+# Workshop
+
+> [!important] 0. Read first
+> - **Notes are the main clues** to know how to behave in the space. Reading all signs is the first and most important action when you enter.
+> - There is a **manager** for the workshop — their name will be written on the **main board**.
+
+## Stigmergy — The Principle of Self-Organization
+
+Stigmergy is the mode of organization used by ants, termites, and Wikipedia. It works through traces left in the environment that guide the next person's action.
+
+### Stigmergic rules
+
+1. **Observe** the clues (based on the signs, or what you know already)
+2. **Take the action** you feel like doing
+3. **Leave clues** to be read by the next person
+
+---
+
+## 1. Clean
+
+- The workshop is a **clean space**. Wherever you see dirt, clean it up.
+- At the **end of a working day**, take 15 minutes to tidy up.
+- In the morning, the workshop should always be clean for whoever enters next.
+
+### Where to find cleaning supplies
+
+> [!info] 🪧 Sign — Bottom left
+> **Cleaning materials**
+> - Brooms
+> - Metal brush
+> - Cobweb duster (spiderweb stick)
+> - Small brush and shovel
+
+> [!info] 🪧 Sign — Bottom right
+> **Bins**
+> - Plastic
+> - Paper
+> - Metal — to recycle / re-use / upcycle
+> - Metal scrap
+> - Sawdust
+> - Woodchips
+> - Wood scraps (large wheeled bin)
+
+> [!note] Each bin has a label showing what to do when it is full — read it.
+
+---
+
+## 2. Organize
+
+- The workshop aims for **crystal-clear organization**.
+- Organization is an **iterative process** toward perfection. If you have an improvement to propose, **make it noticeable** — ideally on the workshop space at [forum.ariege.io](https://forum.ariege.io).
+- **Mark and write signs on shelves** to show where items belong.
+
+---
+
+## 3. Improve
+
+- Make this a **beautiful and enjoyable** working environment.
+- If something is missing, add it to the **wishlist on the blackboard** in the workshop.
+- Propose or join current building projects.
+- Repair / upcycle / craft / enjoy.
+
+---
+
+## Tools' Rules
+
+- A **colored-tape system** marks personal tools and collective tools. **Collective tools are marked with white tape.**
+- If you want to use a **personal tool, ask the owner first.** The current color code is shown on the labels (see the sign in the workshop).
+- If you want to use **electric collective tools for the first time, ask the manager first** — even if you already know how to use them.
+- **Act with better care than if the tools were your own.**
+- If a **machine or tool breaks**, take it out of circulation and tell the manager (and the tool's owner, if it's a personal tool). Don't keep using it or pass it on to be used.
+
+### Safety & first aid
+
+> [!warning] Injury or accident
+> - **First aid kit** is in the workshop (look for the arrow). A QR code on the kit links to emergency contacts.
+> - A **second first aid kit** is in the chateau, to the right.
+> - For serious injuries, see [[../emergency/medical|Medical Emergency]].

+
+## Wishlist
+
+The wishlist lives on the **blackboard in the workshop** — add items there as you notice them. We keep it out of the docs because it changes constantly; the board is the source of truth.
