### Construct line protocol
11-
12-
With a [basic understanding of line protocol](/influxdb3/version/write-data/#line-protocol),
13-
you can construct line protocol data and write it to {{% product-name %}}.
14-
15-
All InfluxDB client libraries write data in line protocol format to InfluxDB.
16-
Client library `write` methods let you provide data as raw line protocol or as
17-
`Point` objects that the client library converts to line protocol. If your
18-
program creates the data you write to InfluxDB, use the client library `Point`
19-
interface to take advantage of type safety in your program.

Consider a use case where you collect data from sensors in your home. Each
24-
sensor collects temperature, humidity, and carbon monoxide readings.
12+
Set up your {{< product-name >}} project and credentials
13+
to write data using the InfluxDB 3 client library for your programming language
14+
of choice.

To collect this data, use the following schema:
27-
28-
<!-- vale InfluxDataDocs.v3Schema = YES -->
29-
30-
- **table**: `home`
31-
- **tags**
32-
- `room`: Living Room or Kitchen
33-
- **fields**
34-
- `temp`: temperature in °C (float)
35-
- `hum`: percent humidity (float)
36-
- `co`: carbon monoxide in parts per million (integer)
37-
- **timestamp**: Unix timestamp in _second_ precision

### Construct line protocol
205+
206+
With a [basic understanding of line protocol](/influxdb3/version/write-data/#line-protocol),
207+
you can construct line protocol data and write it to {{% product-name %}}.
208+
209+
Use client library write methods to provide data as raw line protocol
210+
or as `Point` objects that the client library converts to line protocol.
211+
If your program creates the data you write to InfluxDB, the `Point`
212+
interface to take advantage of type safety in your program.
183213

184214
Client libraries provide one or more `Point` constructor methods. Some libraries
185215
support language-native data structures, such as Go's `struct`, for creating
186216
points.
187217

218+
Examples in this guide show how to construct `Point` objects that follow the [example `home` schema](#example-home-schema),
219+
and then write the points as line protocol data to an {{% product-name %}} database.
220+
221+
#### Example home schema
222+
223+
Consider a use case where you collect data from sensors in your home. Each
224+
sensor collects temperature, humidity, and carbon monoxide readings.
225+
226+
To collect this data, use the following schema:
227+
228+
<!-- vale InfluxDataDocs.v3Schema = YES -->
229+
230+
- **table**: `home`
231+
- **tags**
232+
- `room`: Living Room or Kitchen
233+
- **fields**
234+
- `temp`: temperature in °C (float)
235+
- `hum`: percent humidity (float)
236+
- `co`: carbon monoxide in parts per million (integer)
237+
- **timestamp**: Unix timestamp in _second_ precision
