+## Quickstart ⚡
+
+Get started with Axolotl in just a few steps! This quickstart guide will walk you through setting up and running a basic fine-tuning task.
+
+**Requirements**: *Nvidia* GPU (Ampere architecture or newer for `bf16` and Flash Attention) or *AMD* GPU, Python >=3.10 and PyTorch >=2.3.1.
+
+```bash
+git clone https://github.com/axolotl-ai-cloud/axolotl
+cd axolotl
+
+pip3 install packaging ninja
+pip3 install -e '.[flash-attn,deepspeed]'
+```
+
+### Usage
+```bash
+# preprocess datasets - optional but recommended
+CUDA_VISIBLE_DEVICES="0" python -m axolotl.cli.preprocess examples/openllama-3b/lora.yml
+
+# finetune lora
+accelerate launch -m axolotl.cli.train examples/openllama-3b/lora.yml
+
+# inference
+accelerate launch -m axolotl.cli.inference examples/openllama-3b/lora.yml \
+    --lora_model_dir="./outputs/lora-out"
+
+# gradio
+accelerate launch -m axolotl.cli.inference examples/openllama-3b/lora.yml \
+    --lora_model_dir="./outputs/lora-out" --gradio
+
+# remote yaml files - the yaml config can be hosted on a public URL
+# Note: the yaml config must directly link to the **raw** yaml
+accelerate launch -m axolotl.cli.train https://raw.githubusercontent.com/axolotl-ai-cloud/axolotl/main/examples/openllama-3b/lora.yml
+```
+
+### Axolotl CLI
+
+If you've installed this package using `pip` from source, we now support a new, more
+streamlined CLI using [click](https://click.palletsprojects.com/en/stable/). Rewriting
+the above commands:
+
+```bash
+# preprocess datasets - optional but recommended
+CUDA_VISIBLE_DEVICES="0" axolotl preprocess examples/openllama-3b/lora.yml
+
+# finetune lora
+axolotl train examples/openllama-3b/lora.yml
+
+# inference
+axolotl inference examples/openllama-3b/lora.yml \
+    --lora-model-dir="./outputs/lora-out"
+
+# gradio
+axolotl inference examples/openllama-3b/lora.yml \
+    --lora-model-dir="./outputs/lora-out" --gradio
+
+# remote yaml files - the yaml config can be hosted on a public URL
+# Note: the yaml config must directly link to the **raw** yaml
+axolotl train https://raw.githubusercontent.com/axolotl-ai-cloud/axolotl/main/examples/openllama-3b/lora.yml
+```
+
+We've also added a new command for fetching `examples` and `deepspeed_configs` to your
+local machine. This will come in handy when installing `axolotl` from PyPI.
+
+```bash
+# Fetch example YAML files (stores in "examples/" folder)
+axolotl fetch examples
+
+# Fetch deepspeed config files (stores in "deepspeed_configs/" folder)
+axolotl fetch deepspeed_configs
+
+# Optionally, specify a destination folder
+axolotl fetch examples --dest path/to/folder
+```

+        "You" (or "Your") shall mean an individual or Legal Entity
+        exercising permissions granted by this License.
+
+        "Source" form shall mean the preferred form for making modifications,
+        including but not limited to software source code, documentation
+        source, and configuration files.
+
+        "Object" form shall mean any form resulting from mechanical
+        transformation or translation of a Source form, including but
+        not limited to compiled object code, generated documentation,
+        and conversions to other media types.
+
+        "Work" shall mean the work of authorship, whether in Source or
+        Object form, made available under the License, as indicated by a
+        copyright notice that is included in or attached to the work
+        (an example is provided in the Appendix below).
+
+        "Derivative Works" shall mean any work, whether in Source or Object
+        form, that is based on (or derived from) the Work and for which the
+        editorial revisions, annotations, elaborations, or other modifications
+        represent, as a whole, an original work of authorship. For the purposes
+        of this License, Derivative Works shall not include works that remain
+        separable from, or merely link (or bind by name) to the interfaces of,
+        the Work and Derivative Works thereof.
+
+        "Contribution" shall mean any work of authorship, including
+        the original version of the Work and any modifications or additions
+        to that Work or Derivative Works thereof, that is intentionally

+        or by an individual or Legal Entity authorized to submit on behalf of
+        the copyright owner. For the purposes of this definition, "submitted"
+        means any form of electronic, verbal, or written communication sent
+        to the Licensor or its representatives, including but not limited to
+        communication on electronic mailing lists, source code control systems,
+        and issue tracking systems that are managed by, or on behalf of, the

+
+        "Contributor" shall mean Licensor and any individual or Legal Entity
+        on behalf of whom a Contribution has been received by Licensor and
+        subsequently incorporated within the Work.
+
+    2. Grant of Copyright License. Subject to the terms and conditions of
+        this License, each Contributor hereby grants to You a perpetual,
+        worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+        copyright license to reproduce, prepare Derivative Works of,
+        publicly display, publicly perform, sublicense, and distribute the
+        Work and such Derivative Works in Source or Object form.
+
+    3. Grant of Patent License. Subject to the terms and conditions of
+        this License, each Contributor hereby grants to You a perpetual,
+        worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+        (except as stated in this section) patent license to make, have made,
+        use, offer to sell, sell, import, and otherwise transfer the Work,
+        where such license applies only to those patent claims licensable
+        by such Contributor that are necessarily infringed by their
+        Contribution(s) alone or by combination of their Contribution(s)
+        with the Work to which such Contribution(s) was submitted. If You
+        institute patent litigation against any entity (including a
+        cross-claim or counterclaim in a lawsuit) alleging that the Work
+        or a Contribution incorporated within the Work constitutes direct
+        or contributory patent infringement, then any patent licenses
+        granted to You under this License for that Work shall terminate
+        as of the date such litigation is filed.
+
+    4. Redistribution. You may reproduce and distribute copies of the
+        Work or Derivative Works thereof in any medium, with or without
+        modifications, and in Source or Object form, provided that You
+        meet the following conditions:
+
+        (a) You must give any other recipients of the Work or
+            Derivative Works a copy of this License; and
+
+        (b) You must cause any modified files to carry prominent notices
+            stating that You changed the files; and
+
+        (c) You must retain, in the Source form of any Derivative Works
+            that You distribute, all copyright, patent, trademark, and
+            attribution notices from the Source form of the Work,
+            excluding those notices that do not pertain to any part of
+            the Derivative Works; and
+
+        (d) If the Work includes a "NOTICE" text file as part of its
+            distribution, then any Derivative Works that You distribute must
+            include a readable copy of the attribution notices contained
+            within such NOTICE file, excluding those notices that do not
+            pertain to any part of the Derivative Works, in at least one
+            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
+            of the NOTICE file are for informational purposes only and
+            do not modify the License. You may add Your own attribution
+            notices within Derivative Works that You distribute, alongside
+            or as an addendum to the NOTICE text from the Work, provided
+            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
+        of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+        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.

 Once upon a time, there was a little car named Beep. Beep loved to go fast and play in the sun. Beep was a healthy car because he always had good fuel. Good fuel made Beep happy and strong. One day, Beep was driving in the park when he saw a big tree. The tree had many leaves that were falling. Beep liked how the leaves fall and wanted to play with them. Beep drove under the tree and watched the leaves fall on him. He laughed and beeped his horn. Beep played with the falling leaves all day. When it was time to go home, Beep knew he needed more fuel. He went to the fuel place and got more healthy fuel. Now, Beep was ready to go fast and play again the next day. And Beep lived happily ever after.
 One day, a little fish named Fin was swimming near the shore. He saw a big crab and wanted to be friends. "Hi, I am Fin. Do you want to play?" asked the little fish. The crab looked at Fin and said, "No, I don't want to play. I am cold and I don't feel fine." Fin felt sad but wanted to help the crab feel better. He swam away and thought of a plan. He remembered that the sun could make things warm. So, Fin swam to the top of the water and called to the sun, "Please, sun, help my new friend feel fine and not freeze!" The sun heard Fin's call and shone its warm light on the shore. The crab started to feel better and not so cold. He saw Fin and said, "Thank you, little fish, for making me feel fine. I don't feel like I will freeze now. Let's play together!" And so, Fin and the crab played and became good friends.
