+## Releasing
+
+CLI tool and FastEdge lib are released with GitHub using [cargo-release](https://github.com/crate-ci/cargo-release) tool. 
+The release process includes next steps:
+* increment crate version in Cargo.toml
+* generate CHANGELOG.md file
+* push version tag 
+* create GitHub release and build artefacts
+
+### Prerequisites
+
+Install cargo release:
+``` 
+cargo install cargo-release
+```
+Install [git-cliff](https://git-cliff.org) (tool to generate changelog from Git history):
+```
+cargo install git-cliff
+```
+### Creating new release
+
+We are using GitFlow strategy. That means that everything in `main` branch should be ready to be released. 
+To create a new release it is necessary to checkout a new release branch with next naming convention: `releases/vX.Y.Z`.
+Where the `vX.Y.Z` is the next version number.
+
+```
+    cargo release <LEVEL> --execute
+```
+This command will commit and push to remote changed Cargo.toml and CHANGELOG.md files. And also add a tag for current release. 
+Once the release branch is pushed on remote it triggers the release process as GitHub Action.
+
+Note: It also creates a PR for `releases/**` branch to merge it to `main` as soon as release is ready.
+
+#### Release bump level
+
+* `release`: Remove the pre-release extension; if any (0.1.0-alpha.1 -> 0.1.0, 0.1.0 -> 0.1.0).
+* `patch`:
+    * If version has a pre-release, then the pre-release extension is removed (0.1.0-alpha.1 -> 0.1.0).
+    * Otherwise, bump the patch field (0.1.0 -> 0.1.1)
+* `minor`: Bump minor version (0.1.0-pre -> 0.2.0)
+* `major`: Bump major version (0.1.0-pre -> 1.0.0)
+* `alpha`, `beta`, and `rc`: Add/increment pre-release to your version
+  (1.0.0 -> 1.0.1-rc.1, 1.0.1-alpha -> 1.0.1-rc.1, 1.0.1-rc.1 ->
+  1.0.1-rc.2)
