| Library | Download | What’s inside |
|---|---|---|
| Wikivoyage English travel guides (starter) | 290.8 MB | 34,597 records. English Wikivoyage guide text worldwide from the 2026-09-13 Kiwix snapshot; images are excluded. Opening hours, fares, visas, entry rules, local safety advice, and other travel details can change; verify time-sensitive details before travel. Two guides whose bodies carried upstream U+FFFD are excluded, so a question only they answered returns no match. Attribution rests on the pinned archive digest and each guide's revision-history URL because most guides carry no per-revision id. No target-device acceptance; the install-and-answer run is an emulator observation. |
| Repair and fixing · vehicles, bicycles, aviation, printing, woodworking | 256.6 MB | 78,626 records. English Stack Exchange repair and fixing questions from pinned 2026-10 Kiwix archives: motor vehicles, bicycles, aviation, 3D printing, and woodworking. Answers are included; images are excluded. Community answers are not guaranteed correct or current; safety-critical vehicle, aviation, and electrical repair must be checked against current manufacturer documentation. Unanswered questions and posts under the extraction thresholds are excluded. |
| Practical how-to · cooking, money, travel, home | 567.7 MB | 189,294 records. English Stack Exchange practical how-to questions from pinned 2026-10 Kiwix archives: cooking, personal finance, travel, and home improvement. Answers are included; images are excluded. Community answers are not guaranteed correct or current. Financial, legal, travel-entry, and home-safety details depend on jurisdiction and change over time; verify against current official sources. Unanswered questions and posts under the extraction thresholds are excluded. |
| Wikipedia English Top 1M introductions | 1.79 GB | 997,714 records. English Wikipedia lead sections of the top one million articles from the pinned 2026-04 Kiwix snapshot; images are excluded. Introductions only, not full article bodies. Introductions only; facts can be outdated or simplified. Per-article revision ids were not extracted, so exact revisions cannot be pinned (sampled verification only). Duplicate bodies and non-article pages were excluded. |
| Wikisource history and primary texts - volume 1 | 1.32 GB | 155,527 records. Volume 1 of 4 of the complete reviewed English Wikisource transcription edition from the 2026-09-08 Kiwix nopic snapshot: treaties, constitutions, court opinions, speeches, letters and published works, split deterministically by document-id hash. Images are excluded. This is one hash partition; the reviewed edition is complete only with all four volumes. Transcriptions are not critical editions: they can preserve source errors, historical spelling and omissions. 135 records whose bodies carried upstream U+FFFD were excluded, so a question only they answered returns no match rather than corrupted text. 2,897 of 622,014 records have no MediaWiki revision id but keep a history URL. Court opinions, constitutions, treaties and statutes may be amended, repealed or superseded and are not legal, medical or professional advice; verify the current official source. The split is deterministic, not topical. No target-device acceptance. |

Named clinic, hospital, and pharmacy places inside a 0.06 x 0.06 degree box around the Nairobi central business area, from a reviewed OpenStreetMap Overpass snapshot taken on 2026-10-24. Place tags and coordinates are a 2026-10-24 snapshot and can be stale, incomplete, or locally inconsistent; verify hours and services on site.

What each collection holds
Wikivoyage English travel guides is the starter and the broad destination collection. It is a snapshot, not an offline map or live travel service. Fares, entry requirements, opening hours, and local conditions can change after the snapshot.
Wikipedia English Top 1M introductions holds the lead sections of the most-read English articles. It is introductions only, so a full article body is not in the pack.
Repair and fixing holds community questions and answers about vehicles, bicycles, aviation, 3D printing, and woodworking. Practical how-to covers cooking, personal finance, travel, and home improvement. Answers are community-written, not guaranteed correct or current, and safety-critical repair must be checked against current manufacturer documentation.
History and primary texts is one reviewed Wikisource edition split across four volumes: treaties, constitutions, court opinions, speeches, letters, and published works. The split is deterministic by document hash, not by subject, so install all four volumes to hold the complete edition. Transcriptions are not critical editions, and laws and court opinions can be amended or superseded.
Nairobi health places lists 200 named clinics, hospitals, and pharmacies in central Nairobi from an OpenStreetMap snapshot. It does not report whether a place is open, how far it is, or how good it is.
