Learn Any New Framework in 48 Hours: Ritsu's Docs-to-Code Workflow for Engineers

Your team just voted to migrate the service to a new framework. The announcement ended with "you have two days to ramp up." You open the official docs. There are 47 pages. The homepage has a quickstart that's either too shallow (hello world, doesn't reflect anything real) or too deep (full production config on page one). You start reading. Forty minutes later you're skimming, you've lost the plot, and you're about to open Reddit.

This is tutorial hell and it's an extremely common failure mode for experienced engineers. You know how to code. You don't know how to efficiently acquire a new mental model of a framework.

The core problem: framework docs are organised for reference, not for learning. They assume you'll eventually read everything. You won't, and you shouldn't. What you need is a learning path that takes you from zero to shipping production-quality code in this framework, as fast as possible, through strategically-chosen real tasks.

That's what this workflow builds. Works for anything: tRPC, Zustand, SolidJS, Rust Axum, Go Fiber, SwiftUI, Flutter, Kubernetes, Terraform, etc. It's a general protocol — the framework is the variable.

Prerequisites

• A free Ritsu account (Plus tier worth it if you're loading large docs).
• The framework's official documentation. Either the URL of the docs site or the PDF if they publish one. Skip unofficial tutorials initially — they're how you end up with out-of-date idioms baked into your mental model.
• A real project idea in the new framework. "Rebuild our auth service in tRPC" or "Port the search page to Zustand." Not "build a todo app." Real projects force real decisions; toy examples teach you nothing.
• 48 hours of serious engagement (this doesn't work in 30-minute bursts between other work).

What you'll build

By end of Day 2 you'll have:

1. A structured mental model of the framework: the core abstractions, the mental model it's imposing, where it sits in the stack.
2. An idiomatic Hello World — not the docs' toy example but a small piece of your real project, implemented idiomatically.
3. A feature shipped in the new framework. Not merged to main (yet), but running end-to-end on a branch.

The last one is the real test. If you haven't shipped something tiny-but-real by hour 48, you haven't learned the framework — you've read about it.

Steps

1. Hour 0-1: Load the docs and get the shape

Create a new Ritsu session. Name it "[Framework] — [Your project]". Upload the docs site as a URL source (Ritsu will crawl it) OR the docs PDF if available. If the framework has a tutorial section, upload that too.

Before you read anything, type:

/explain — what is this framework, what problem does it solve, and what's the mental model the user needs to adopt?

This is the most important question you'll ask. Every framework imposes a mental model — a set of abstractions and constraints that are the framework's actual value proposition. React imposes components-as-functions + unidirectional data flow. Kubernetes imposes declarative desired-state. Rust imposes ownership. Your goal isn't to memorise the API; it's to adopt the mental model.

Ritsu distills this in two paragraphs. Read them. Let them land. Everything from here on is applied mental model.

2. Hour 1-4: Get the concept scaffold

Now you want the skeleton of the framework — not all of it, the load-bearing core. Type:

/start — what are the 5-7 core concepts I need to master first? Rank them in the order I should learn them.

Ritsu ranks core concepts by dependency (you need X before Y) and frequency (how often you'll encounter them). A typical ranking for, say, tRPC v11 might be: [Router → Procedure → Input/Output types → Context → Middleware → Error handling → Client usage]. For Kubernetes it's [Pod → Service → Deployment → ConfigMap → Namespace → Ingress → RBAC].

For each concept, in order:

/eli5 [concept]
/why does [concept] exist in this framework? What does it replace from other frameworks?
/code — minimal working example of [concept]

The /code output is yours to study. Read it. Then — and this is the critical step — type it out yourself in your editor. Not copy-paste. Type it. Muscle memory for a framework is built through fingers, not eyes. This is the difference between engineers who claim to know a framework and engineers who actually do.

Ask clarifying questions: "why pass X as a prop here instead of using context?" or "what happens if I omit this field?" Ritsu answers with framework-specific reasoning, which is exactly what you need.

3. Hour 4-12: Build the idiomatic hello world

Pick a small real problem from your actual project. Not the whole project. A single endpoint, a single component, a single resource. "User profile fetch endpoint" or "search input component." Something with clear inputs and outputs that takes 2-3 hours to build.

Type:

/explain how this specific thing [describe briefly] is built idiomatically in [framework]. Show me the structure before the code.

Ritsu gives you a structural plan: which files to create, what goes in each, how they connect. Build it. Ask questions as you go:

/why is this in [file A] and not [file B]?
/what's the convention for naming [X] in this framework?

When you hit a wall (and you will), paste the error:

[paste error]. What's going on and how do I fix it?

Ritsu maps the error to the underlying framework concept. Often the error is "you're thinking in [old framework's] model but this framework does X differently" — at which point you get a free mental-model correction that'll save you hours of future pain.

When the feature works, you're a quarter of the way there. Don't celebrate too hard — a lot of engineers stop here and claim they know the framework. They don't. They know a toy. Continue.

4. Hour 12-24: Drill the idioms

Now you move from "I can make it work" to "I can make it work well." This is the part where most self-taught framework learners plateau for months. The workflow accelerates it.

For the code you wrote in step 3, type:

/review my code. Is it idiomatic for this framework? What would a senior engineer do differently?

Ritsu critiques your code with framework-specific conventions: "You're using a useEffect here where most React developers use useMemo for derived state." Or: "This tRPC procedure would typically be a mutation, not a query, because it writes." Or: "This Kubernetes YAML is declarative but you're imperatively patching — use a kustomization instead."

These are the dozens of micro-decisions that separate idiomatic code from "works but feels off." Adopt each correction. Re-type the improved version. Log why each change matters — you're building a mental checklist you'll use on every future project.

Then drill harder:

/quiz — 10 questions on [framework]'s idioms, edge cases, and gotchas.

Take the quiz. Treat wrong answers as gaps to patch, not tests to fail. Re-run the quiz after patching. By the time you consistently score 90%+, you have the idioms internalised.

5. Hour 24-48: Ship real code

This is the final test. Pick a real task from your project backlog — something a teammate would also consider substantial. Implement it end-to-end in the new framework. No shortcuts, no "I'll refactor later" hacks.

Along the way, use Ritsu as a senior engineer sitting next to you:

/review this PR before I push it
/what tests should I write for this?
/what are the edge cases I'm probably missing?

When you open the PR on Day 3 morning, you'll have (a) shipped a real feature, (b) internalised the framework's mental model, (c) learned the idioms well enough that code review comments on your PR will be about design choices, not framework basics.

You're ramped.

Troubleshooting

"The docs are huge — 500+ pages — and I don't know which parts matter." Upload all of them. Ritsu handles large docs natively and will prioritise the load-bearing concepts in step 2. Don't try to pre-curate.

"The framework is new and has breaking changes in every minor version." Paste the current version number at the start of the session: I'm using [framework] v3.2.1. Ritsu scopes its answers to that version's API. This avoids the "chatbot gives me an answer that's 2 years out of date" problem that burns so many engineers.

"Every example I get from Ritsu assumes TypeScript / Python / Go and I'm using [other language]." Specify upfront: I'm working in Rust. Show examples in idiomatic Rust with proper error handling, not JS-style exceptions. Ritsu adapts throughout the session.

"I've reached step 3 but I don't have time to build a real feature in the next 24 hours." Run step 3 anyway, with a scaled-down real feature. If you can't spare 6 hours, you haven't budgeted enough time for this framework migration and you should push back on the deadline. Attempting to learn a framework without building something real in it is measurable resume fraud; you won't actually know it.

"My code review in step 4 had ten suggestions. I don't have time to address all of them." Address the top 3 the model flags as "significantly more idiomatic." Defer the rest to a follow-up refactor. You're trying to move up the skill curve, not shoot for perfection on day one.

Try it yourself

You have a framework to learn. You have 48 hours. The worst possible use of those hours is reading the docs linearly and hoping comprehension emerges. The best possible use is the workflow above.

Drop the docs URL below and tell Ritsu what you're building. In five minutes you'll have a learning plan that gets you shipping by Wednesday.

The best engineers aren't the ones who memorise frameworks. They're the ones who can acquire a new framework's mental model in a weekend and start producing real work. That's a skill. This workflow is how you practice it.
