-# cjseq
-
-[![crates.io](https://img.shields.io/crates/v/cjseq.svg)](https://crates.io/crates/cjseq)
-
-`cjseq` is a Rust libray+binary for creating, processing, and modifying [CityJSONSeq](https://cityjson.org/cityjsonseq) files, as well as converting to/from [CityJSON](https://cityjson.org).
-
-## Installation
-
-### Installing the binary
-
-1. Install the [Rust compiler](https://www.rust-lang.org/learn/get-started)
-2. Run `cargo install cjseq`
-3. Then a binary called `cjseq` is installed system-wide
-
-### Installing the library
-
-1. Install the [Rust compiler](https://www.rust-lang.org/learn/get-started)
-2. Run `cargo install cjseq`
-
-### Compiling the project
-
-1. Install the [Rust compiler](https://www.rust-lang.org/learn/get-started)
-2. Clone the repository: `git clone https://github.com/cityjson/cjseq.git`
-3. Build the project: `cargo build --release`
-4. Run the program: `./target/release/cjseq --help`
-
-## Usage
-
-`cjseq` takes input from either a file or the standard input (stdin, if no file path is given as argument), and it always outputs the results to the standard output (stdout). 
-The output can be a CityJSON object or a CityJSONSeq stream.
-
-### Convert CityJSON to CityJSONSeq
-
-Convert a CityJSON file to a CityJSONSeq stream:
-
-```sh
-cjseq cat myfile.city.json > myfile.city.jsonl
-```
-
-Alternatively, to use stdin:
-
-```sh
-cat myfile.city.json | cjseq cat
-```
-
-### Convert CityJSONSeq to CityJSON
-
-Convert a CityJSONSeq stream to a CityJSON file:
-
-```sh
-cat ./data/3dbag_b2.city.jsonl | cjseq collect > 3dbag_b2.city.json
-```
-
-```sh
-cjseq collect ./data/3dbag_b2.city.jsonl > 3dbag_b2.city.json
-```
-
-[Globbing](https://en.wikipedia.org/wiki/Glob_(programming)) works for the `collect` command:
-
-```sh
-cat ./data/*.city.jsonl | cjseq collect > hugefile.city.json
-```
-
-### Filter CityJSONSeq
-
-`cat myfile.city.jsonl | cjseq filter --bbox 85007 446179 85168 446290 > mysubset.city.jsonl`
-
-## Input constraints
-
-  1. the input CityJSON/Seq must be v1.1 or v2.0 (v1.0 will panic).
-  2. the input JSON must be CityJSON schema-valid, use [cjval](https://github.com/cityjson/cjval) to validate.
