+### Prompt Strategies
+
+Fabric also implements prompt strategies like "Chain of Thought" or "Chain of Draft" which can
+be used in addition to the basic patterns.
+
+See the [Thinking Faster by Writing Less](https://arxiv.org/pdf/2502.18600) paper and
+the [Thought Generation section of Learn Prompting](https://learnprompting.org/docs/advanced/thought_generation/introduction) for examples of prompt strategies.
+
+Each strategy is available as a small `json` file in the [`/strategies`](https://github.com/danielmiessler/fabric/tree/main/strategies) directory.
+
+The prompt modification of the strategy is applied to the system prompt and passed on to the
+LLM in the chat session.
+
+Use `fabric -S` and select the option to install the strategies in your `~/.config/fabric` directory.
