-# How to run
+# Test official and localhost API
+
+The goal of this project is to be able to contact the API while online & offline. The official API can be contacted while online, and the localhost one will be used when you are offline.  
+You can only access the dashboard when online. 
+
+*Not functional on Windows.*
+
+**Requirements:** 
+- Docker
+- scripts working on Ubuntu (other distributions not tested)
+- filling `install.env` with the credentials you want to use in localhost mode
+- filling `.env` *\*_OFFICIAL* and *\*_LOCALHOST* variables with the appropriate values
+
+OFFICIAL values can be found on [keygen.sh](https://app.keygen.sh/settings).  
+A token for the API will be generated on the first run. Execute the run.sh script two times to get both tokens: one while having Internet access and one without.
+
+**Linux:**
+
+```shell
+source install.sh
+```
+
+```shell
+source run.sh
+```
+In another terminal:
+```shell
+sudo dotnet run api
+```
+
+(You need to run it as root because sending an async ping is limited to root. If not running as root, the official API
+cannot be contacted.)
+
+# Run basic offline file verification
+
 ## Example config:
 
 **Linux / Windows:**
+
 ```shell 
 dotnet run examples/license.lic examples/machine.lic 198e9fe586114844f6a4eaca5069b41a7ed43fb5a2df84892b69826d64573e39
 ```
 
 ## Normal config:
-* Your fingerprint should be the hash of the serial number of your machine (you can execute the program to see it) computed with **SHA3_512** ([Online Converter](https://emn178.github.io/online-tools/sha3_512.html)).
+
+* Your fingerprint should be the hash of the serial number of your machine (you can execute the program to see it)
+  computed with **SHA3_512** ([Online Converter](https://emn178.github.io/online-tools/sha3_512.html)).
 * Replace the public key from [keygen.sh](keygen.sh) line 96 of `Program.cs`.
 * Get your machine file on [keygen.sh](keygen.sh) and put the raw license key in a new file named `license.lic`.
 * Put your `machine.lic` & `license.lic` in the same folder as `Program.cs` and run:
 
 **Linux:**
+
 ```shell
 sudo dotnet run
 ```
+
 (You need to run it as root because it needs to access `/dev/sda` to get the serial number of your machine.)
 
 **Windows:**
+
 ```shell
 dotnet run
 ```
 
 ## Docker:
+
 ```shell
 docker build . -t license-example-csharp
 docker run -it license-example-csharp
