 ## Development
+### Setup
+Before developing, you have to set up environment. Misskey requires Redis, PostgreSQL, and FFmpeg.
+
+You would want to install Meilisearch to experiment related features. Technically, meilisearch is not strict requirement, but some features and tests require it.
+
+There are a few ways to proceed.
+
+#### Use system-wide software
+You could install them in system-wide (such as from package manager).
+
+#### Use `docker compose`
+You could obtain middleware container by typing `docker compose -f $PROJECT_ROOT/compose.local-db.yml up -d`.
+
+#### Use Devcontainer
+Devcontainer also has necessary setting. This method can be done by connecting from VSCode.
+
+Instead of running `pnpm` locally, you can use Dev Container to set up your development environment.
+To use Dev Container, open the project directory on VSCode with Dev Containers installed.  
+**Note:** If you are using Windows, please clone the repository with WSL. Using Git for Windows will result in broken files due to the difference in how newlines are handled.
+
+It will run the following command automatically inside the container.
+``` bash
+git submodule update --init
+pnpm install --frozen-lockfile
+cp .devcontainer/devcontainer.yml .config/default.yml
+pnpm build
+pnpm migrate
+```
+
+After finishing the migration, you can proceed.
