+# Running the Edgee proxy locally
+
+Edgee acts as a reverse proxy in front of a website, intercepting HTTP requests and running business logic on top of edge networks and CDNs such as Fastly and Cloudflare; the proxy interacts with WebAssembly components to implement features such as data collection for analytics, warehousing, and attribution data.
+
+Once you have a valid configuration file (see next section), you can run the Edgee proxy in different ways, using the installer, Docker or running as a Rust crate.
+
+⚠️ Note: all the examples below assume that TLS certificates and WebAssembly components can be found in `/var/edgee/cert` and  `/var/edgee/wasm` respectively. Feel free to use `/local/cert` and `/local/wasm` for local development.
+
+# Install the Edgee CLI
+
+You can install and run `edgee` locally using the installer script:
+
+```shell
+$ curl https://install.edgee.cloud | sh
+```
+
+Or via homebrew:
+
+```shell
+$ brew tap edgee-cloud/edgee
+$ brew install edgee
+```
+
+Once installed, you can run the local proxy as follows:
+
+```shell
+$ edgee serve
+```
+
+
+### Alternative installation methods
+
+#### Using Docker
+
+You can run it using the Docker CLI:
+
+```shell
+docker run \
+  -v $PWD/edgee.toml:/app/edgee.toml \
+  -v $PWD/cert:/var/edgee/cert \
+  -v $PWD/wasm:/var/edgee/wasm \
+  -p80:80 \
+  -p443:443 \
+  edgeecloud/edgee
+```
+
+Or as part of a `docker-compose.yml`:
+
+```yaml
+service:
+  edgee:
+    image: edgeecloud/edgee
+    ports:
+      - "80:80"
+      - "443:443"
+    volumes:
+      - "./edgee.toml:/app/edgee.toml"
+      - "./cert:/var/edgee/cert"
+      - "./wasm:/var/edgee/wasm"
+```
+
+#### Building from source
+
+Build the Rust package using Cargo:
+
+```console
+cargo build --release
+```
+
+Then you can run the local proxy:
+
+```console
+cargo run --release serve
+```
+
+# Configuration
+
+Edgee proxy is customized through the `edgee.toml` file (or `edgee.yaml`), which is expected in the current directory.
+
+You can get started by coping the existing `edgee.sample.toml` file:
+
+```bash
+cp edgee.sample.toml edgee.toml
+```
+
+Here's a minimal sample configuration that sets Edgee to work as a regular reverse proxy. Later we'll see how to enable WebAssembly components.
+
+```toml
+# edgee.toml
+[log]
+level = "info"
+
+[http]
+address = "0.0.0.0:80"
+force_https = true
+
+[https]
+address = "0.0.0.0:443"
+cert = "/var/edgee/cert/server.pem"
+key = "/var/edgee/cert/edgee.key"
+
+[[routing]]
+domain = "demo.edgee.dev"
+
+[[routing.backends]]
+name = "demo"
+default = true
+address = "192.168.0.10"
+enable_ssl = true
+```
+
+## Log levels
+Edgee allows you to control the granularity of logs you want to be displayed. The possible values are:
+`trace`, `debug`, `info`, `warn`, `error`, and `fatal`. This setting defines the minimal level to
+be displayed, so setting it to `warn` will show `warn`, `error`, and `fatal` messages while hidding the others.
+
+## Routing
+The example above sets up one backend called "demo". As the default backend, it will receive all traffic directed to `demo.edgee.dev`. Additionaly, projects can have a number of backends and use routing rules to distribute traffic among them.
+
+For example, we could add a second backend called "api" to handle all requests to `demo.edgee.dev/api`:
+
+```toml
+# edgee.toml
+[[routing.rules]]
+path_prefix = "/api/"
+backend = "api"
+
+[[routing.backends]]
+name = "api"
+enable_ssl = true
+address = "192.168.0.30"
+```
+
+The supported matchers are:
+- *path*: the path matches exactly the provided value
+- *path_prefix*: the path starts with the provided value
+- *path_regexp*: the path matches the provided regexp
+
+In addition to proxying the request, you could also rewrite the path:
+
+```toml
+# edgee.toml
+
+[[routing.rules]]
+path_prefix = "/api/"
+rewrite = "/v1/"
+backend = "api"
+```
+
+This way, calling `/api/test` on port `80` will result in calling `/v1/test` on the API backend.
+
+### Redirections
+
+Edgee supports HTTP redirections, allowing you to redirect traffic temporarily from one URL to another. 
+
+#### Example
+
+Here's how you can set up a redirection in your `edgee.toml` configuration file:
+
+```toml
+# edgee.toml
+[[routing.redirections]]
+source = "/old-path"
+target = "https://example.com/new-path"
+
+
+[[routing.redirections]]
+source = "/foo"
+target = "/bar"
+```
+
+In this example, requests to `https://demo.edgee.dev/old-path` will be temporarily (HTTP 302) redirected to `https://example.com/new-path` and requests to `https://demo.edgee.dev/foo` will be redirected to `https://demo.edgee.dev/bar`
+
+
+
+## Integrating with edgee components
+
+Check out the [official components docs](https://www.edgee.cloud/docs/components/overview) to dive into the
+components architecture.
+
+The Edgee proxy is designed for performance and extensibility, so you can easily integrate open source components based on the platforms you need. Here's a list of the components we've built so far:
+- [Amplitude](https://github.com/edgee-cloud/amplitude-component)
+- [Google Analytics](https://github.com/edgee-cloud/ga-component)
+- [Segment](https://github.com/edgee-cloud/segment-component)
+- [Piano Analytics](https://github.com/edgee-cloud/piano-analytics-component)
+
+You just need point to the WebAssembly implementation in your proxy configuration. You may also build your
+own components for integrations we don't provide yet.
+
+### Example
+
+Let's see how to implement data collection using the [amplitude component](https://github.com/edgee-cloud/amplitude-component).
+
+You simply need to add a new session to your configuration pointing to the WebAssembly component that implements the data collection protocol:
+
+```toml
+# edgee.toml
+[[components.data_collection]]
+id = "amplitude"
+file = "/var/edgee/wasm/amplitude.wasm"
+settings.amplitude_api_key = "YOUR-API-KEY"
+```
+
+### Debugging a component
+
+You can enable debug logs for a specific component by setting the `debug` flag to `true`:
+
+```bash
+./edgee --debug-component amplitude serve
+```
