+
+## Supported CI Pipelines
+
+* Github Actions
+* Gitlab CI
+* Travis CI
+* Custom CI, set enviroment `CI=true`
+
+## Download
+
+You can download the newest version under [releases](https://github.com/Nightapes/go-semantic-release/releases)
+
+or
+
+you can use a Docker image
+
+`docker pull nightapes/go-semantic-release:<VERSION>` or `docker pull docker.pkg.github.com/nightapes/go-semantic-release/go-semantic-release:<VERSION>`
 
 
 
-## Build
+## How to use
 
-`go build ./cmd/go-semantic-release/`
+`go-semantic-release` config file 
+Create a file with the name `.release.yml` or anything else, but you need to set to every command `-c <your config file>`
 
-## Run
+### Example config
 
-Print the next version
+```yml
+commitFormat: angular
+branch:
+  master: release
+release: 'github'
+github:
+  repo: "go-semantic-release"
+  user: "nightapes"
+assets:
+  - name: ./build/go-semantic-release
+    compress: false
+  - name: ./build/go-semantic-release.exe
+    compress: false
+hooks:
+  preRelease:
+    - name: echo $RELEASE_VERSION
+  postRelease:
+    - name: echo $RELEASE_VERSION
+```
 
-`./go-semantic-release version next`
+#### CommitFormat
 
-Set a version
+Set the commit format, at the moment we support ony [angular](https://github.com/angular/angular/blob/master/CONTRIBUTING.md#commit-message-format), more coming soon.
 
-`./go-semantic-release version set v1.1.1`
+```yml
+commitFormat: angular
+```
+
+#### Branch
+
+You can define which kind of release should be created for different branches. 
+
+Supported release kinds: 
+
+* `release` -> `v1.0.0`
+* `rc` -> `v1.0.0-rc.0`
+* `beta` -> `v1.0.0-beta.0`
+* `alpha` -> `v1.0.0-alpha.0`
+
+Add a branch config to your config
+
+```yml
+branch:
+  <branch-name>: <kind>
+```
+
+#### Release
+
+At the moment we support releases to gitlab and github.
+
+##### Github 
+
+You need to set the env `GITHUB_TOKEN` with an access token.
+
+```yml
+release: 'github'
+github:
+  user: "<user/group"
+  repo: "<repositroyname>"
+  ## Optional, if your not using github.com
+  customUrl: <https://your.github>
+```
+
+##### Gitlab 
+
+You need to set the env `GITLAB_ACCESS_TOKEN` with an personal access token.
+
+
+```yml
+release: 'gitlab'
+gitlab:
+  repo: "<repositroyname>"  ## Example group/project
+  ## Optional, if your not using gitlab.com
+  customUrl: <https://your.gitlab>
+```
+
+##### Git only 
+
+Only via https at the moment. You need write access to your git repository
+
+
+```yml
+release: 'git'
+git:
+  email: "<email>" # Used for creating tag
+  user: "<user>" : # Used for creating tag and pushing
+  auth: "<token>" # Used for pushing, can be env "$GIT_TOKEN", will be replaced with env
+```
+
+
+#### Assets
+
+You can upload assets to a release
+
+Support for gitlab and github.
+If you want, you can let the file be compressed before uploading 
+
+```yml
+assets:
+  - name: ./build/go-semantic-release
+    compress: false
+```
+
+#### Hooks
+
+Hooks will run when calling `release`. Hooks run only if a release will be triggered.  
+
+#### Changelog
+
+Following variables can be used for templates:
+*   `Commits` string
+*	`Version` string
+* 	`Now` time.Time
+* 	`Backtick` string
+* 	`HasDocker` bool
+* 	`HasDockerLatest` bool
+* 	`DockerRepository` string
+
+```yml
+changelog:
+  printAll: false ## Print all valid commits to changelog
+  title: "v{{.Version}} ({{.Now.Format "2006-01-02"}})" ## Used for releases (go template)
+  templatePath: "./examples/changelog.tmpl"    ## Path to a template file (go template)
+```
+
+##### Docker 
+
+You can print a help text for a docker image
+
+```yml
+changelog:
+  docker: 
+    latest: false ## If you uploaded a latest image
+    repository: ## Your docker repository, which is used for docker run
+```
+
+### Version
+
+`go-semantic-release` has two modes for calcualting the version: automatic or manual.
+
+#### Automatic
+
+Version will be calculated on the `next` or `release` command
+
+#### Manual
+
+If you don't want that `go-semantic-release` is calculating the version from the commits, you can set the version by hand with
+following command:
+
+```bash
+./go-semantic-release set 1.1.1
+```
+
+### Print version
+
+Print the next version, can be used to add version to your program
+
+```bash
+./go-semantic-release next // show next version (calculated by new commits since last version)
+./go-semantic-release last // show last released version 
+```
+Example with go-lang
+
+```bash
+go build -ldflags "--X main.version=`./go-semantic-release next`"
+```
+
+### Create release 
+
+```bash
+./go-semantic-release release 
+```
+
+
+
+## Build from source
+
+```bash
+go build ./cmd/go-semantic-release/
+```
+
+### Testing
+
+```bash
+go test ./... 
+```
+
+### Linting
+
+```
+curl -sfL https://install.goreleaser.com/github.com/golangci/golangci-lint.sh | sh -s -- -b $(go env GOPATH)/bin v1.16.0
+golangci-lint run ./...
+```
