/front-matter/):
-
-```text title="my-doc.md"
-// highlight-start
----
-id: my-doc-id
-title: My document title
-description: My document description
-slug: /my-custom-url
----
-// highlight-end
-
-## Markdown heading
-
-Markdown text with [links](./hello.md)
-```
-
-## Links
-
-Regular Markdown links are supported, using url paths or relative file paths.
-
-```md
-Let's see how to [Create a page](/create-a-page).
-```
-
-```md
-Let's see how to [Create a page](./create-a-page.md).
-```
-
-**Result:** Let's see how to [Create a page](./create-a-page.md).
-
-## Images
-
-Regular Markdown images are supported.
-
-You can use absolute paths to reference images in the static directory (`static/img/docusaurus.png`):
-
-```md
-![Docusaurus logo](/img/docusaurus.png)
-```
-
-![Docusaurus logo](/img/docusaurus.png)
-
-You can reference images relative to the current file as well. This is particularly useful to colocate images close to the Markdown files using them:
-
-```md
-![Docusaurus logo](./img/docusaurus.png)
-```
-
-## Code Blocks
-
-Markdown code blocks are supported with Syntax highlighting.
-
-    ```jsx title="src/components/HelloDocusaurus.js"
-    function HelloDocusaurus() {
-        return (
-            <h1>Hello, Docusaurus!</h1>
-        )
-    }
-    ```
-
-```jsx title="src/components/HelloDocusaurus.js"
-function HelloDocusaurus() {
-  return <h1>Hello, Docusaurus!</h1>;
-}
-```
-
-## Admonitions
-
-Docusaurus has a special syntax to create admonitions and callouts:
-
-    :::tip My tip
-
-    Use this awesome feature option
-
-    :::
-
-    :::danger Take care
-
-    This action is dangerous
-
-    :::
-
-:::tip My tip
-
-Use this awesome feature option
-
-:::
-
-:::danger Take care
-
-This action is dangerous
-
-:::
-
-## MDX and React Components
-
-[MDX](https://mdxjs.com/) can make your documentation more **interactive** and allows using any **React components inside Markdown**:
-
-```jsx
-export const Highlight = ({children, color}) => (
-  <span
-    style={{
-      backgroundColor: color,
-      borderRadius: '20px',
-      color: '#fff',
-      padding: '10px',
-      cursor: 'pointer',
-    }}
-    onClick={() => {
-      alert(`You clicked the color ${color} with label ${children}`)
-    }}>
-    {children}
-  </span>
-);
-
-This is <Highlight color="#25c2a0">Docusaurus green</Highlight> !
-
-This is <Highlight color="#1877F2">Facebook blue</Highlight> !

-# Manage Docs Versions
-
-Docusaurus can manage multiple versions of your docs.
-
-## Create a docs version
-
-Release a version 1.0 of your project:
-
-```bash
-npm run docusaurus docs:version 1.0
-```
-
-The `docs` folder is copied into `versioned_docs/version-1.0` and `versions.json` is created.
-
-Your docs now have 2 versions:
-
-- `1.0` at `http://localhost:3000/docs/` for the version 1.0 docs
-- `current` at `http://localhost:3000/docs/next/` for the **upcoming, unreleased docs**
-
-## Add a Version Dropdown
-
-To navigate seamlessly across versions, add a version dropdown.
-
-Modify the `docusaurus.config.js` file:
-
-```js title="docusaurus.config.js"
-export default {
-  themeConfig: {
-    navbar: {
-      items: [
-        // highlight-start
-        {
-          type: 'docsVersionDropdown',
-        },
-        // highlight-end
-      ],
-    },
-  },
-};
-```
-
-The docs version dropdown appears in your navbar:
-
-![Docs Version Dropdown](./img/docsVersionDropdown.png)
-
-## Update an existing version
-
-It is possible to edit versioned docs in their respective folder:
-
-- `versioned_docs/version-1.0/hello.md` updates `http://localhost:3000/docs/hello`
-- `docs/hello.md` updates `http://localhost:3000/docs/next/hello`

-# Translate your site
-
-Let's translate `docs/intro.md` to French.
-
-## Configure i18n
-
-Modify `docusaurus.config.js` to add support for the `fr` locale:
-
-```js title="docusaurus.config.js"
-export default {
-  i18n: {
-    defaultLocale: 'en',
-    locales: ['en', 'fr'],
-  },
-};
-```
-
-## Translate a doc
-
-Copy the `docs/intro.md` file to the `i18n/fr` folder:
-
-```bash
-mkdir -p i18n/fr/docusaurus-plugin-content-docs/current/
-
-cp docs/intro.md i18n/fr/docusaurus-plugin-content-docs/current/intro.md
-```
-
-Translate `i18n/fr/docusaurus-plugin-content-docs/current/intro.md` in French.
-
-## Start your localized site
-
-Start your site on the French locale:
-
-```bash
-npm run start -- --locale fr
-```
-
-Your localized site is accessible at [http://localhost:3000/fr/](http://localhost:3000/fr/) and the `Getting Started` page is translated.
-
-:::caution
-
-In development, you can only use one locale at a time.
-
-:::
-
-## Add a Locale Dropdown
-
-To navigate seamlessly across languages, add a locale dropdown.
-
-Modify the `docusaurus.config.js` file:
-
-```js title="docusaurus.config.js"
-export default {
-  themeConfig: {
-    navbar: {
-      items: [
-        // highlight-start
-        {
-          type: 'localeDropdown',
-        },
-        // highlight-end
-      ],
-    },
-  },
-};
-```
-
-The locale dropdown now appears in your navbar:
-
-![Locale Dropdown](./img/localeDropdown.png)
-
-## Build your localized site
-
-Build your site for a specific locale:
-
-```bash
-npm run build -- --locale fr
-```
-
-Or build your site to include all the locales at once:
-
-```bash
-npm run build
-```
