+## Generate your transitland route shapes from gtfs trips
 
-This project aims to generate [transitland]() `gtfs routes` shapes from `gtfs trips` shapes.
+This project aims to generate [transitland]("https://github.com/interline-io/transitland-server") `gtfs routes` shapes from `gtfs trips` shapes.
 
+## Installation
+
+### Go binary
+
+`go install github.com/phoops/transitland-route-geometry-generator/...@latest`
+
+### Github release - recommended
+
+You can grab the latest release on this repository [releases]("https://github.com/phoops/transitland-route-geometry-generator/releases")
+
+### Docker image
+
+`phoops/transitland-route-geometry-generator`
+
+
+
+`docker run run --rm -ti phoops/transitland-route-geometry-generator 1 -d postgres://transit:transit@db/gtfsdb?sslmode=disable`
+## How it works?
+
+On `gtfs` spec, we don't have a direct association between `shapes` and `routes`, in `transitland` domain is possibile to associate a `geometry` to a `route`.
+
+In order to associate a `geometry` to a `transitland route`, we need to process the `route trips` and the `shapes` associated to the `trips`.
+
+In order to keep thing simple, we choose the `longest geometry` of all the `trips` and promote that geometry to the geometry of the `route`.
+
+This project depends on `postgresql` and `postgis` and we interact directly with the `transitland` database, so `transitland` schema is needed.
+
+### Steps
+
+- Fetch trips for a specific `gtfs` feed and `routes` (Both can be provided as input to the CLI)
+- Choose the `longest` shape associated to the `trips` of the routes
+- Take the `geometry` of chosen shape and promote that to `route` geometry
+- Persit the `geometry` in `tl_route_geometries table
+
+**The shapes generation is idempotent, so you can use the CLI freely in your workflow, without worring of breaking things, when the shapes geometry are updated by a new feed, they will be imported and the route shape is computed again**
+
+## Usage
+
+```bash
+    Generate geometries for your gtfs routes in transistland.
+    Uses your trips geometries in order to compute the route shape
+    More information at https://github.com/phoops/transitland-route-geometry-generator
+
+    Usage:
+    transitland-route-geometry-generator [command]
+
+    Available Commands:
+    completion  generate the autocompletion script for the specified shell
+    generate    Generate routes
+    help        Help about any command
+    version     Print the version
+
+    Flags:
+    -h, --help      help for transitland-route-geometry-generator
+    -v, --verbose   verbose output
+```
+
+### Generate routes
+
+```
+Usage:
+  transitland-route-geometry-generator generate [flags]
+
+Flags:
+  -d, --database string   postgres database connection string
+  -n, --dry-run           dry run generation, without inserts
+  -h, --help              help for generate
+  -r, --routes ints       route ids to include in generation, all by default
+```
+
+The `-v` flag will output more informations about the process, also the raw `postgresql` queries made by the cli.
+
+The `generate` command wants a single argument, representing the `id` of the `gtfs` feed, this id can be obtained querying `transitland`, or in the
+database table `current_feeds`.
+
+The `-d` flag is also required, you should specify a `postgresql` connection string, like `postgres://transit:transit@db/gtfsdb?sslmode=disable`.
+
+The `-r` flag will restrict the `route` shapes generation only to specific route `ids`, routes should be separated by comma, ex:  `-d 1,2,3,4`.
+
+**tl;dr:**
+
+
+
+`transitland-route-geometry-generator generate 1 -d "postgres://transit:transit@localhost/gtfsdb?sslmode=disable"`
+### Dry run
+
+If you want to only get the computed `shapes` for your routes, you can use the `-n` flag, this will skip the database write of `route shapes`.
+The output will be a table like that
+
+```bash
+{"level":"info","ts":"2021-11-30T12:56:58.274+0100","caller":"commands/generator.go:50","msg":"starting generation","command":"generate","verbose":false,"dry-run":true,"feed_version_id":1}
++----------+--------------+------------------+
+| ROUTE ID | DIRECTION ID | LONGEST SHAPE ID |
++----------+--------------+------------------+
+|        1 |            0 |                4 |
+|        1 |            1 |                2 |
+|        2 |            0 |                1 |
+|        2 |            1 |                8 |
++----------+--------------+------------------+
+{"level":"info","ts":"2021-11-30T12:56:58.350+0100","caller":"commands/generator.go:88","msg":"dry run completed, run again without the n flag","command":"generate","verbose":false}
+```
+
+If you pass the `-v` flag, the output will contain also the raw `geometry` and the `centroid` of shape.
+
+**tl;dr:**
+
+
+`transitland-route-geometry-generator generate 1 -n -d "postgres://transit:transit@localhost/gtfsdb?sslmode=disable"`
