 ### Create a new database
 The so-called database (in the form of `blocking.p`) is a file storing all the matching entities (ASN, IPs, hostnames, zones…) and every entity leading to it.
-It exists because the list cannot be generated in one pass, as DNS redirections chain links do not have to be inputed in order.
+For now there's no way to remove data from it, so here's the command to recreate it: `./db.py --initialize`.
 You can purge of old records the database by running `./prune.sh`.
 When you remove a source of data, remove its corresponding file in `last_updates` to fix the pruning process.

+> Some VPS providers might detect this as a DDoS attack and cut the network access.
 > Some Wi-Fi connections can be rendered unusable for other uses, some routers might cease to work.
 > Since massdns does not support yet rate limiting, my best bet was a Raspberry Pi with a slow ethernet link (Raspberry Pi < 4).
 The DNS records will automatically be imported into the database.
 If you want to re-import the records without re-doing the resolving, just run the last line of the `./resolve_subdomains.sh` script.
 ### Import DNS records from Rapid7
 Just run `./import_rapid7.sh`.
 This will download about 35 GiB of data, but only the matching records will be stored (about a few MiB for the tracking rules).
 Note the download speed will most likely be limited by the database operation thoughput (a quick RAM will help).
 ### Export the lists
-For the tracking list, use `./export_lists.sh`, the output will be in the `dist` folder (please change the links before distributing them).
+For the tracking list, use `./export_lists.sh`, the output will be in the `dist` forlder (please change the links before distributing them).
 For other purposes, tinker with the `./export.py` program.
 #### Explanations
 Note that if you created an `explanations` folder at the root of the project, a file with a timestamp will be created in it.
 It contains every rule in the database and the reason of their presence (i.e. their dependency).
 This might be useful to track changes between runs.
 Every rule has an associated tag with four components:
 1. A number: the level of the rule (1 if it is a rule present in the `rules*` folders)
 2. A letter: `F` if first-party, `M` if multi-party.
 3. A letter: `D` if a dupplicate (e.g. `foo.bar.com` if `*.bar.com` is already a rule), `_` if not.
 4. A number: the number of rules relying on this one
 ### Generate the index webpage
 This is the one served on <https://hostfiles.frogeye.fr>.
 Just run `./generate_index.py`.
 ### Everything
 Once you've made sure every step runs fine, you can use `./eulaurarien.sh` to run every step consecutively.

 However, to circumvent this block, tracker companies made the websites using them load trackers from `somestring.website1.com`.
 The latter is a DNS redirection to `website1.trackercompany.com`, directly to an IP address belonging to the tracking company.
 Those are called first-party trackers.
 On top of aforementionned privacy issues, they also cause some security issue, as websites usually trust those scripts more.
 For more information, learn about [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP), [same-origin policy](https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy) and [Cross-Origin Resource Sharing](https://enable-cors.org/).
 In order to block those trackers, ad blockers would need to block every subdomain pointing to anything under `trackercompany.com` or to their network.
 Unfortunately, most don't support those blocking methods as they are not DNS-aware, e.g. they only see `somestring.website1.com`.
 This list is an inventory of every `somestring.website1.com` found to allow non DNS-aware ad blocker to still block first-party trackers.

 It should be safe from false-positives.
 It also contains all tracking hostnames under company domains (e.g. `website1.trackercompany.com`),
 useful for ad blockers that don't support mass regex blocking,
 while still preventing fallback to third-party trackers.
 Don't be afraid of the size of the list, as this is due to the nature of first-party trackers: a single tracker generates at least one hostname per client (typically two).
 ### First-party only trackers
