 ### Load order / precedence
 The order of loading:
 1. **params.js file** - ServiceParams instance gets loaded along with the default values;
-2. **params.ENV_NAME.js file** - the one that overrides values in ServiceParams per env - **if LOCAL_OVERRIDES env var is set**;
+2. **params.ENV_NAME.js file** - the one that overrides values in ServiceParams per env;
 3. **IConfigsProvider** - if a correspondent key name exists the value from the provider overrides the current one;
 4. **Environment vars** - all parameters can be overridden by passing an uppercase env var with the param key name 
 
 In summary, env vars always win (if defined).
