+# Beskrivelse
+
+## Hvad programmet gør
+
+Programmet følger lektionens trin:
+
+1. `read_csv` læser optællingsfilen.
+2. `count_by_fur_color` tæller observationerne af Gray, Cinnamon og Black.
+3. `build_summary` gør tallene til rækkerne i en opsummering.
+4. `write_csv` skriver opsummeringen til `squirrel_count.csv`.
+
+På optællingsfilen fra 2018 er resultatet Gray 2473, Cinnamon 392 og Black 103. Observationer uden pelsfarve tælles ikke med i nogen af dem.
+
+## Hvorfor ikke Pandas
+
+Lektionen bruger Pandas. Dette projekt bruger kun Pythons standardbibliotek (`csv` og `collections.Counter`), så der ikke er noget at installere for at køre det. Beslutningen er beskrevet som ADR-0001 i repositoryet.
+
+## Opbygning
+
+| Sti | Indhold |
+| --- | --- |
+| `src/squirrel/census.py` | De fire trin ovenfor |
+| `src/squirrel/cli.py` | Kommandolinjen, `python -m squirrel` |
+| `src/squirrel/constants.py` | Alle konstanter, defineret ét sted |
+| `tests/` | pytest-testene |
+| `docs/` | Business case, plan, modeller, reviewposter |
+
+## Kvalitet
+
+Alle dokumenter og al kode er gennemgået mod tjeklisterne i SQA- og QC-frameworket i autonom tilstand: reviewer er en AI-stedfortræder, så reviewene er ikke uafhængige.

+# Description
+
+## What it does
+
+The program follows the steps of the lecture:
+
+1. `read_csv` reads the census file.
+2. `count_by_fur_color` counts the sightings of Gray, Cinnamon and Black.
+3. `build_summary` turns the counts into the rows of a summary.
+4. `write_csv` writes the summary to `squirrel_count.csv`.
+
+On the 2018 census file the result is Gray 2473, Cinnamon 392 and Black 103. Sightings without a fur colour are counted in none of them.
+
+## Why no Pandas
+
+The lecture uses Pandas. This project uses only the Python standard library (`csv` and `collections.Counter`) so that there is nothing to install to run it. The decision is recorded as ADR-0001 in the repository.
+
+## Layout
+
+| Path | Content |
+| --- | --- |
+| `src/squirrel/census.py` | The four steps above |
+| `src/squirrel/cli.py` | The command line, `python -m squirrel` |
+| `src/squirrel/constants.py` | Every literal, defined once |
+| `tests/` | The pytest tests |
+| `docs/` | Business case, plan, models, review records |
+
+## Quality
+
+Every document and every piece of code was reviewed against the checklists of the SQA and QC framework, in autonomous mode: the reviewer is an AI stand-in, so the reviews are not independent.

+# Penerangan
+
+## Apa yang dilakukan program
+
+Program mengikut langkah dalam pelajaran:
+
+1. `read_csv` membaca fail banci.
+2. `count_by_fur_color` mengira pemerhatian Gray, Cinnamon dan Black.
+3. `build_summary` menukar kiraan kepada baris ringkasan.
+4. `write_csv` menulis ringkasan ke `squirrel_count.csv`.
+
+Pada fail banci 2018 hasilnya ialah Gray 2473, Cinnamon 392 dan Black 103. Pemerhatian tanpa warna bulu tidak dikira dalam mana-mana satu.
+
+## Mengapa tidak menggunakan Pandas
+
+Pelajaran menggunakan Pandas. Projek ini hanya menggunakan pustaka standard Python (`csv` dan `collections.Counter`) supaya tiada apa-apa untuk dipasang bagi menjalankannya. Keputusan itu direkodkan sebagai ADR-0001 dalam repositori.
+
+## Susun atur
+
+| Laluan | Kandungan |
+| --- | --- |
+| `src/squirrel/census.py` | Empat langkah di atas |
+| `src/squirrel/cli.py` | Baris perintah, `python -m squirrel` |
+| `src/squirrel/constants.py` | Semua pemalar, ditakrif sekali |
+| `tests/` | Ujian pytest |
+| `docs/` | Kes perniagaan, pelan, model, rekod semakan |
+
+## Kualiti
+
+Setiap dokumen dan kod disemak berdasarkan senarai semak rangka kerja SQA dan QC dalam mod autonomi: penyemak ialah pengganti AI, jadi semakan itu tidak bebas.
