+# Overview
+
+PocketBase data import tools for CSV and JSON files made using
+[PocketBase JS SDK](https://github.com/pocketbase/js-sdk).
+
+Automatically creates typed PocketBase collection and populates it with data.
+
+Columns conflicting with PocketBase's autogenerated system fields (`id`,
+`created`, `updated`; case-insensitive check, target column name's case is not
+affected) are prefixed with `_`.
+
+## Types
+
+`pocketbase-import` detects types using regular expressions. Currently supported
+PocketBase types are:
+
+- `Bool`
+- `Number`
+- `Plain text`
+- `Email`
+- `DateTime`
+- `JSON`
+
+# Configuration
+
+In the root directory create `.env` file with the following environment
+variables:
+
+- `ADMIN_EMAIL` (required) - superadmin email
+- `ADMIN_PASSWORD` (required) - superadmin password
+- `POCKETBASE_URL` (optional) - PocketBase app URL, defaults to local instance
+
+Place your import files inside of `input` directory.
+
+# Options
+
+You can change the default import options to your needs:
+
+| Name      | Files    | Required | Description                                                                                | Example use         |
+| --------- | -------- | -------- | ------------------------------------------------------------------------------------------ | ------------------- |
+| input     | CSV/JSON | Yes      | The name of the input file (with extension)                                                | --input=example.csv |
+| id        | CSV/JSON | No       | Indicates that `_id` column should be typed as plain text, the type is detected by default | --id                |
+| lf        | CSV      | No       | LF (`\n`) EOL character will be used instead of default CLRF (`\r\n`)                      | --lf                |
+| delimiter | CSV      | No       | Column value separator, defaults to `,`                                                    | --delimiter=;       |
+| quote     | CSV      | No       | Value quote character, defaults to `'`                                                     | --quote=~           |

+# CSV
+
+## Examples
+
+Basic import (root directory):
+
+```
+deno run csv.ts --input=example.csv
+```
+
+Import without permission prompts and with `_id` column as text:
+
+```
+deno run --allow-read --allow-env --allow-net csv.ts --input=example.csv --id
+```
+
+Import with custom parser options (you need to adjust `example.csv`):
+
+```
+deno run csv.ts --input=example.csv --delimiter=; --query=~ --lf
+```
