+
+## Scope of contributions
+
+This repository accepts two main types of contributions:
+
+- **Meetup-related content**: topics, links, summaries, and corrections for specific Socratic seminars.
+- **General repository maintenance**: documentation, layouts, scripts, CI configuration, and other housekeeping.
+
+This guide focuses on defining what is in scope and how contributions should be made.
+Workflow and naming rules apply to all contribution types.
+
+
+### Accepted contributions
+
+#### General repository maintenance
+- Documentation improvements
+- Layout and styling changes
+- Scripts, tooling, and CI configuration
+- Refactors that improve consistency or maintainability
+
+#### Meetup-related contributions
+- Topic summaries and background material
+- Curated resource lists (papers, PRs, BIPs, mailing-list threads)
+- Corrections and structural improvements
+- New templates that improve the contributor experience
+
+
+### Out of scope
+
+- Opinionated or editorial content unless explicitly approved
+- Content unrelated to Bitcoin or Socratic Seminar discussions
+- Promotional or low-signal material
+
+---
+
+If you only want to **propose topics** (without editing files yourself), you can open an Issue like:
+
+> `Topics for Socratic #NNN`
+
+and list the suggested links. In that case, the sections **Citation & link policy**, and **Style guide (Markdown)** are the most relevant.
+
+---
+
+## Citation & link policy
+
+This archive is meant to point to **public resources** and capture **what was discussed**, not who said what in the room.
+
+When adding topics:
+
+- Prefer **canonical, stable URLs**:
+  - Bitcoin Core / other repos on GitHub
+  - BIPs from the official BIPs repository
+  - bitcoin-dev / delvingbitcoin threads
+  - arXiv papers, project documentation, blog posts
+- Avoid:
+  - URL shorteners whenever possible
+  - Tracking parameters (`utm_*`, etc.) when it doesn't break the link
+- X/Twitter links are acceptable if they are the main source
+- Respect privacy:
+  - Don't link to **private chat logs**, closed groups, or personal DMs
+  - Don't include personal data about attendees (emails, phone numbers, doxxing, etc.)
+  - When summarizing ideas from participants, it's fine to keep it anonymous unless they already publish under that identity
+
+---
+
+## Style guide (Markdown)
+
+To keep the archive consistent and easy to read:
+
+- **Headings**
+  - Start sections at `##` and use `###` for subsections.
+  - Use a small, predictable set of sections, for example:
+    - `## Avisos` / `## Announcements`
+    - `### Bitcoin`, `### Lightning`, `### Mining`, `### Maneiro` / `### Misc`.
+
+- **Lists**
+  - Use bullet lists for topics, with descriptive link text:
+
+        * [BIP-444: Reduced Data Temporary Softfork](https://github.com/bitcoin/bips/pull/2017) - softfork proposal to reduce block data.
+        * [LND 0.20.0-rc2](https://github.com/lightningnetwork/lnd/releases/tag/v0.20.0-beta.rc2)
+
+  - Prefer **descriptive link text** instead of bare URLs.
+
+- **Language**
+  - File content can follow the meetup's usual language (e.g. Portuguese or English).
+  - **Commit messages and PR descriptions should always be in English.**
+
+- **Formatting details**
+  - Try to wrap lines around ~100 characters to keep diffs readable.
+  - Avoid trailing whitespace and unnecessary blank lines.
+  - Keep YAML front-matter and indentation consistent with existing files.
+  - When adding new files, copy from a recent existing post/template to match structure.
+
+- **Code & configuration**
+  - If you touch any scripts or configuration files:
+    - Follow the existing style in that language (indentation, quoting, etc.).
+    - Prefer small, focused changes that are easy to review.
+
+---
+
+## Contribution workflow
+
+1. **Open an Issue** (optional but recommended for bigger changes) and describe what you'll add or fix.
+2. **Fork** the repo and create a feature branch:
+
+       git checkout -b docs/2025-10-seminar-notes
+
+3. **Make your changes** and commit them with a meaningful message.
+4. **Push your changes** to your forked repository:
+
+       git push origin docs/2025-10-seminar-notes
+
+5. **Open a Pull Request (PR)** to the main repository and link it to the Issue (if applicable).
+
+Try to keep each PR focused on **one meetup** or **one logical change** (e.g. "fix broken links in September 2025 post").
+
+---
+
+## Branch naming conventions
+
+Use short, lowercase names with words separated by hyphens and, when useful, a simple prefix.
+
+Recommended patterns:
+
+- `feat/...` - new content or features
+- `fix/...` - bug fixes or corrections
+- `docs/...` - documentation-only changes (README, CONTRIBUTING, templates)
+- `chore/...` - maintenance, refactors, or build-related changes
+
+Examples:
+
+- `feat/2025-11-socratic-040`
+- `docs/add-contributing-guide`
+- `fix/typo-2025-09-topics`
+- `chore/reorder-readme`
+
+If you create the branch from the GitHub UI, try to avoid generic names like `patch-1` and prefer something descriptive.
+
+---
+
+## Commit message conventions
+
+We follow a style based on [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/), for example:
+
+- `feat: nov meetup`
+- `feat(header): add X (@curitibabitdevs) link to navigation`
+- `feat(_posts): arkade announcement`
+- `fix(_posts): update meetup links`
+- `fix: remove duplicated topics`
+- `2025-09 (#68)`
+
+General rules:
+
+- Write commit messages in **English**.
+- Start with a **type**, optional **scope**, then a **short description**:
+
+      <type>(optional-scope): short description
+
+- Keep the subject line concise (ideally ≤ 50 characters).
+- Use the body (optional) to explain **why** you're changing something, not just **what** changed.
+
+Common types:
+
+- `feat` - new posts, new sections, or new functionality
+- `fix` - corrections that change what readers/users see (broken links, wrong dates, incorrect metadata, typos that change meaning)
+- `docs` - README, CONTRIBUTING, or other documentation-only updates
+- `chore` - repository maintenance (moving/renaming files, updating CI or dependencies, non-user-visible cleanups)
+- `refactor` - improving structure of build/automation scripts without changing their output
+- `style` - purely stylistic changes (whitespace, line wrapping, indentation) with no change in meaning
+- `test` - adding or adjusting tests (if the repo grows tests later)
+
+In practice:
+
+- Use `fix` when something is "wrong" from the reader's point of view (404 links, incorrect info, broken formatting in the rendered page).
+- Use `style` when you're only changing formatting/whitespace for readability.
+- Use `refactor` when you're improving the structure of helper scripts or config without changing behavior.
+- Use `chore` for general housekeeping that doesn't fit the above (moving posts, updating CI configs, bumping dependencies).
+
+Examples for this repository:
+
+- `feat(topics): add socratic seminar 040`
+- `feat(posts): add nov 2025 meetup`
+- `fix(links): update delvingbitcoin URLs for september`
+- `docs: add contribution guidelines`
+- `chore(posts): reorder sections by topic`
+
+If you are working on a seminar topic file and that's the only change in the PR, a short and focused subject like below is fine:
+
+- `2025-09: add socratic seminar topics`
+
+---
+
+## Pull Request (PR) process
+
+When opening a PR, please:
+
+1. **Keep it focused.**  
+   Ideally, one PR = one meetup post or one small set of related fixes.
+
+2. **Sync with `main`** before opening:
+
+       git fetch upstream
+       git checkout main
+       git pull upstream main
+       git checkout your-branch
+       git rebase main
+
+3. **Run checks locally** if the repository provides them (e.g. linters, test scripts, or static site build).  
+   Example: `make` / `make test` / `jekyll serve`, as documented in the README.
+
+4. **Write a clear PR description.**  
+   A simple template you can follow:
+
+       Summary
+       -------
+       - Add topics for the November 2025 Socratic seminar.
+       - Include links to BIPs, PRs, and Delving Bitcoin threads.
+
+       Details
+       -------
+       - Meetup date: 2025-11-05
+       - Sections: Announcements, Bitcoin, Lightning, Misc
+
+       Checklist
+       ---------
+       - [ ] Links render correctly in Markdown preview
+       - [ ] No private or non-public resources referenced
+
+5. **Address review comments.**
+   - Push follow-up commits to the same branch.
+   - **Clean history approach**: Feel free to amend commits and force-push with `--force-with-lease` to keep history clean—just leave a comment in the PR describing your changes.
+   - Alternatively, you can add new commits for each review round; maintainers will squash at merge time if needed.
+
+---
+## Squashing & merge strategy
+
+To keep the history readable, we generally:
+
+- Use **"Squash and merge"** for most PRs so that each PR becomes a **single logical commit** on `main` (often one commit per meetup or per change-set).
+- Occasionally keep multiple commits (regular merge) when the history inside the PR is meaningful on its own.
+
+Force-pushing (`git push --force-with-lease`) to your **own feature branches** is a common practice to keep the commit history clean, especially **before** a PR is opened or when you're squashing WIP commits.
+
+Once a PR already has review comments, prefer adding new commits instead of rewriting history, unless a maintainer explicitly asks you to rebase or clean up the branch.
+
+What this means for contributors:
+
+- You **don't need** perfectly clean commits while you are iterating on your branch.
+- It's nice (but not mandatory) to clean up obvious "WIP" commits before asking for review.
+- Maintainers will pick an appropriate merge strategy. If we squash, we'll make sure the final commit message follows the conventions above.
+
+Please:
+
+- Never push directly to `main`.
+- Avoid force-pushing to branches that already have review comments unless you're explicitly asked to rebase/cleanup.
