# Add a customer to the users list
Adds or updates one row in the public adopters table on `/users`.
**Do not write a customer story in this skill.** If the user wants a full
`/users/<slug>` case study, use
[`customer-story-setup`](../customer-story-setup/SKILL.md) first, then come
back here to link it.
## Canonical file
| What | Where |
| -------------------------------- | --------------------------------------------------------------------------- |
| Adopters table (source of truth) | `components-mdx/adopters-table.mdx` |
| Rendered on | `/users` (`content/customers/index.mdx`) and the handbook customers chapter |
The handbook imports the same table (`<AdoptersTable />`). Editing the MDX
file updates both pages. Do **not** duplicate the table elsewhere.
## Before writing any file
Collect what you can from the request. Ask only for what is still missing:
1. **Company name** — public marketing name
2. **Company website** — used in the Company column
3. **Use case** — optional; write one if a user story or external link exists
4. **External reference URL** — optional public source (blog, job post, DPA, talk)
Then **always** check for a user story. Do not skip this step.
## Always check: is there a user story?
Search the working tree **and** `origin/main` (this branch may be behind):
- `content/customers/meta.json` → `pages` (skip `"index"`)
- `content/customers/*.mdx` — match company name, legal name, or obvious slug
variants (`hugging-face` vs `huggingface`, `merckgroup` vs `merck`)
- Frontmatter `showInCustomerIndex` and `quoteCompany` if the filename is unclear
The public URL is `/users/<slug>` where `<slug>` is the MDX filename without
`.mdx`.
| Result | Reference column (last) | Use case column (middle) |
| --------------------------------- | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- |
| **User story exists** | `[User Story](/users/<slug>)` | Brief summary of **how they use Langfuse** from the story (or the user's wording if they gave one) |
| **No story, external link given** | Briefly named link, see below | Brief summary of the Langfuse use case from that source |
| **No story, no external link** | `Langfuse Customer` | Short product/industry line if the user gave one; otherwise a concise public description of the company. Do not invent a Langfuse use case. |
Never write `Langfuse Customer` when a user story exists. Prefer the user
story over an external link when both exist.
## External reference links
When the user (or a public source they pointed at) provides a URL and there is
**no** user story:
1. Open the page and read enough to understand the Langfuse mention.
2. **Middle column:** one short use-case phrase (sentence case), focused on
what they do with Langfuse or their AI product — not a full company bio.
3. **Last column:** a short link label plus the URL, matching existing rows.
Link-label examples already in the table:
`Blogpost`, `Tech Blogpost`, `AWS Blogpost`, `LinkedIn Post`, `Job Description`,
`Case Study`, `Client Story`, `Documentation`, `Release Notes`, `Research Paper`,
`Source Code`, `Conference Talk`, `Conference Deck`, `Privacy Policy`,
`Data Processing Addendum`, `Subprocessor List`, `IT White Paper`,
`Technical Memorandum`, `Open Source Catalog`, `OSS LLMOps Stack`,
`Partner Newsletter`
Pick the closest label. Include a date only when it helps (`Blogpost from 12/23/2025`).
When other rows for similar sources include an archive, add one:
```md
[Tech Blogpost](https://example.com/post) ([Archive](https://web.archive.org/web/...))
```
Do not block the edit if no archive URL is available.
## Row format
Insert **alphabetically by company display name** (the visible name, not the
domain). Update an existing row instead of adding a duplicate.
```md
| [Company](https://www.example.com/) | Short use-case phrase | Langfuse Customer |
```
```md
| [Company](https://www.example.com/) | Short use-case phrase | [User Story](/users/<slug>) |
```
```md
| [Company](https://www.example.com/) | Short use-case phrase | [Tech Blogpost](https://example.com/post) ([Archive](https://web.archive.org/web/...)) |
```
- Company cell: markdown link to the official site. Add a parenthetical only
when the table already does that for subsidiaries (`(Wix)`, `(Toyota Group)`).
- Use case: sentence case; keep it to one line; American English; no em dashes
(use a regular hyphen or an em-dash character only if neighboring rows do).
- Preserve the existing column padding so the table stays aligned.
- One H1 per markdown file already exists in consumers; do not add a `# ` heading
to the table file.
## Optional companion updates (only if they already apply)
Do these only when the company is already on that surface, or the user asks:
| Surface | File | When |
| ------------------------- | ------------------------------------------ | ----------------------------------------------------------------------------------------- |
| Handbook featured bullets | `content/handbook/chapters/customers.mdx` | Company is in the curated list; add `[(Read Story)](/users/<slug>)` if a story exists |
| Homepage logo grid | `components/shared/EnterpriseLogoGrid.tsx` | Logo is already in the grid and a story exists → set `customerStoryPath: "/users/<slug>"` |
| Wrapped customers | `components/wrapped/Customers.tsx` | Same: move to `companiesWithStories` and `{ type: "story", name: "..." }` |
Do **not** add a homepage logo in this skill. That needs a designed 140×40 SVG
and is a separate request.
## Out of scope
- Creating `content/customers/<slug>.mdx` or editing `content/customers/meta.json`
→ `customer-story-setup`
- Designing or replacing homepage logos
- Inventing public citations or claiming a user story that does not exist
## Checklist
- [ ] Searched `content/customers/` and `origin/main` for a user story
- [ ] Reference is `User Story`, a described external link, or `Langfuse Customer`
- [ ] Use case is a brief, sourced summary (not a long paragraph)
- [ ] Company cell links to the official website
- [ ] Row is alphabetical and not a duplicate
- [ ] Table column alignment preserved
- [ ] `pnpm run format` if you edited Prettier-covered files
