+# Megatron installation script for mdx/LLM-jp v3 models
+
+LLM-jp v3モデルを作成するためのMegatron環境をllm-jpクラスタにインストールするためのスクリプトです。
+System Pythonやpyenvに依存しない閉じた環境を指定したディレクトリ上に構築します。
+
+## Usage
+
+### Build
+
+インストール処理のためにCPUリソースを使用します。
+時間がかかるので気長に待って下さい。
+
+```shell
+git clone https://github.com/llm-jp/scripts
+cd scripts/pretrain/installers/v3-megatron-mdx
+
+# ~/myspace に環境をインストールします。
+bash install.sh ~/myspace
+```
+
+### Check
+
+インストール終了後、下記のようなディレクトリ構造が構築されています。
+
+```
+~/myspace/
+    example/              サンプルスクリプト
+    installer_envvar.log  インストール開始後に記録した環境変数の一覧
+    install.sh            使用したインストールスクリプト
+    python/               Python実行環境
+    requirements.txt      venvに事前インストールされたライブラリ一覧
+    scripts/              各種の環境設定用スクリプト
+    src/                  個別ダウンロードされたライブラリ
+    venv/                 Python仮想環境
+```
+
+インストールした環境で正常に事前学習ジョブを起動できるかどうかを確認します。
+
+```shell
+cd ~/myspace
+bash example/mpi_wrapper.sh
+```
+W&Bにtrain lossが記録されるのを確認したらジョブを止めてください。
