+FAFO Technology Tree
+====================
+This repository tracks our "technology tree" — the steps towards our
+overarching goals.
+
+A description of how this tech tree works can be found below. See
+[Working with the Tech Tree](#working-with-the-tech-tree).
+
+## Full Technology Tree
+Below, you can see the full technology tree. The issues in this repository
+track the tree's elements. For a better overview, check each issue for a
+filtered subtree that contains just the elements related to it.
+
+
+
+## Working with the Tech Tree
+Fundamentally, the tech tree is built from the issues in this repository and
+their interdependencies. For elements to be reached, create new issues and
+select one of the `Type/###` labels to declare what kind it is:
+
+- Type/**Equipment** 🔬 — A piece of machinery that we need to acquire or get
+ running. Mainly things that can be bought instead of built.
+
+- Type/**Process** ⚗️ — A process we need to achieve. This means we need to
+ become able to perform this process reliably.
+
+- Type/**Development** 🔩 — A device, software, or other thing we need to develop.
+ This is _engineering_ work; making use of existing knowledge to build
+ something useful.
+
+- Type/**Research** 🧪 — A topic that we can or must research to unlock future
+ capabilities. In contrast to _Development_ elements, we cannot make use of
+ prior art here. So less engineering and more _science_.
+
+#### Dependencies
+Once created, add dependencies between issues to model their relationships.
+The CI of this repository will automatically update the tech tree accordingly.
+In addition, each issue gets a partial representation of the subtree of
+elements directly related to it. You can quickly see what is still missing to
+achieve a particular element. And also what next steps will be unlocked once
+an element has been achieved.
+
+There are no distinct types of dependencies. This was a choice in the name of
+keeping the model simple. All dependencies are hard requirements. But also
+check the next section on more thoughts about this...
+
+#### Modelling Approach
+Finding the right balance between model complexity and expressiveness is
+tricky. Following are some guidelines for adding elements to this tech tree.
+
+All elements should have a few fundamental properties, to keep the model consistent:
+
+- Elements shall have a **clear and unambiguous acceptance criterion**. If
+ necessary, this can be elaborated on in the issue body. "SEM Imaging" leaves
+ open what scale we can image reliably. It may be sensible to add multiple
+ elements to model progress in such a domain.
+
+- Elements shall be **actionable**, in the sense that someone can put in effort to
+ achieve them. Having a good acceptance criterion does most of the heavy
+ lifting here.
+
+- Elements shall be **necessary** for our bigger visions. Ultimate elements
+ (elements that nothing depends on) should get special consideration in this
+ regard. If you have visions of your own, it is of course fine to make an
+ ultimate element for them.
+
+- Elements shall have a scope/granularity size that is appropriate for tracking
+ progress. We will need to figure this out as we go.
+
+Generally, our tech tree is a living object. It should be updated as we figure
+out more elements to be tracked and their dependencies.
+
+One topic of particular interest are "path choices". We can either use
+technology A or technology B to achieve element C:
+
+```mermaid
+flowchart BT
+ classDef eoi fill:#fff, stroke:#000, color:#000;
+ classDef dependant fill:#fff, stroke:#888, color:#888;
+ classDef dep_missing fill:#fcc, stroke:#800, color:#000;
+ classDef dep_assigned fill:#ffa, stroke:#a50, color:#000;
+ classDef dep_completed fill:#afa, stroke:#080, color:#000;
+ 0:::dep_missing
+ 0["#1 | MISSING
Process
Technology A"]
+ 1:::dep_completed
+ 1["#2 | COMPLETED
Process
Technology B"]
+ 2:::eoi
+ 2["#3 | MISSING
Process
Element C"]
+ 2 --> 0
+ 2 --> 1
+```
+
+Dependencies cannot express such choices. Instead, please follow this approach:
+
+- Initially, all potential path choice dependencies are added. The issue body
+ shall document the choice options and implications.
+
+- When we get closer to the element of interest, we make the choice of what
+ path to pursue. At this time, the other dependencies are dropped. The
+ tech-tree now only documents the path choice we have made.
+
+Another situation we will encounter is the need to use generic equipment for
+specific purposes. If the specific purpose is non-trivial, it shall be
+modelled as an intermediate _Process_ element in-between:
+
+```mermaid
+flowchart BT
+ classDef eoi fill:#fff, stroke:#000, color:#000;
+ classDef dependant fill:#fff, stroke:#888, color:#888;
+ classDef dep_missing fill:#fcc, stroke:#800, color:#000;
+ classDef dep_assigned fill:#ffa, stroke:#a50, color:#000;
+ classDef dep_completed fill:#afa, stroke:#080, color:#000;
+ 0:::dep_missing
+ 0["#2 | MISSING
Process
Processing X using machine A"]
+ 1:::dep_completed
+ 1["#1 | COMPLETED
Equipment
Generic Machine A"]
+ 2:::eoi
+ 2["#3 | MISSING
Process
Element C"]
+ 2 --> 0
+ 0 --> 1
+```
+
+
+
+#### Element Status
+The status of each element is determined as follows:
+
+- **MISSING** when the element has not yet been achieved.
+- **ASSIGNED** when the issue has been assigned to someone. This means we are making progress!
+- **COMPLETED** when the issue is labelled `Completed`. Achievement unlocked!
+
+#### Important notes
+There are a few gotchas that you should be aware of:
+
+- The CI will not automatically update when changing dependencies,
+ unfortunately. You can force a trigger by editing the issue body or quickly
+ adding and then removing the `Stale` label.
+
+- Issues that should no longer be a part of the techtree should either be
+ deleted (looses all tracking) or they can be made inert by closing them.
