+# General
+
+Respect others.
+
+Do not say mean things or show contempt, even if there is a difference in skill.
+
+Do not be aggressive in disagreements.
+
+Do not deny any identity of the other person.
+
+Do not post anything that is severely offensive to others.
+
+Do not spam, fish or troll.
+
+If you see someone who you think is violating this Code of Conduct, please contact the [administrator](moderation.erglang@gmail.com) immediately. We will take appropriate action.
+
+## Development
+
+Requests are always welcome, but please keep in mind that they will not always be accepted. Many issues have trade-offs.
+
+Don't intercept issues that others have been assigned (Check assignees on GitHub). If it is considered too difficult for one person to handle it, we will call for more support.
+
+Before proposing a new feature, consider whether that feature could be easily solved by combining existing features.
+
+Please write code in a style that is standardized by the Erg team and languages.

+
+他者を尊重しましょう。
+
+スキルに差があっても、意地悪なことを言ったり侮蔑したりしてはいけません。
+
+意見の相違があっても、攻撃的になってはいけません。
+
+他者のいかなるアイデンティティも否定してはいけません。
+

+
+## 開発・実装に関して
+
+リクエストは常に受け付けますが、常に採用されるとは限らないと心に留めておいてください。多くの問題には、トレードオフが存在します。
+
+他者がアサインされたイシューを横取りするのはやめましょう(GitHubでassigneesを確認してください)。一人では手に余ると判断された場合は、さらに応援を募ります。
+
+機能の提案をする前に、その機能が既存の機能を組み合わせて容易に解決できないか考えてください。
+
+Ergチームや言語で標準とされるスタイルのコードを書いてください。
