# Locations Service
|
||||
|
||||
This is the Locations service
|
||||
|
||||
Generated with
|
||||
|
||||
```
|
||||
micro new locations
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Generate the proto code
|
||||
|
||||
```
|
||||
make proto
|
||||
```
|
||||
|
||||
Run the service
|
||||
|
||||
```
|
||||
micro run .
